So as long as I upgrade in two years I can make the blue tang, white tail, and yellow tang work? Would the yellow and purple not work if they are introduced at the exact same time? I really love tangs! I would attempt to get them all at the smallest size available.I really like your fish options though I’m guessing this is a dream list not the one for your current system?
I don’t want to choose for you which ones would work so why don’t you pick a few of the fish you are serious about from your list compared to the ones on your current list and we can talk which ones will work for the set list.
Purple Tang you could house for a few months or a year but it would be the only Zebrazoma tang in this tank and maybe even the only Tang in the tank.
Blue Tang gets too boisterous big and active but can be kept in your display for a few months until it starts reaching that 3 or 4 inch mark. Also the only tang in the tank
Achillies is a no go unfortunately for this tank at any interval but could work well in your Dream Tank.
None of the 3 Tangs should be kept in your sized system for 2+ years just as a disclaimer.
Otherwise I really love the copperband, puffer, dottyback, and wrasses.
My original list is what I’m sticking with other than this last fish. I do plan on upgrading in about two years though.
