I had a fourline and it was MEAN to smaller, larger did not matter it was tireless and everyone was fare game. I do not think it is worth the aggravation, but I am overly cautious as ripping apart a tank is not on my top ten favorite things to do :lol:

Another one of my "leave in the ocean" animals. Unless you have done a few months of research, have a tank that is a species only and that is 100% COMPLETLY SEALED you will run into problems. In a reef they will eat everything, they have very low survival rates and in general I would stay away from them.

I love my 4 line, gets along with all my fish great... it's actually my royal gramma that turned into the bully when I added him. The gramma is half the size of the 4line and it beats up on him all the time lol

Problems with the lined wrasses.
1. Although there are exceptions, the six line is a bully. Creating stress and death of smaller species especially newly added ones.
2. They compete with more peaceful additions like mandarins for the same food.
3. They frequently die mostly caused by damage to the fishes mouth as a result of injuries sustained in the plastic bag as they are very active If you choose one look very very carefully at the mouth for damage.
4. In the case of 6 lines they are almost always caught by cyanide. Cyanide is squirted in the rock to stun them and other rock dwellers. The cyanide kills the coral and invertebrates and creatures that also live in the rock. Over 50% of the cyanide caught fish die immediately and another 25% die before they reach the shore. From shore to your tank many are sick and than die but a few survive. The tragedy is that by buying this fish, which is not an attractive fish anyways, we indirectly support the use of cyanide. The four line is a Hawaiian fish and is not caught by cyanide.

Not attractive? I think it's one of the nicest fish I have/ would want to buy

Thanks everyone for your sugestions.
