Bumblebee gobies are so funny! Yesterday I added 2 of them to a 6 foot tank that has 4 bristlenose and 9 kuhli loaches. Within 15 seconds of releasing them, one of them decided he was boss, and started stalking each of the unsuspecting kuhlis. He would pull up alongside like there was nothing going on, and then give them a little nip on their tails!! He chases the other bb goby around the tank- when I say 'chases' picture the OJ Simpson pursuit. Slo-mo
Not sure the 2nd one is going to make it as he is underweight. I'm going to get some live blackworms and see if he'll eat those.
It's so cool how the other one patrols the entire tank though. Little tough guy. My own Napoleon!
