Colombian tetra/Bleeding heart tetra??

leopio · #1 ,

has anybody here ever kept them in a big group 30+. am thinking about getting some for my 5ft. 75 gal. long tank. they will be housed with a pair of Acarichthys Heckelii and a Blue Acara. My question is are they fin nippers?? even in a big group will they still nipp other fish? Same question for the bleeding heart. Am looking for a good size tetra that won't nipp on fins.

You don't think the Acara and Threadfin won't go after the smaller tetras?........Tetras kept in large groups generally keep their aggression among them selves, but may nip other fish occasionally.......There is no guarantee that any of the tetras won't nip.....I have seen Neons tear guppies up.
