Hello. I’m curious if this is a sign of an internal parasite. My clown has been acting strange. Not moving much from one spot. She has stopped eating and has had some white poop. The male clown is perfectly fine and I’ve had them for about 2 months now. Could this be an internal parasite and how would they get this? And is there any medication that is reed safe. I don’t have a QT tank nor the space for one. Thanks in advance.
