We’ve started to get some cooler evenings as we’re days away from the start of Autumn. Therefore, I decided to begin the process of shutting down my raised brick pond for the year by netting out my mosquito controlling white cloud mountain minnows and bringing them indoors.

I had put a dozen outside in the spring, but so far I’ve netted about 20 adult sized fish, and quite a few tiny fry (2-3 mm). I’m going to try to collect as many of the tiny fry as possible and raise them in an extremely densely planted aquarium inside. I love putting fish outdoors, as when I bring them back inside, I almost always multiply the number of fish I have, and the colors on the fish are fantastic from all of the live food they’ve hunted down over the summer.

All of these minnows are going into my 12G bookshelf aquarium, which has a large colony of orange-eyed-blue-tiger-shrimp in it, plus about 50 juvenile bristlenosed plecos. This is a low-tech tank without any CO2 added and minimal fertilization, but there has a noticeable increase in plant growth since I’ve added the baby plecos and minnows. I guess they’re producing just enough waste to spur the plants on.

The baby plecos are also progressing pretty well. I’m keep their small bellies round and full by feeding them a mixture of veggie pellets, with earthworm or shrimp protein foods added 1-2X a week. Of course, I just noticed a brand new spawn of bristlenose in my 50G aquarium, so I’m overflowing a little bit with these fish at the moment.

Nevertheless, my 12G bookshelf tank is becoming one of my favorite aquariums to sit and watch. The bottom is always moving with shrimp and plecos scavenging about, and now the white cloud mountain minnows are constantly active in the upper water column. Comments welcome!

I wanted to share an updated photo of my 12G bookshelf aquarium. The aquascape is largely unchanged since the last photo, but the hairgrass has grown in a little bit. I also went to the trouble of removing the equipment for this particular shot. Notice the pleco in the back left. I put those guys in this tank when they were only a few millimeters long.

I’m fairly pleased with this aquascape, although I’m not very happy with this Eleocharis sp. ‘Japan’ hairgrass. It just grows WAY too slow. Because of that and some beard algae on the rocks, I’m kind of getting the itch to rescape it. What do you guys think? Comments/critiques welcome!

About a month ago, I order my first rimless aquarium from Green Leaf Aquariums down in Florida. The aquarium that I had been eying for some time was their “bookshelf tank,” which is a 36″x8.3″x9.4″ rimless aquarium; dimensions that are unique to GLA’s product line. The alluring and challenging thing about these dimensions are the fact that it is such a wide tank, without very much depth to create a smooth transition from foreground to background.

Three and a half weeks ago, I decommissioned my 20L aquarium that was sitting on a wire shelf and began preparing to setup the new 12G bookshelf tank. Since rimless aquariums generally need more support than traditional designs, I built a small platform out of 2x4s and plywood to for the aquarium to rest on. For padding and aesthetics, I cut down a green yoga mat and laid it over the platform. Now that I didn’t have to worry about the wire-rack bowing and causing a leak in my new aquarium, I set out aquascaping it.

I decided to go with a minimalistic approach for this aquascape, consisting solely of a locally collected crumbly slate, and only two plants species – Eleocharis sp. ‘Japan’ and Blyxa japonica. For substrate, I combined several different bags of old ADA Aquasoil consisting of Amazonia, Africana, and Malaya, and set to work positioning the rock. I built up a prominent structure on the right side, leaving an expansion of loosely united pieces on the left.

Three weeks later, the Blyxa japonica is growing wonderfully, while the Eleocharis sp. ‘Japan’ is exhibiting the same slow growth that I’ve seen in other aquariums. That’s okay, however, as I really like the look of the three mixed Aquasoil types against the Blyxa background.

For filtration, I’m using a miniature ZooMed canister filter, and have a Hydor Koralia Nano running for added circulation. The tank shares a 20 pound canister with three other aquariums so it has pressurized CO2 running throughout the day. I’m very pleased with the aquarium itself, being a very clear, well constructed, and attractive unit. Comments/critique welcome!
