Hi, i have a tank of guppies neon tetra cardinal tetra glow light tetra albino widow tetra serpae tetra ember tetra..... now i have some fin nipping going on in my tank originally i thought it was the widow tetra causing it so they got moved to a seperate tank and it doesnt seem to have solved the problem so do you have any idea who the culprits are? My main tank is 200l and it has rocks and plants theres plenty of space and the fish are schooled in 6's and multiple feeding spots. Its my neon and cardinal tetras that are taking the brunt of it all. Any help would be great.....

I imagine that it's the serpae tetras. They are known for being nippers.

Thank you I will relocate them to the tank with the Widow Tetras then.
