i have had my 2 cresteds together for a while and i recently noticed they are both male. I bought them maybe 6 -8 months ago and they were about 1 month old. I havent noticed any aggressive behavior, but sometimes I do hear one running around the tank at night, but when i check up on them, they are both sitting there calm and far away. they even sometimes sleep together. do i need to seperate them? or would it be okay to give them a chance getting along? any positives and negatives attached with either choice? thanks
