I have noticed some weird behavior from one of my albino CF's. For the past month or so one of his hind legs seems to "float". Before it was every now and then, and usually after feeding. So I thought he had an air bubble or something. But now it seems like its almost all the time.
His front half stays normal but it looks like someone tied an invisible balloon to his back right leg. Any ideas what is causing this? He is in a gallon and a half plastic aquarium and about 6(?) months old now im guessing. I feed them frog bites and blood worms. And the occasional small cricket.
Any info is appreciated thanks!!
