you aint gotta worry about them biting u the only cichlids that do that are dovii, managuenses, red devils, umbees and buttikafri. there are a couple more but green terrors arnt one of them oh and feed them good pellets like hikari gold, and try aglae wafers and give them treats like krill, worms, crickets, shrimp, and every once in a while give them some QUARINTINED feeders. ur terror should come out like a champ. member to feed him once a day not too much or it will mess with their digestive track remember in the wild they are lucky to come by food once every other day. so try to stick with once a day no matter how much he begs u. BTW fish can go for a couple of weeks without eating....BUT DONT TRY IT THOUGH!!!!!!! OR I WILL PERSONALLY COME THERE AND SLAP U!
j/k
GOOD LUCK
