issue with naso ... help

[cav~firez22]

they are all fed Brown, red & Green algae on a daily basis. But i will start adding the garlic to his foods

knock on wood, no i have not lost anything from this tank in years. The naso & powder blue are the newest addidtions. there was a little scuffle for the first day, but now they all seem to get along. except the clowns. they attack anything that goes near them...
