When I came home from work today, one of my zebra danios was dead on the bottom of the tank and my bully gourami was eating him !!!!!!!!! I am thinking of taking the gourami back. I am pretty sure he was attacked by the gourami because my water parameters are perfect! 0/0/10... what should I do? Should I try the breeding box and put my gourami in it (because he is also harassing my other gourami) or should i just say two strikes is enough and get another danio and a couple of oto's in his place?
