Got my self a zebra moray and a greasy grouper in a 10 gallon connecting with another 6 gallon tank (these were my only left over tanks for quarantining) just dosed my first dose of praziquantel powder from fluke x, Ive currently run out of metronidazole, so is it necessary to dose metronidazole aswell? If it is, I might order some, though, it might take a day, is there anything I should know about taking care of these 2 fish? They will be going in a 150 gallon tank 60x24x24, how long should I treat them to make sure they don't have any internal parasites or flukes?
