Jardini Help please!

I have a 14 inch Jardini. Had him for several years water conditions have always been the same. Recently stopped eating and formed several bumps on his head/ would just lay on the bottom. Seems to swim more when I turn on the tank light. I do water changes every 2 weeks/ temp is good/ plenty of filtration and air. No other tank mates. any ideas what the bumps could be? appreciate any help




Thanks!!!!!

Just eyeing he may be bigger. I'll try doing more water changes. I've kept him at same conditions never had any problems. He's in a 200 gal

I'll give that a try. Need to get some salt.

It doesn't really ever jump much, but he did hit the suction tube hard recently maybe scratched himself. Size wise he's longer than my forearm n pretty thick. Bump seemed to appeared pretty quick
