I am currently purchasing an innovative marine 80g with the dimensions of 47x18x16. I created a stocking list but I’m not sure if this is too many fish.
2x black ice clownfish
Orange back fairy wrasse
Sand sifting goby
Flame hawk
Tomini Tang
Green mandarin
3x anthias (undecided type)
Purple Tang
Powder blue tang
Copperband Butterfly
Cleaner wrasse

. In this case I think it is. At least a couple may bully some of the others, and the purple tang and powder blue tang this size will likely be an issue as they grow. I however, had a 5 foot tank - a little deeper and taller with 3 tangs - and no problems (and a copper band). Hope this helps - good luck with your new tank
