Hey guys I wanted you all to know about my porcupine puffer fish, for some time now not only has he not been eating much, but he also damaged his left eye, and his tail fin is rotting away. Despite all this though he still swims around and is still responsive when I wave my hand at the tank. Is it possible for him to make a full recovery (fully restoring his left eye and regrowing his tail fin) or is he too far gone at this point?
