Hey Jared!
It's Jason from Greenwich Aquaria... You working in LI still? I'm looking for people and thought I'd check on you first! jason@greewnichaquaria.com...Hope you're well!
Unlikely they were going after much else at that depth. Only a few fish are collected from The Cooks Islands, Ventralis anthias (the true one, not the one out of Tonga), Galba damsels, Olivaceous anthias...
The only other Cook fish I've seen lately is the Galba.
Getting back to LA...you don't...

1) Black clown
Not uncommon to lose these, brook can run through in less than 24 hrs
2) Hectors goby
Tricky little fish, my guess the CB
3) Fang blenny
All of the fang blennies have a very dubious record in captivity.
IMO, nothing to do with your tank, just not picking appropriate fish for your...
