Whats Killing My Tetras?

[tetra problem]

Hello. Can someone help me. I have a large tank with Rosy barbs, clown loach, guppies, dutch rams, indian banded gourami, black phantom tetra, copper harlequin a plec and cardinal and neon tetra.
Something in my tank seams to be nibbling at the fins of the neon and cardinal tetra and have already killed 3 neon and 1 cardinal.
Any info will be greatly appreciated.

Hi,
I have known of several occassions when Cardinals/Neons have been kept together and usually the Neons are killed> an 'expert' guy at shop said that they will fight each other and more often result in the whole of one group being killed.

>It's not scientifically proven, but it could explain what is happening in your tank as I don't think any of your other fish are known for attacking Tetras.

May be only add more of one of them groups of Tetras, if u want more.??

it's probably the rosy barbs or clown loaches. Neons and cardinals live together in the wild and are fine together in a tank.
