I changed the water today in my 29 gallon with my small red belly and small pacu in it and noticed something ackward. I had drained the water and was refilling it with fresh water and I noticed my P and the pacu were leaning at a 45 degree angle. I thought it looked weird and they seem to be doing fine now. Anyone else had a case of leaning Ps? Just wondering if my fish are strange or if that's a normal thing to have happen.
