Can someone help me figure out what the heck my two Pacus are doing? They are constantly circling around each other and rubbing into each other, one more so than the other. I know they cant be fighting because they do that once in a while and chase each other. I also don't think they would be trying to breed either because they are too young, they are about 4-5 inches. I bought them together and they were the only two Pacus in the store tank since they arrived in shipment. I don't know how to sex them so if anyone can help me with some knowledge on these guys it would be greatly appreciated. I'm looking foward to hearing if these two are really that much in love with each other because honestly its quite cute how they are together. ;-) Thanks.
