Interesting tumour or something

Grant and I had dinner at The Mud Castle in Upper Moutere last weekend. This is one of the bathrooms...

I noticed one of the fish had carp pox but another had a tumour-like growth on its head. I have never seen anything like it. It appeared otherwise happy and healthy. Anyone seen a growth like this?

Yes I have seen it before on one of my ex paradise fish :( . I wasn't as big but it didn't eventually kill him, he would be swimming along and just stop for 10-20 seconds then start swimming again as happy as ever. I never did find out what it was, I tried treating it with nearly everything under the sun but i just continued to get bigger.

it is a wound that got infected, and is now healing on its own.... slowly.

It looks like an old wound/ulcerating tumour with necrotic (dead - black) tissue. I wouldn't have hope for the fish though - with necrotic tissue and such a large wound, the fish is likely to become septicaemic (toxic with bacterial overload). :(

i have a goldfish with a similar tumour in the same place except its just white hasnt got any bigger for a while and doesnt look infected ane ideas how to get rid of it?

If it is a tumour, and the skin has opened up, it is unlikely to ever heal on its own. If you wanted to get rid of it, you would need to cut it out with wide margins around the cancerous tissue and ideally suture or bandage the remaining wound so that it heals and forms a good scar. Of course for the layperson, that is near impossible with fish - especially in that location and since the water is full of potential pathogenic contamination....although a good antibiotic would help.

If it is some other type of wound not related to a neoplasm (tumour), the likelihood of healing is dependent on the fish's immune response, bacterial contamination and the size of the wound. Removing some of the dead tissue can someimes stimulate the wound healing response but it can also expose the tissues to pathogens or cause lethal bleeding amd fluid loss.

If it were me, I would keep the water as clean as possible, feed the fish very well to promote a good immune system, minimise stress by allowing a good amount of rest and other environmental enrichment, and hope for the best in terms of healing. If you wanted to be more proactive you could add antibacterials or antiobiotics, but take care as either can cause stress so you would need to be very consistent with your treatment regime in terms of follow through.

Just my opinion, but I am not a fish medicine specialist.
