For any who do not know who Spartan is: he is 2.5 years old, 3 in February. I got him when he was an itty bitty dull orange approximately 6 month old betta. When he was 2 he survived a mystery poisoning, and since then has gone strong. Recently I found out his dark blue spot was really a tumor, and it has gotten a little bigger, somewhat on his fin. He is "hand raised"
docile to all fish, and doesn't even flare at his betta neighbor, Ghengis.
Anyways the issue:
I cannot really explain it... but he used to have a large underbite
Now, it isn't... I do not have a working camera sorry. But I'll try my best to explain.
Around his mouth is black, as his coloring always was there. Fully orange head... now, on his bottom jaw it's white. Not cottony, fluffy, or anything... but looks like the "skin" on the outside has deteriorated! Leaving what I believe is his teeth/jawbone exposed. It isn't hurting him any, as he eats his pellets well. Only changes, is we moved, and he is in the same tank just divided (ten gallon) and shared with Ghengis. He has of course been having a little trouble turning because of the tumor.
Has anyone else seen this happen? What it is from? anything I can do to either stop it, or make it more comfortable?
I took him out in a cup, and with my hand lifted him just a little bit so I could see his head. It doesn't look like cotton mouth... or any fungus... this started about a week ago I'd say. His bottom teeth used to be prominant (looked like a two tooth spikes :p ) but now isn't at all... He is also less interested to respond to me, and doesn't even care about much around him which I think is just because of age.
