Hey guys so I have a new baby serra. I believe he is a Rhom according to the guy I bought him for but he is to small to tell atm. Anyways. This is my first piranha. He eats great for me, usually takes 2 blood worms in the morning, afternoon, and then again at night. Anyways he has a lean. It is not always there but every now and then he will be leaning sideways in the water, instead of siting in the water column and being completely vertical. I hope that makes sense. Is this normal?
