I have 45 gallon fish tank with 5 parrot fish in it I had one parrot fish with worm like things coming from its gills now another one has it what is it and how do I get rid of it? Please help
This is likely one of a few gill parasites. Would do two rounds of prazipro which is the safest & most effective way to treat. In a case like this where you can see them sticking out of the gills the two courses is best to assure the eradicaton of the parasites. Keep us posted
