green marble sick?

[slamster17]

i dont know whats wrong with him, i first noticed he was resting on the top kinda crooked then when i went to feed everyone he would eat a bloodworm spit it out try to attacck the tank sides and then hed go vertical. i did see him eat one bloodworm. i did a water change yesterday and i dont think its the water because even the fish i accidentally dropped on the floor is perfectly fine. i treated with salt stress coat and silver.
any ideas whats wrong with him?

Thanks

Sounds like a swim bladder problem. Try fasting him for a day or two and see if that helps. Then offer him a thawed frozen pea. If he's constipated (which often affects the swim bladder), then that should clear it up.

It could also be a bacterial infection causing swim bladder problems, so if you have any tetracycline or Maracyn (1 or 2) on hand, get it ready in case the fasting and pea don't help.
