Should/Could I add more?

[Drumachine09]

Well, my 55 looks kinda dull. Only two fish, a green severum, and a firemouth. Filtration is an AC 110 and a penguin 350. Weekly 15 gallon water changes.


Any reason why I wouldn't be able to get another south american or two? Suggestions?

You might get away with a single female Convict in there but not much more.

should be okay to add another fish, severums get large
