Installed two 10g and a 5g under my 33L. Yes the long run of taking out that canister is going to be annoying but I think I have a method. This will be one of those projects I never let anyone else do because I am the only one that knows the proper order to do the things in so it all doesn't fall apart.
Anyway, 5 will likely be a shrimp tank soon and the others currently only house a single rainbow shark at the moment. They will be used to breed mainly down the road. The rainbows are sort of in quarantine but they are going into a year old 75 gallon and I want them to grow up a bit so they don't feel too small going in.
in each is a java fern or two, crypt undulata and crypt parva as well as DHG for the first time.
