hello everyone , i've been obsessed with powder blue tang lately , but i have a few questions about getting a one , im concerning about my old tangs that i already have ( 1 purple , 1 yellow and 1 naso tang ) . Powder blue tangs are most likely to get caught to white spot , will my other tangs get caught to it too . My old tangs are eating really well and they are very healty , but it stills concerns me . Also will they beat powder blue when i intruduce him to the others ?
