Well, the guy now has the small black spots on his body. Looks like black ick. I'm going to move this guy to my old 20g tank, but I feel so bad for him! He's been through it all.
i had that problem with my oscar when i first had him i bought him sick with ick and when the ick parasites went away it turned into pop eye bloat everything but i new he was hurting but it was better to save him then have let him die or killed him because its about 5 months later and hes fine..so id keep fighting try to find somethin with aloe in it to repair its fins i think theres something called melafix?? it smells real bad it stinks up ur house but it will repair them in a couple days i mean there bones will grow back fins and everything im pretty sure its sw safe my oscar looked just like that
