The video quality isn’t fantastic, but hopefully you can still see how entertaining and beautiful these little fish are…

As you can see above, the two tanks sit side-by-side. That doesn’t mean it’s an easy job to swap their positions. I still had to drain the water, remove the plants, remove the rocks, remove the fish, remove the driftwood, and finally get help to physically move them. In other words, it was nearly the same amount of work as if I were moving to another house.

After getting the aquariums into their new resting places, I decided that it was time to re-aquascape the 50G. I didn’t want to change too much from how it was before, but I definitely needed to make some changes. So, I repositioned the wood countless times until I came up with what you see above.

Then, I replanted the Blyxa aubertii on the back left and added Hygrophila sp. ‘Guinea’ to the back right. Hopefully with some time, everything will fill in and look a lot better than it did previously. I’m still toying with the idea of adding the branches back into the scape to give the feel of a riverbank, but I’ll let the plants grow in a bit before doing that. Comments welcome!

The parents have left them to fend for themselves, although so far they are getting along just fine with the parents. I don’t completely know how many young fish I have, however, because they have dispersed throughout the tank, and the only time I ever seen a number of them together is when I’m feeding them. At those times, I’ve counted 7-8 together, but it wouldn’t surprise me to have double that number hiding in the overgrown farm tank.

They have yet to get the brilliant colors that the parents display, but you can definitely tell that they’re kribs now. Small patches of color are starting to show up around the gills and fins. They have the distinctive squat (or maybe pear shaped) body where the belly seems a little bit too big in comparison to the rest of the fish. I’m not able to sex them yet, but I’m never great at that anyways with most fish.

I’m really pleased with how easy these fish have been to keep and raise. The only thing I’m worried about is if the parents spawn again, and decide they don’t want their previous brood around anymore. If I see signs of spawning though, I may pull the parents out to their own tank to do their business.

I think the problem stemmed from not rinsing out the top-layer of the substrate when I moved the tank. Anyone who’s ever used ADA Aquasoil before knows that after awhile, parts of the substrate can degrade into mud. I should have washed away this mud when I did the move. Instead, the mud kept getting uprooted into the water column, coating the plants, and causing algae.

So, in effect, that’s what I spent several hours yesterday doing. I removed nearly all of the plants from the tank. Moved the fish into my new 54G native-themed aquarium, and proceeded to empty and fill the aquarium several times in order to vacuum all of the substrate.

I can only hope that now I’m all set to continue getting great growth from this tank. The other benefit of me doing this is that I was able to rearrange all of the plants in the tank, thin some of them out, and free up a lot of room for more plants. Collectoritis here I come!

One of the benefits of keeping an aquarium like this, as opposed to an emersed tank, is that plants grown in here are immediately ready to go into another aquarium when needed. When plants grow too large in this tank, I just trim them out, and take them to club auctions or sell online. Farm tanks also let you truly use only the plants you want in an aquascape, without feeling the need to cram a plant into the aquarium just so you don’t lose it. I have no idea how many different species of plants are crammed into this tank. I’m convinced that if I had a 1000 gallon aquarium, I’d somehow find a way to fill it with plant mass. The biggest challenge is ensuring that no single group of plants shade out others, as it’s easy to lose track of what’s growing where. Nevertheless, I highly recommend keeping a farm tank of some size as a way of improving the aquascapes in your other aquariums.

It’s amazing how something that I can describe in a few sentences above can take so long to implement. It was basically an all-day project, and a two-person job to actually move the tank. Then, after I got it setup, the Amazonia that I scraped off the top was so muddy that it turned the water into something resembling milk. After countless water changes, the water is finally clear, but there’s no aquascape in place. I’m going to use this tank as more of a farming tank to hold my extra plants. The blue-spotted sunfish and killies are still enjoying it as their home, however. I’ll post some picture of the tank itself after I’ve had a chance to fully plant and clean it up a little bit.

Immediately, I knew what had happened; the CO2 tank ran out, and dumped a ton of CO2 into the aquarium all at once. Right away, I pulled out my Python hose, and did a 50% water change. I also borrowed an air pump from another tank, and threw an airstone into the 40G. At that point, all I could do is wait and hope that I wasn’t too late.

I’m happy to report that despite some really dire looking fish, nearly all of the fish survived as of today. I only have one sunfish confirmed dead, and all killies are accounted for. I was lucky.

So, now the question is what can I do to prevent this from happening again? Well, two things come to mind:

1. I could add a pH controller to control the solenoid on my CO2 tank. If the tank suddenly started dumping, the pH controller would shut off the flow of CO2 once the pH dropped below a certain level. Unfortunately, this is not the cheapest solution.

2. I could attach a low-pressure regulator to the regulator I currently have. This would detect the low pressure that causes a CO2 dump, and vent that gas to the room, instead of the aquarium. The downside to this is that I already have a 3-way manifold on my regulator, which is pretty heavy. I’m not confident that the low-pressure regulator could support that weight.

So, I’m not sure what I’m going to do. At this point, I should have at least 6 months to decide before this could happen again. It’s not even a guarantee that it will happen again. That said, I don’t want to take any chances. Does anyone else have any alternative suggestions for what I could do to prevent this from happening in the future?

40G - Click picture for larger view.

The aquascape has changed a fair amount, as I’ve pulled out a significant amount of the hardscape I originally placed, largely to find room for a smattering of new plants that I needed to house. The Ranalisma rostrata has just about filled in the foreground. The right side of the tank is basically just a growing out space for various stems including Ludwigia sp. ‘Araguaia‘, Rotala sp. ‘Araguaia’, Blyxa alternifolius, Rotala sp. ‘Mini Type I’, and a Limnophila species. Due to all of these plants, I don’t envision this tank ever becoming a cohesive aquascape unless I’m able to setup a farm tank to transfer some of these out. The main thing, is that I’m quite impressed by the substrate sustained growth, with zero dosing. Comments welcome!

40G - Setup for about 1 month using earthworm castings.

Since setting it up, I have been doing weekly water changes, removing about 30-40% of the water during each change. I have been doing this because the tank has been having a terrible bout with hair algae. In addition, over the last week, I’ve been treating the tank with hydrogen perioxide, both to combat the algae, and as a preventative measure in case any of the fish I recently collected have any parasites. I’ve noticed a significant reduction in algae, although the problem continues. Despite the algae, I have witnessed fantastic plant growth over the last month. In particular, Ludwigia inclinata var. verticillata ‘Cuba’ has been particularly prolific. I trimmed right before this picture, otherwise it would be occupying the entire back right of the photo. Additionally, the Hygrophila sp. ‘Porto Velho’ and Ranalisma rostrata has been starting to fill across the foreground. I think I’m going to remove the Blyxa japonica from the right front entirely, as it looks out of place. Comments welcome!

Earthworm castings, Sand, 1 lb Clay

Vladimir Simoes’ method is basically just a mixture of earthworm castings and sand in a 50/50 ratio. As I did more research, I found that several of the past successful aquascapers that used this method, also used a clay source with a high CEC ratio. For this, I decided to follow much of the soil method by liquifying a pound of clay into the EC and sand mixture.

Dolomite, Potash, and Traces on bottom. Aquasoil around edges.

Also borrowing from the soil substrate method, I added a handful of dolomite, potash, and CSM+B traces to the bottom of the tank prior to adding the earthworm castings mixture. The purpose of these minerals is to provide a nutrient source while the neccessary bacterial colony builds up in the substrate to make these same nutrients available to the roots longterm. Additionally, my final modification is to reuse the spent ADA Aquasoil that was in my 40G previously as the top layer of the substrate. For aethestics, I used aquasoil exclusively around the visible borders of the tank.

Basalt and African bogwood

After adding the earthworm casting mixture, and topping it with the Aquasoil, it setup my hardscape. I’ve never really attempted a “mound” style aquascape before, so I decided to give it a try. I used a combination of the porous mossy rock (basalt) and African bogwood for my hardscape. I left plenty of space behind the hardscape to plant my background plants.

Finally, the planted scape is above. At this point, I’m not entirely pleased with the result. I need the plants to grow in a bit more, and I need the background plants to fully crest over top of the mound. I suspect that I may have placed the mound too far to the front of the tank, but am willing to let things play out for awhile to see how it looks. I basically just reused the plants that I had in this tank previously, but I did add some Echinodorus angustifolius ‘Vesuvius’, Pogostemon stellatus, and Ludwigia sp. ‘Cuba’ to the tank, removing Rotala rotundifolia and Eriocaulon sp. ‘Type 2.‘ My goal for this tank is to have a successful aqauscape while having the earthworm casting substrate provide all of the minerals needed so that I do not have to add supplemental fertilization.
