My first tank, when I was very uneducated, came with a Chinese Algae Eater, whom I'm very attached to. He's actually not been to bad so far, even though he's close to 6". I currently keep him in a tank with guppies, and he's fine with them. They'll even nip at him if he's being annoying! They know not to go in his cave, or steal his food, and although he occasionally chases them off, he's never actually laid a (fin?) on any of them. He's even fine with the guppy fry.
However, he does display more aggression than any of my other fish. I know he's continuing to grow up, and will become more territorial and aggressive, so I need a long term plan.
Would he be okay in a community tank if it was large enough, and heavily planted? Has anyone heard of them working well with dwarf puffers? I plan on setting up a puffer tank in the next month or so. How about ropefish? That's another kind of tank I've been considering, and if he got on well, that would be another reason to do it. The last option, would he be alright in a 10 gallon by himself, or is that just too cruel? Will he grow too large for that tank?
Sorry for the novel. Any help is appreciated! Thanks!
