[Delphinus]

I don't know. It's hard to say. I've seen happy triggers in smaller tanks, so you'd think it would be OK. I was just blown away at the crosshatches - until I saw this pair that was full-size, I had been dreaming that "one day" a pair would be my "showcase fish" in my big tank, but when I saw them, I honestly felt they were too big. That's not to say you can't get them smaller though, so that becomes a judgment call - do you get them and sell them (or upgrade) if/when they outgrow the tank? Or will they sort of stop growing (I've never really understood if that's a truth or not with fish). But this was with crosshatch triggers, which are not cheap anyhow (like, think $600-800 for a pair). But a pair of blue throats is considerably more reasonably priced and I think they are smaller. And I honestly don't think you'd have a problem with them in your tank. I've seen a few tanks in the 90-150g size that were "SPS dominated" and had a pair of bluethroats and seemingly everything was fine, so, ..... I say go for it.
