So i have a hi fin red banded goby who keeps going in where my pump and heater are located in my fluval evo so when i did my water change i tried to get him out. Of course he jumped and landed on the floor. Hes so tiny i picked him up and he bit and hung onto my finger. ( they have teeth) lol. But it helped me to put him back in the tank since he hung on. I thought it was so funny but now he went back there again so i figured i just leave him there
