Hello everyone.
Just wondering if anyone knows what this could be? I kept Gourami's for a while now & this is the first time I have seen this. None of the other fish in the tank have this, so not sure if this is a parasite or some kind of tumour?
Would love to hear from others on this, I will put him to sleep if this is something that can't be cured with the usual remedies.
Thank you.
