I have a 30g Tetra tank, in it are 4 Serpae, 3 Lemon, 2 XRay, and 2 Rosy Barbs.... I also had 2 Bloodfins.... They killed one, today I came home from work and found the mouth bitten off the other Bloodfin.... does anyone know who the culprit could be? I have taken the Bloodfin out of the tank, and put it in with the Mollies, it doesn't have a mouth to kill anything... will it die, or can it's mouth grow back.... I will get some meds for it, and put it in it's own tank if that will help it.
yep...it's the serpaes alright...meanest of the entire tetra family..(that includes piranha)take them out of the tank and hang them by their tails and throw rocks at them.
they are a really pretty fish.. it is too bad they are so mean..
