Hey i need help, i think my baby fahaka puffer i recently got has ick? Hes about 2 -2 1/2 inches and hes been breathing hard/fast and sitting on the bottom of the tank, he eats fine but only swims around when the lights off. ive seen him scratch his sides against some rock decorations in the tank and when i was hand feeding him shrimp he would like ram my fingers and rub his side on my fingers. Is this ick or something else?
