Ok after I did about a 40% water change I noticed one of the baby Leich's was swimming funny. It looks like its back is a little kinked and swimming a little funny. Its in a 20gal tall with another baby Leich, they are divided. I moved him to the other side with out the return on the HOB so their would be less current and added aquarium salt. I moved the normal Leich to the side with the return of the HOB. I have the lights off as well in the tank. Any suggestions on what else I should do? Do you think he will recover from the kink in his back. They are both about 2.5-3 inches.
