this morning when i woke up i saw this thing on its anal, i thought it was just weird poop. but when i look at it at night, it's still there and he DID poop (black normal poop) with the thing still stuck there and i think i can see blood on it too. should i get him out of the tank as it will affect my other fishes or he will be fine? but what is it it's SO WEIRD AND SICK like his bone is coming out from his anal
