hello i have two chinese fire belly newts male and female. The male seems to be quite grumpy towards the female, at first they were nice to each other when i got them. And the male would try n seduce her etc. she wouldn't have it. however now, whenever the female touches the aquarium floor he gets all annoyed and tries to bite her. so now she stays on a piece of wood near the surface and he guards the floor. why is this?
