Baphijmm Posted April 17, 2022 Share Posted April 17, 2022 (edited) With renewed vigor, I attempt to revive a tank plan I started... probably back in 2018. At the time, Walmart was trying to get rid of the last of their BIG fish stuff, and that included 55-gallon tanks, discounted deeply at I believe 50% off. I bought one without a plan, and a tank stand to match. After quite some time sitting in a back room, I decided I'd try my hand at a biotope tank, and not just any--a Rio Negro biotope. Blackwater, beautiful fish shimmering through the surprising clarity of brown. Alas, a plant, likely a bunch of Amazon frogbit bought off eBay, brought the tank to a screeching halt--the plant had come with bladder snail eggs. In days, the tank was completely overrun. Blackwater is achieved through tannins from dead plant matter; as bladder snails eat dead plant matter, it didn't take long for their population to explode. Before long, all the live plants in the tank disappeared, also apparently on the menu. The bioload skyrocketed, and while several fish survived, even living to this day, there were quite a few deaths. I attempted many different things to get rid of the snails, none of them particularly successful. But, I'm trying again, with new material. The surviving fish in this tank are a small handful of adolfoi corys, and a similar number of cardinal tetra. A few weeks ago, I decided to push to making this tank work again, and to that end obtained a number of guppies. (These have already reproduced, which tells me at least one of the females was already pregnant when I got them. Which is wonderful! It's what I wanted to see.) This last week, I also got a bunch more cardinal tetras, having found them by surprise at a Petco of all places. I'd actually intended to purchase just as many online once I could find some, but this worked out rather nicely! Tonight, after having perused these forums for a while, I found an old post (actually from around the time I tried to set this tank up initially) looking for help regarding a Ziss bubble bio filter; the problem they were having with it was similar to a problem I'd had with mine (also in this tank, visible on the left side in the picture): The media always clumps up at the top, and the air flow seems to come out of it in fits and starts. Following the suggestions from that post, namely to take the whole thing apart, clean it completely, then verify the air hose is fully seated in the bottom receptacle of the unit, at the very least the media is no longer clumping at the top, but rather properly tumbling again. (The flow is still weird, but I'm sure that might need to be adjusted.) We'll see how long this lasts. Also, this was kind of a massive pain, took me upwards of half an hour because the media kept wanting to get in the way, so I'd have to keep dumping it out, fixing the air line, then pouring it back into the canister, hoping this time it wouldn't get behind the hose, or the hose wouldn't bend when I put the top back on, or the air hose coupler in it, or the external air hose to the coupler. Plans for next week include new plants (yes, from Aquarium Co-op, including an Amazon sword, a couple jungle val, micro sword, and Brazilian pennywort), and to obtain a few new fish for the tank, including some more adolfoi corys and a handful more guppies. (I wouldn't be averse to getting some more cardinal tetras too, if the Petco I went to still has them this week.) Eventual plans? I'd like to find some Apistogramma regani, and probably eventually try to get some discus (six, naturally) if I can get the snail problem taken care of. I'm also hoping to find some Carnegiella marthae (sometimes called blackwing hatchetfish); a local pet store chain in Albuquerque had one location that would occasionally get them in, but it was extremely uncommon. EDIT: How could I forget? I also want to get a small shoal of L183, sometimes called white seam bristlenose plecos or starlight plecos. Those are probably the most difficult of these to find, alongside the A. regani.
