I do love my Sixline wrasse. (Pseudocheilinus hexataenia)
Going thru rather vast tank photo collection and just wanted to see these all in one place. (Actually quite hard to get a decent pic of this fish as it very rarely sits still long or slows down enough to catch it. So is very rare occasion that I even get a halfway decent pic of it...
)

I Love My Sixline)
Besides its incredible beauty, it is great fun to watch whizzing around tank, playing in heavy water current and "schooling" around with other fish.
It is a fish with wonderful characteristics.
It will eat flatworms, bristle worms, small nuisance snails (esp. those that prey on clams) and is known to act as a "cleaner" to other fish that might be afflicted with some parasite such as Ick.
I often see it carefully inspecting my larger fish, which will hold still for it to do so.
While it does carry a bad rep for being overly aggressive, mine is the most docile, mellow and fish friendly in the tank. The reason being it was the last fish to be added to the population, other then my flame wrasse, which it does not bother at all. It seems to be that they will not tolerate new fish.
He has lots of personality and fun to watch him following around my coral beauty which his best friend.
The only downside that I have heard of, is that it also loves copepods which will put it in competition with other pod eaters, such as mandarins. But my mandarin is a fat little sausage so does not seem to be a problem in my tank.
So for a cheap, colorful and playful addition to a already established fish population, consider adding a sixline wrasse.
It is the perfect reef fish.
I love mine.
