Fin-Nipping *UPDATE VIDEO OF FISH*

[Flatcoatluver]

I have 1 red eye tetra, 1 black skirt tetra, and a mixed fruit tetra. Should I take them out of the guppie tank?

Sorry I don't know anything about community tanks. I have only ever had feeder guppies,goldfish and bettas.

I have heard of black skirts being rather aggressive, but from experiance, I know thats not always true. I have my black skirt in with one guppy and they're perfectly fine together.

Maybe just watch VERY closely to see who is doing the nipping. If its just one fish, it might be best to separate that one.

You need to just draw up a chair and see if you can spot anyone nipping - or even chasing.

If you have any stress coat, put a squirt of that in with female.

Hate when this happens. I've had it occur, it is SO frustrating.

I do NOT think it has anything to do with feeding.

Thanks everyone I will put some stress code in there with him. He acts completly normal but his tail is really chopped up. I will see if I can get a clear enough picture of him.

Here is a video for them.

Platys and tetras are known for fin nipping. Tetras are also schooling fish. In the absence of a school, they can become nippers due to stress. You really should get them a few friends. 4-5 of each type of tetra is much better than 1. Platies are just plain aggressive, but they aren't schoolers. Don't get any more platies.

I could not see your video, but mixed fruit tetras are injected with dye. This process results in pain, occasional internal problems, and sometime death. The fish lose their color in a few months. Often it reduces their lifespan by half. I'll assume that it is a white skirt tetra with dye, as I can't see, so it may or may not school with other skirt tetras.
