I had mine in my 94 gal tank for 5 years untill my tank was wiped out by a defective heater.
some key requirments are lots of O2, so oversized skimmers run 24/7 work well for this, 0 nitrates is another important thing I found out. the water must be very clean. as for 6 foot tank I will agree to disagree on that one. most of these tank sizes came from when people used to stuff a 100 gal tank with 200 lbs of rock, which resulted in almost no swimming area.
I had 120 lbs of rock in my 94 gal tank aranged in a manor that 3/4 of the tank was open area. so my tank was 3 foot long, 2 foot wide and 25" tall. I never had any problems what so ever, no ich, no nothing.. I bought him.. took him home, dumped the bag out into my fish transfer strainer and put him in the tank. I did ballance the bag water to my tank first.
I have never been a fan of quarenteen tank, I think they do more harm than good, and I never put any other water in my tanks.
there was a good write up on them I found 10 or so years ago that atrubuted 90% of the problems people have with them were related to nitrates in the tank water. a low level isn't good enough, you must have none. the areas where they occure naturaly are not nitrate or nutrent rich area but rather the oposit.
for food, I fed nori, some expensive pellet food, frozen krill, and the ocasional treet of baby brine shrimp.
they are classed as a harder fish, but if you have a mature tank with pristeen water, lots of open swimming area, and lots of flow you should be ok.
as for tank size.. I leve that up to the individual, but I myself having been sucessfull before, wouldent be oposed to put one in a a tank as small as 75 gal depending on the lay out.
