well I got a cory yesterday to put with my other two in my tank, I also got some bleeding heart tetras while I was there. Well today it seems the cory likes to school with tetras. If he gets seperated from the cories he goes to the tetras and swims with them, when they speed up so does he, it's really weird. When he bumps into the other coried again then he will school with them but he really likes those tetras. Has anyone ever had this happen or know why he might do that?
