So there is a special kind of fish that I can't get at my local pet store. And they can only be obtained by the local bait shop, FYI its tadpole madtom or stonecat either of the two. And I want to add them to my fish tank. And I already know that aquatic fish and wild fishes should not be added together. So I have the madtoms in a control tank for now, and I am not sure at the moment if the madtoms have any parasites or diseases on them. Since madtoms and stonecats are schooling catfishes, it should show that there healthy if they school. And at the moment after settling into their control tank, bucket, they are already showing signs of schooling which should provide that they're healthy and there coloring is not to far off from each other so they seem pretty healthy from my standpoint. Any tips on how to remove any further pathogens or parasite that could be floating in the water that can't breach the little cat's skin but onto other fishes? All thoughts would be helpful, thank you for your time.
