I just bought a pair of clowns about 2 days ago. I realize that they're really new and are still acclimating, but 1 is doing really well, eating and exploring. The other stays in 1 spot, has clamped fins, seems to be doing jerking motions a lot and has stringy white poop. I haven't seen her eat yet, but it's only been 2 days, like I said. Should I take her out and put her in QT or should I wait a few more days? If I take her out, how should I go about treating this if the symptoms continue? I've read that stingy white poop is sometimes an indication of an internal parasite...what's the best thing to treat this w/ if the clown continues to not eat? There's no other fish in the main tank except her buddy who's doing very well. Water params: Nitrite & Ammonia = 0, Nitrates = 5ppm, SG = 1.025, Temp = 79. Please help!
