The Zebra Danio is one of the fish that has been in the hobby forever. They are commercially bred and are available for sale in virtually every pet store, commonly being one of the first fish people keep when entering the hobby. For this reason, they are easily overlooked by more seasoned hobbyists when choosing inhabitants for their aquarium. This spring, the temperatures outside were still chilly, but I was beginning to see mosquito larvae outside in my pond. I went to my favorite fish store, and asked the owner what he suggested for a reasonably cold-tolerant fish that would provide mosquito protection, and he suggested the Zebra Danio.

For all of the reasons I mentioned above, I was hesitant, but the price was right (less than $.99/fish) so I came home with a dozen fish. They cleared out the mosquito larvae problem nearly overnight, and were quite active in the pond. Also, outside in the full sun, I noticed far more colors than their typical brown and tan zebra stripes. Flashes of blue or green iridescence showed up, as well as, yellow on the tops of their fins. Before long, I noticed lots of small fry swimming outside in the pond. My dozen fish had easily tripled, if not more.

When fall came, and the nighttime temperatures began to decline again, I brought the danios inside and placed them in a riparium/terrarium setup that I have going. I thought they would like the extra water flow I have in that particular aquarium, and so far they don’t seem to have any complaints. They are probably the best schoolers and most active fish I’ve kept in a planted aquarium. They might stress more calm/docile tank mates, but they are fun to watch as they never stop schooling from one side of the tank to the other. If you’re looking for an inexpensive schooling fish for your planted aquarium, you really can’t go wrong with the Zebra Danio.

I went to feed the fish in my 75G this evening, and to my delight, one of my three Nannacara anomala females (I have a male and 3 females) were guarding a swarm of fry in the front right of the tank. Fortunately, this is the perfect place to take pictures, despite the dirty glass.

I’m wondering if the other females are also holding fry because the male was staying in another territory with another female, and wouldn’t come out in the open for a picture. Two of the three females are in breeding coloration, which is a predominantly black body with yellow highlights. Their normal coloration is mostly a drab yellow.

The fry were grazing on tiny micro-particles in the beard algae. (Yes I have a little bit of beard algae.) I dissolved a small amount of frozen brine shrimp, which floated down toward them. Being frozen, there were plenty of other smaller particles that the fry were able to fit in their tiny mouths. The female (and other fish) took care of the larger brine shrimp.

These Nannacara anomala are incredibly entertaining fish to watch. The females all have their territories, and the male glides back and forth between them without any commotion. If a female strays too far from her territory, a bordering female makes sure to chase her away, flaring fins and nipping. Fortunately, there’s plenty of room in the 75G for them to occupy without any major damage. Now, I need to focus on rising up these fry!

It’s been about a month and a half since I rescape my 75G aquarium. As you can see, the plants are all grown in pretty well across the board. The Glossostigma elatinoides in the foreground has reached critical mass, and has carpeted 95% of the area in front. It won’t be long before it has fully filled out. The background plants are all growing very nicely, as well, but I still need to yank some of the some between the two mounds to make them more distinct. (Sometimes, I have a problem holding onto plants I like, even though they’re cluttering an aquascape.)

I could probably stand to add a few more fish to this aquarium that would occupy the upper regions of the water. I have catfish and cichlids in there, which occupy the lower regions, but only a few remaining rainbowfish swim freely up above. The easy solution would be to add all of the zebra danios which have been breeding outside in my pond now that the weather is getting a bit cooler. We’ll see if that happens or not, as I don’t want them picking off any Nannacara anomala fry should the parents breed. Comments/critiques welcome!

I finally got past my resistance and tore down the “Fallen Tree” aquascape in my 50G. I really wanted an aquascape where I can use some nice stem plants, but the manzanita hardscape seen below really just needs a simple low-to-the-ground type design on the right side. The stem plants I had in there looked okay, but didn’t really work with the hardscape.

So, Wednesday evening I tore out all of the plants and hardscape, and made myself a new rockscape using the new rocks I collected from my friend’s backyard. In his neighborhood, construction of the homes sometimes involves dynamite to dig out for the foundation, which conveniently leaves mounds of quartz-based rocks all over the place. I thought a rock-dominated aquascape would allow me to use the stem plants more effectively because the rocks would hide the bottoms, allowing nicely trimmed tops to pop out from behind them.

Above, you can see what I came up with. The foreground is still all Eleocharis sp. ‘Japan’, with a midground almost 100% comprised of Blyxa japonica. Blyxa aubertii is in the back-left with Limnophila repens var. ‘Mini’, Rotala sp. ‘Araguaia’, Ludwigia senegalensis, Pogostemon erectum, and Rotala mexicana var. ‘Araguaia’ making up the background. Comments welcome!

Back in July, I converted my quarantine tank into something of an aquascaped quarantine tank. Then, after rescaping my 75G, I had lots of extra Bolbitis, which I incorporated into this scape. This tank is really just a holding ground for plants and fish, with no CO2, minimal dosing, and a crappy light. Nevertheless, there’s no reason why it can’t look somewhat presentable.

Above is what it’s looking like currently (despite the poor picture). The Sagittaria subulata is slowly creeping to the right to fill in that side, and the crypts on the left side are gradually filling that in. The Bolbitis easily filled up the space in the back right, and behind the rock on the left. Overall, it’s coming along. There’s definitely an appeal to this low-tech tank because they grow so slowly that you only need to trim a couple times a year. Comments welcome!

Today I did water-changes on my aquariums, and while looking at the 54G tank, I decided to actually try trimming back the hairgrass a little bit. I had talked about trimming it down for awhile, but various folks said they liked the long-wavy-look, so I put it off. I ended up deciding to just try it once and see how it goes.

Above you can see the trimmed tank immediately after the water-change. Below is the tank, immediately prior to the trim and water change. Which do you like better? To me, I think the trimmed look brings out the hardscape a little bit more. I know that the rest of the plants are a bit of a mess right now. That’s my next problem to solve!

The good thing is that the plants are actually starting to grow quite well, and assuming I keep my dosing regimen and water-changes on schedule, I haven’t had near the issues with algae that I have had previously on this tank. The Potamogetons in this tank are doing wonderfully.

I did have a beautiful stand of Lindernia dubia in here, but I trimmed it very hard to send to a friend. I may have trimmed it too hard. Fortunately, I have more stashed away in my emersed setup. Overall, this tank is starting to come into its own. Please let me know if you like the haircut or not. Comments welcome!

It’s been a few weeks since I replanted the 50G, and as you can see the plants have been growing quite well. The tank is definitely due for a trim right now, especially the Ludwigia brevipes on the left, and the Limnophila repens var. ‘Mini’ in the back left. I do have two notable additions to this aquascape. In the back-left, I added a number of Blyxa aubertii plants which were previously in my 75G aquarium.

Also, I was fortunate to get in on a fantastic group buy that GWAPA conducted to add 15 crystal red shrimp, and 15 crystal black shrimp to this aquarium. Below is a picture of one of the red ones, which I believe is a “tiger-tooth” because the one red band looks like two teeth coming down. I don’t know very much about grading the shrimp, and really don’t care, as I just think they’re quite striking inhabitants in a planted aquarium regardless of the grade.

So, hopefully, these shrimp will start a little breeding population in my 50G! Elsewhere in the aquarium, the hairgrass is starting to spread in the corners where I transplanted a few plants, and I’m generally pleased with the direction that it’s headed. I’m waiting on the stems on the right side to grow out a bit more and multiply, so that I can really focus on trimming them into new compact bushes of plants. Comments/critiques welcome!

Last week, I finally got around to clearing out the jungle that had formed in my 75G, and completely rescaped it. Previously, the aquascape was dominated by a ton of Narrow Leaf Java Fern, but this scape doesn’t contain any fern, except for some Trident Java Fern topping off the two mounds of driftwood.

75G: 2 Days After Setup

I had a couple of goals in mind for this new scape. For one, with my farm tank overflowing with plants, I wanted to use a few more stem plants in this scape than I did in the previous one. Hence, ferns are out, and stems are in. Additionally, since I’ve had some plecos breeding in the hollowed out driftwood, I wanted to continue to use the same African bogwood as I had in here previously, but I also wanted some more open space for a foreground. Those were the goals.

75G: Hardscape Finished

Toying around with a couple of different layouts, I ultimately settled on the two mound approach, with one larger mound on the left, complemented by a smaller mound on the right, with open space in between. Yes, I know it’s been done a million times. So, I stacked up a bunch of pieces of the bogwood, trying to making them look like they fell on top of, or in the nook and crannies between, a base of rock.

75G: Foundation Plants Planted

After finishing the hardscape, I planted what I feel are foundation plants. These are the plants that are actually kind of part of hardscape itself. Plants like Cryptocoryne, Anubias, Java Fern, etc. After getting those in place, you can really start to see what other areas need to be filled in. I added an inch or two of water, and finished planting the foreground and stem plants. The foreground is Glossostigma elatinoides, and in the back I have Hygrophila sp. ‘Guinea,’ Ludwigia repens x arcuata, Ludwigia arcuata, Elatine americana, Clinopodium brownei, Hottonia palustris, Limnophila aromatica, and Limnophila sp. ‘Wavy’. Of course, you can’t see most of them now.

75G: Other Plants Planted, Filling Up Tank

After filling up the tank, this is what I had. I removed a ton of Malaysian Trumpet Snails so they wouldn’t uproot the foreground, and hundreds of cherry shrimp came out of the substrate to begin exploring their new home. It’s very difficult to catch all of the shrimp when doing a rescape, but fortunately, most survived the ordeal.

75G: Right After Scaping

So now, it’s just a matter of letting it grow in a little bit. I already see a few things I’ll probably end up tweaking. I probably ought to pull out some of the background plants between the two mounds to keep them more seperate, and have the Glosso extend all the way to the back. Additionally, the Cryptocoryne pontederiifolia behind the right mound should probably be moved to the right a little bit. I may adjust some of the hardscape on the left side, but at this point, I kind of want to see how it evolves on its’ own, and go from there. Comments and critiques welcome!

Last weekend, while I was trying to get pictures of the Apistogramma baenschi “Inka” in my 20L, I also snapped a few shots of the Nerite snails and Amano shrimp while waiting for the Apistos to come out of hiding. I wanted to share a few of those shots.

Olive Nerite Snails are by far one of the best algae eaters you can add to your aquarium, but many of them are quite pretty as well. I love the spiraling parallel lines patterned over many of their shells. I thought this guy (above) looks pretty good against the orange tones of the rock.

One of their key attributes is their willingness to slither along the glass, cleaning it of green spot, or other tough algae. You can see that this particular snail’s shell is slowly eroding away due to the lower pH and hardness of my water. This is fairly common in planted aquariums, especially when CO2 is injected as the carbonic acid is hard on their shells. I’ve known some hobbyists who used reef epoxy to fill in these holes, prolonging the life of their invert inhabitants.

Amano shrimp are the other must have invert in nearly every aquarium. They can clear a field of hair algae in a matter of days, if added in proper proportion to the size of the tank. (That, by the way, is probably roughly 1 shrimp/2 gallons.) Too many, with too little algae, and they will start eating your moss fronds, or other delicate leaved plants. To minimize that, I feed mine algae wafers. The largest Amano in the tank usually swims right to the wafer, and holds it captive until he’s eaten his fill. Then the rest of the invertibrates in the tank swarm the leftovers. A day of the life of an invert.

My 50G had turned into quite the farm tank, but I’ve finally been able to reclaim it as an aquascapable aquarium. I really like the hardscape, so I’ve decided to leave that in place, but simply replant it with some different plants. Previously, the aquascape was dominated by Blyxa japonica, where now I’ve only retained that in the middle to the right of the large piece of wood.

I’ve added a number of stem plants, and I’m hoping to trim them into bushes, kind of dutch style, behind the rocks to the right. I’m still deciding whether or not to keep the Eleocharis sp. ‘Japan’ in the foreground, or to rip it out and go with something more vintage like Glossostigma elatinoides. Comments welcome!
