We recently got a tang for our 36-gal FOWLR
tank. We pored over the fish compatibility tables and species habits, and settled on a Yellow Tang b/c it was the only one with min tank size anywhere near ours - 50-gal
IIRC. All the other tangs were listed as 75-180-gal
So far so good, the tang is healthy & active; hangs around with our coral beauty a lot. He/she does periodically do abrupt pitching actions that could be construed as frustration.
We have lots of LR
now; I hope that will make up for smallish tank capacity. Let's hope so.
I wonder if anyone has experience keeping tangs long-term in smallish tanks, and if so, what species.
Always interested too in what fish thrive in small tanks. I have dreams for a larger tank, but no time for it now - I'd have to build a custom size one for our space, along with stand & hood.
