my tetra is missing its tail

[ratsinmyfreezer]

Wasn't like this yesterday. Have 5 tetras together a



nd never really noticed any bullying.

What should I do?

I would assume someone got feisty with him if you hadn't noticed a change before. WCs should help

So long as it is only the fin missing, he should be able to grow it back with some time. Very clean water will help. If you can get some, Indian Almond leaves will help too. They will colour the water, but that is easily dealt with later on, after the fin heals.
