the fish in my predator tank are slowly getting covered with tiny white bumps. iv tried treating for ick but it keeps getting worse, my filefish's eyes are getting covered. im at a loss for what it could be, a local lfs told me velvet disease was going around but i cant find much on it and im not sure what it looks like. they are too tiny to show up on camera. could this be ick or is there something else i should be treating for?
