My swordtail (fish) is swimming in circles upside-down, and can't seem to swim straight. What could be the problem? :o
The only possibility is that your swordfish is g*y, because it can't go straight or anything
Your swordtail can behave this way if it is suffering from any physical injuries. You should get a well informed vet to inform you if this is normal hence advice you o how to rectify it.
Sounds like he's dying, sorry to say.
