Fish suggestion

Harvey,

I have a 37g too, 24"l x 24"h x 18"w. Have a pair of ocellaris in it. Am thinking of other fish to add to this tank as well. If anything, may consider a 6 line wrasse (which you already have) or a royal gramma. The problem with a 37g is that few active fish will fit into such a small tank, plus I don't want to overstock.

As for the longnose hawkfish, they grow to 5" and can be aggressive toward other fish:

We had a spotted hawk in our 42g hex. It grew to max size (3") in no time. While it was an interesting fish, it went back to the lfs because it was too aggressive for such a small tank. Man, it would stare us down from its perch on corals and rock

I bet a 5" longnose could eat just about any invert in one's tank. Other than the size I would definitely recommend going for one, I've always been fond of them.

I've always found chromis and cardinals to be rather dull.

The Longnose Hawkfish adults can grow to the MAX of 10.0 cm (4 inches) thats length from nose to end of tail, so really a small fish.

These fish are very peaceful and not aggressive. They will not bother corals in a reef, but being that they are carnivores, I could see it eating smaller ornamental shrimp and smaller hermit crabs though. My shrimps are bigger then him so the longnose stays away.

I've had the Blue/Green chromis before and I do think they are nice fish. Its just that I've already had them before and want to try something slightly different. Hmmm, the Blue Reef Chromis (http://www.fishbase.org/Summary/Spec...iesname=cyanea) has caught my eye though...

Just because I'm pragmatic, I'll point out that Fishbase lists the longnose at 13cm... however I don't know if they would reach that length in captivity (when was the last time you saw a wild-size tang in someone's aquarium).

I had a longnose hawkfish for quite a while (lost it due to jumping). Never aggressive, always visible, lots of personality. Maxed out at 3.5 inches. Really don't see how it could eat even a small hermit. The only reason I haven't replaced it is because I got my old one at such a good deal ($24) and said I wouldn't top that for another. One of my favorite fish of all time. Can't wait for the right deal to come up.

You might think of a Flame Hawk. It is a very colorful fish, and is quite small. The problem is getting one that is inexpensive. Like any hawkfish you need to be careful if you have small shrimp.
