I have a little bichir in a 10 gallon grow out tank (don’t worry 125 gallon is on stand by) and he just started freaking out he swims frantically around the tank jumping and swimming into things and then he just sits still for a little while and starts doing it again when he sits still he looks out of it he just breathes heavily and let’s the water move him a little sometimes he flips upside down and just keeps breathing but it’s not swim bladder problems because I’ve seen it before and that is definitely not what’s wrong with him… anybody got any ideas of how I can help him?
