I have a friend who brought me his male albino bristlenose that was lethargic. I put it in a bare 20 long with some caves by itself and a seasoned filter. It would still swim some but wouldn't run from a hand or net. Well last night I noticed he was curled in a strange position, it would still move around but would stay in that position. I added some aquarium salt last night hoping it would help. This morning he was out but still in the strange position, any ideas?
