One month ago, I acquired some reef aquarium inhabitants from a person exiting the hobby. Seeing as the livestock had been in the aquarium for over a year without new introductions according to the individual. I decided to forgo the standard prophylactic treatment for corals and fish, instead isolate all livestock in a dedicated 220 gallon aquarium. I really didn't want to unnecessarily stress the livestock by subjecting them to treatment if not required.
Fast forward a month, I have noticed a steady rate of regular flashing and yawning with all fish (1-2x per hour). Not increasing or decreasing, respiration rate, overall behavior and feeding normally for all fish.
Suspecting flukes, I preformed a freshwater dip to diagnoses, results where negative for Neobenedenia on 4 inhabitants. Preformed a skin scrape on 3 inhabitants, gill biopsy on a wrasse all clean under microscope. Did I simply miss the flukes when I preformed the biopsy?
Could free floating particulate in the water column or stray voltage explain the flashing and yawning?
Considering praziquantel is rather coral and fish safe, was considering dosing the aquarium at 2.5ppm (3 times with 7 day interval). The aquarium does have a population of bristleworms, snails and crabs, will these all be wiped out?
