Blue Tang in a 4ft?

[timfillo]

I had purple, tomini, hippo and nasso in 75 gal. All were babies 0.5 - 2” when I bought them. I Planned to move to a bigger tank soon but they had to spend 2 years before it finally happened. Never had problems with aggression and only nasso looked uncomfortable sometimes. Hippo is the biggest but spent 80% of the time hiding in crevices. Tomini was always busy picking rocks. The only problems were keeping parameters and frequent water changes. Fed them with frozen two times a day, lettuce and pellets 4 times a day via feeder
