so i just got a new glofish tetra and last night he got caught on the filter. i believe he got stuck between the filter and the rocks because the filter is too low (should i move it up or put it right into the rocks?) i turned it off as soon as i realized and he swam away but now he has a slight curve in his body and seems to be off balance/ have a hurt fin. he just is floating around mostly and he cannot get his head up to eat. he can swim but not as fast.
iím a very new fish owner and idk what to do
