Can someone tell me if my red devil is male or female? He/She has been moving rocks in the corners off my tank, has two dug and digging another. he/she is also getting very territorial and chasing away anyone that goes near the corners. Ive been watching it and it does this weird shaking when over the holes, any ideas why? thanks
here is a picture. male or female?
