well i put m male and female together in the males viv... he stalked her did the vibrating thing... and then went for her neck she turned around and bit him and like shook his head... i grabbed him and removed him =[ is there a chance she'll ever wanna mate she was alone since she was hatched i got her a few months old 7 years ago... and she never mated is it shes too old to ever mate if so ill get another female and put her and the male in the 20L and put her in the males 10g since the female is in the 20l and male is in the 10g and i took him out so they wouldnt fight
