Colombian Tetras aggresive?
Well recently I went to petsmart and purchased 6 neon tetras and 4 colombian tetras for my 29 gallon. Its well filtrated by a Filstar XP2 and is well established. It has another school of 6 rummy nose, gourami, and an adult angelfish.
Since then out of the 6, 2 have died from the neon tetras and every other fish has been fine. The 4 neons school with my rummys constantly and the two new ones I added today school with them as well but then the 2 new ones died with bites on their body. I haven't gotten to see who it was, but my though is, is that it is the group of 4 colombian tetras. I didn't know anything about them but they were labeled as community fish. So now I have to go back and REPLACE the 2 neon tetras I already replaced... lol
So should I just return the 4 colombian tetras (costed 80 cents [black friday deal), get my other two neons back, and replace the 4 colombians with something else?
I don't see a problem with my angel and neons because he is pretty passive and only gets in small chases with the gourami so they keep each other busy and he doesn't worry about my schooling fish (rummys and neons)
I need some feedback, im pretty stressed about my FISH believe it or not haha, thanks guys.
