Is my albino cory dying?

Question

All my fish have been floated.

Answer 1

Corey cats and other fish need aquarium salt its 1 tablespoon per 5 gallons.

That or he's moping. Most fish will.  Mainly oscars, though.

Answer 2

It sounds weird but not like a disease.

Answer 3

sounds like he is stressed a lot. he may give off slime residue and keep doing the sidways thing untill the stressor stops. there is little you can do for him but just try and make his life easier.

did you just plop him in the tank? or float him?
