Fish Fanatic
Hi all, I have a Oscar with what resmbles like a wort or something on the left side of his bottom lip. it seems to grow then reduce in size then grow again. He is very active and has no trouble eating etc, I perform regular water changes and my water stats are as follows
Ammonia - 0
Nitrite - 0
Nitrate - 40
PH - 7.5
Temp 27
None of the other fish have anything like this in the tank. I'm wondering when I had a large red parrot fish, who has sadly now passed away
he used to pick on and lock mouths with the oscar, maybe it's an old wound witch just won't heal ?
Any advice on this very welcome
Thanks.
