How Can I Help My Guppy

[Hannahmurphy]

My guppie has lost most of his tail since this morning when I was him. He seemed fine.

I have one rainbow gourami and five tetras in a 60L tank.

I suspect the gourami is doing it. Although, can fin rot set in that fast?

What shall I do to help him??

I would get rid of the Gourami, and do frequent water changes( with dechlor) and wait for him to recover. Is your tank cycled?

 

[Hannahmurphy]

Yes, tank's up and running a good while. All tests are very good with the water quality. Do you think it could maybe be tetras?

Thank you.

Nope, definatley the gourami.
