Hi, i have a pair of pictus sharks, i have noticed one of them seems to grown around the girth quite a bit, + also i have seen the 2 of them wrapping there bodies around each other like there playing but i think they may be getting ready to breed or am i wrong, if i am correct in thinking they may breed what is best solution as they are in a tank with angels, severums,+ gouramis any help would be great.
