iv got a simple question. i know hillies like to be with others of their own kind (so long as they have enough spaces to set up their own territories) so whats the minimum number i can get and still keep them happy?
Agreed, I'd go with 5 or 6, 20 gallon size tank minimum... the more you have the cooler they are, I've got 10 in my 29 gallon hillstream tank, absolutely awesome to watch.
