It’s been about a month since my last update on this tank. I recently pulled out a large number of plants for the GWAPA auction, harvesting plenty of Utricularia graminfolia in particular. I’m pleased that the tank is growing well, despite measuring 0ppm nitrates yesterday (prior to dosing more), but some parts are growing out of my favor. Largely, the Anubias heterophylla on the right side is getting a bit unwieldy.

Also, the Pogostemon stellatus in the back right has gone in and out of looking great to looking like crap. So, I got some Ludwigia inclinata var. verticillata ‘Cuba’ and Eriocaulon sp. ‘Type 3’ at the last GWAPA auction that will hopefully replace the P. stellatus in the back right. My problem is that I haven’t found the best transition plant for the right mid ground. On the left, I have the Utricularia graminfolia in front, with Hygrophila sp. ‘Low Grow’ and Crypt. affinis behind that, stepping up to Blyxa aubertii. That’s a nice transition. On the right, it’s the Utricularia to Crypt. willisii to the stems. Unfortunately, the stems usually look like crap after a trim, messing up the transition. I’ve thought about moving some Eriocaulon sp. ‘Type 2’ over there, but that plant may then be repeated too closely together.

Maybe I’m thinking too much?

I noticed some increased fin flashing activity in my 40G tank, and decided to try and capture a few good shots of my Apistogramma sp. ‘Rotpunkt.’ Some of the shots are better than others, but there’s no doubt that these are some pretty fish, whose colors especially pop under the new 2x96W lights!

A. sp. ‘Rotpunkt’ Non-Dominant Male. Not nearly as impressive, huh?

I should have used a flash above the tank to shoot at a better quality ISO, but I always end up spooking the fish in order to set that up.

Thanks for looking! Any comment/critiques are welcome, as always!

Remember back in the summer when I brought home the wild Jewel cichlids from Florida, and they immediately spawned? The fry were so tiny back then.

Now, only about 6-7 months later, the then fry, are now nearly as large as the adults. What may be even more amazing is that the two parents are living peacefully with their 2 remaining children in a 20H. I gave the other fry away when they were only an inch or two.

While not quite as large or colorful as their parents, they are starting to look fairly decent. The “jewels” are becoming more visible and intense on their face, and their body is staying a nice dark cobalt color.

I imagine that they won’t ever look as good as their dominant parents until they move on to a tank of their own. I’m trying to maintain the peace by regularly feeding them large meals of blackworms, spectrum, or the occasional feeder guppy. They’re voracious eaters, but don’t seem to fight each other for food.

When we went on our short weekend trip for four days, I didn’t line up a special feeding regimen, however, and they didn’t beat each other up, so I must assume that they’ve worked out a living arrangement amongst themselves. Hopefully that’ll last for a long time. I imagine that if they ever spawn again, trouble might result. Until then, they’re a fun, and personable group of fish that seem to recognize me, and watch me from the right corner of the tank, whenever I’m in the room.

I’ve been growing Ranalisma rostrata in my 40G tank as the foreground for some time. When I originally setup my 20H, I decided to also plant it in there. As the 20H progressed, I realized that I had too much light, too little CO2, and too little desire to maintain the tank as I really wanted. Therefore, I removed the 55W PC light from overtop, and replaced it with an ordinary 15W fluorescent light strip. Over the past few months, besides being considerably darker than it was before, I’d noticed a huge change in the form of the Ranalisma rostrata in that tank.

Witness how the grassy plant looks in my 40G. Compact growth, overlapping each other, where each blade is thin and relatively uniform.

In my 20H, the growth is quite different (below), with blades more resembling a sword plant, than grass. The blades are longer and the growth is much slower. I suspect that the plant is sending out broader leaves to try and soak up more light since less is available. The color is also slightly different, with the broader leaves being a bit more pale, with a yellowish tint, where the regular form is a bright green.

I’m sure that this same phenomenon is present in a wide variety of plants, which is why it’s difficult to say exactly how a plant will grow in another person’s tank. I’m often asked at GWAPA meetings whether a plant is high light or not. In general, I can usually only respond that I’ve only ever grown it in high light, but that they should try it out, and see if it survives in their tank. Now, I can’t even guarantee that it’ll look the same!

On Saturday, GWAPA kicked off 2008 with its first meeting of the year. Dave had been working for months on getting his basement ready for us to aquascape his newly installed 180G aquarium. Dave is doing a soil-based substrate, using mineralized topsoil with a few added nutrients, as his base. It’s capped with a layer of 3M Color Quartz pebbles.

Of course, the hardscape is made up of our porous mossy rock and manzanita, both from California. Being such a large tank, he’s trying to keep it manageable by using lower maintenance plants, such as crypts, anubias, and java fern. There are some other exotics, such as Pogostemon stellatus and Hygrophilia sp. ‘Low Grow’ as well.

Prior to scaping, Dave gave a nice presentation about the Golden Ratio, using yarn, strewn across the front of his tank to demonstrate the principle. As you can see, he’s applied the rule of thirds when setting up his hardscape, as well as, using asymmetry in terms of the size and numbers of rocks in each grouping to make the hardscape appealing to the eye.

We had a huge auction at our meeting this month, as well. I brought the most plants I think I’ve ever brought to a meeting. That’s what happens when there’s almost 2 months in between meetings! My tanks are looking a bit bare right now as a result.

Thanks to Jeff U for the meeting pictures!
