Keeping Multiple Tangs
I have four LARGE tangs in a 150 long reef; Yellow 6", Purple 5", Regal 7" and a Naso 7 1/2" (not finished growing). The only issue I have is algae. I was wondering why I had it. Then as I was pondering this while looking at my tank, my big blue swam center stage and relieved its self of the day's nori feeding, TANGS ARE POOH MACHINES! If you are going to have tangs, make sure you have really good filtration. Other than that there seems to be hardly any aggression. As far as the ICH goes, a fat happy fish is a non-stressed fish = no ICH. Fish compete for two things, territory and food. Give them enough space and they will work out their territories, just make sure the are fed WELL and you shouldn't have any problems. I also have a Scopas 4", Yellow 4" and A Sailfin 8 1/2" in a 150 high. No ICH there either. Feed well and be happy,
