Was looking for a suitable replacement for my favorite tank "show piece" fish, a Hawaiian Flame wrasse, which I lost due to an overtemp in tank late last year.
(FOTM - Hawaiian Flame Wrasse - Sep '07)
I came up with this beauty after checking out many other possibilities with LFS.
A totally intelligent, high-spirited and active fish. (acts much like a sixline in activity)...Curious and busy, continually snooping and flipping over rock looking for goodies to eat. Hardy and will thrive in wide range of water and light conditions.
"Compatibility" is not an issue as this fish has a strong bearing and demeanor so not bothered by even the most aggressive fish in tank. Could care less about other inhabitants.
Need a very stable rock foundation or the Coris will rearrange tank for you to its liking.
I keep a pile of rubble rock in sand bed in front of tank, which it is content to push around.
Not known to eat larger shrimp or crabs...have never seen do so.
Is carnivorous and will eat about anything. In fact are quite prodigious eaters, so will be quite messy and good filtration is a must.
Will grow up to 6 inches so plan on at least a 75 gallon tank to keep an adult happy.
Fairly deep sand bed recommended, but not required. Mine gets along fine with just inch or two in my tank.
An odd behavior of mine, is that it appears for just couple of hours in AM...is very, very active, then disappears for rest of day.
Am continually overwhelmed by the beauty and coloring of this fish...seems to get more striking as time goes by.
This colorful wrasse is, without a doubt, one of the most gorgeous/vibrant fish you can find at your LFS.

Red to dark reddish head, green iris/pupil, and with a pattern of bright vibrant lateral yellowish/green lines.

Beautiful, bright, exotic blue florescent spots all over body, which transitions in color from red to darkish green from front to rear. Bright red fins, trimmed with bright florescent blue.

Flashy bright yellow tail. Trimmed with red.
A totally cool fish...that does not cost a fortune ($30 for adult at my LFS)
Look for juvenile at LFS as looks much different then adult. Expect many purchasers have not a clue what fish they are really getting. Don't know of any other fish that makes such a dramatic change as it matures. Just saw young one at LFS today for $9.99.

"Shark Reef," Silverdale, Wa)
This is definitely a species to get as a juvenile as you will want to enjoy watching changes as it gets older.
