blenny parasite

[johnfallon135]

my blenny swims in a awkward fast motion sometimes smacking itself off rocks I think he has some sort of parasite that I can't see I'm thinking of dosing prazipro in my display tank. should I be using prazipro and in my display tank?

Research Cryptocaryon, Amyloodinium and maybe Brooklynella. Besides rather rare parasitic copepods those are the usual suspects if a fish is "scratching" itself. Cryptocaryon (ich/ick) is usually the most likely culprit.
