One of my electric blue acaras bit the other one's eye during feeding today. The eye is still there but it looks like the outer layer (the cornea?) is flapping and is starting to turn white-ish instead of clear. Is there anything I can do? Would dips with aquarium salt help or just stress him out more from me having to catch him? Dose the whole tank with Paraguard? Would greatly appreciate any advice, they're my fin-babies.
