Well when i have to feed dwaine (my mbu) i put some dry food in there and then try to hand feed him some prawn, mussle, and lancefish on his meaty feed nights and drop em near him as theres a lot of other nice sized fish in there which pinch his food and on the other day when its his frozen food day, i get a wedge of bloodworm and hold it in the water for him to swim around and eat and a few of my loaches and cichlids eat it, also my flagtail he loves to hand feed. But a few times hes lunged and just missed my fingers and well today i was too busy watching the other and didnt see that he had jumped and bit my little finger! :O clamped hard and quickly let go, didnt bleed strangly. Been bit by bigger and hard, but the hardest bite i think was by a 18" Giant gourami, didnt draw much blood but really clapped down hard! I hope that my african tiger doesnt start biting lol.
