Mixing wrasses

[Snappy]

I personally believe the tank size has a lot to do with them fighting and jumping. They need room to flee if threatened and the best option is for them to have space to swim out of harms way horizontally and not vertically because they often can't stop when they reach the surface. I have 9 wrasses in my tank and they all get along fine but they have also ample room. These include a yellow coris, radiant, mystery, leopard, pencil, solar, 6 line, etc.
Some like the 6 line for example don't play nice with others that have the same body shape so try to mix them up a bit.
