The Tomini Tang is in the genus Ctenochaetus (pronounced ten-oh-key-tus) and is one of the more commonly kept tangs due to it's staying small as an adult. Tomini Tangs reach up to about 6 inches in size and are fairly hardy too. They have a brown body with brown and yellow dorsal and pelvic fins with a white caudal fin.
They are considered excellent scavengers that are reef tank friendly. The Tomini Tang will constantly pick at the live rock and glass looking for algae and other tid bits. They even go after and eat fish poo with gusto (gross - I know right). They are the prototypical janitors in your tank.
These Tomini Tangs can be kept with other unrelated tangs provided you have a large enough tank. They are generally peaceful but can be a bully to species that are introduced after them. But the bullying should wear off with time and they should coexist with most other species just fine. Obviously there are always exceptions to this.
For food, the will be constantly picking at the rock work and glass but try to give them a good diet, heavy on the greens. They do eat dried algae (called nori) although perhaps not as aggressively as some other tang species. Flakes, pellets and frozen foods are good to mix in too.

Tank Mates : Generally peaceful but may be quite the jerk to new arrivals. It's not advisable to keep them with other tangs unless you have a much larger tank. We have kept them in tanks (120 gallon plus) with other tangs (non related tang species) and they were fine.

Tomini Tang Comments and Tips
|From: Tomini Tom|
My Tomini goes after every thing I put in my reef tank. It does an excellent job at keeping the rocks clean and is really friendly with all of my other fish and leaves the inverts and corals alone. This is an excellent fish.
More Tang & Surgeonfish Profiles
This is another tang that is considered very difficult to keep because it doesn't adapt very well to aquarium life. Hard to get on foods and is known as an "ich magnet". Definitely keep this tang with a cleaner shrimp species.
The Black Tang is an extremely rare tang that goes for ridiculous prices, anywhere from $600 to $1,500 or higher depending on the size. Considered just as hardy as the other Zebrasoma tangs.
Another tang that needs lots of swimming room. They are always on the move and look fantastic. Try not to buy the very small ones though, they don't seem to adapt to the aquarium as well as those 2 inches plus in size.
