Update! Added More Fish And Still...aggressive Bullish Behaviour S

[mrvillicus]

Hi everyone,

Today I removed all of my fish from my tank as I wish to restock but I left two fish in there, im not sure on the species. Since they were removed One of the fish left over has been non stop chasing after the other one, theres a link to the video here http/youtu.be/Ww--pyfvPbk. Is this behaviour simply a male after the female?

Thanks Ben

They look like young myloplus fish to me. These fish like to be in groups and this behaviour is purely because of dominance. If you up the group, things should calm down.

Columbian tetras need a school 8+ generally best.

ahh that may explain it then, ive just picked up 2 more young columbian tetra and 6 small neon tetra and the big guys going crazy chasing the new guys everywhere, might consider removing him as I dont want too many tetra
