Turning off the lights, or covering the eye with a removable "cup" of
some sort might be a good idea, if it is practical with your study
species... I'd be skeptical that blinding the fish chemically or
physically wouldn't lead to many experimental artifacts (behavioral
changes... unless this is what you're after). A humane method may be
simpler, cost you less in red tape, and... it's humane.
