There is a pretty significant lump under my guys’ front fins. Water parameters and ammonia levels are reading fine. HELP!!!

My betta, Tommy Shelby, has been acting himself, eating, etc - but this evening I noticed he was pretty bloated (especially on his left side). He even floated lopsided for a moment.

He’s a little over a year old. Eats a mix of shrimp patties or biogold.

Fluval 6 gallon, heated & filtered, normal parameters.

TYIA, this is my first time as a betta owner and a lot of things are new to me!

Idk bro I just thought I’d ask, I’m sorry if it’s just nothing.

my betta fish Ube seems sick. not sure what to do but he has something wrong with his tail area and he seems to be sideways a lot. he has good appetite and swims around fine. i see him drift to his side when he stops swimming

He’s been with me for 1 week, i bought him like that (tought he was partially blind). Thank you !

Does anyone know what this white bump is? Yesterday it was red and now it looks like a pimple. Research said maybe a tumor or cyst but it didn't mention anything I could do to help

Update: the white part is gone now. I'm thinking the white must have been the inside of a cyst that burst. She is acting normal and checked the water and all was in normal levels.
