Hey everyone so I found out my blue hippo had flukes and treated with prazipro 90% dose. He is in the tank with 6 other fish which have never shown signs of any illness..Today is day 3 and all my fish started flashing like almost simultaneously and I don't know if this is normal...they are eating alot and are swimming happy and my blue hippo looks almost perfect again..but now just all of them flashing starting today
