Mixing wrasses

The SD will probably be fine unless the sixline is a real beast. The SD will get bigger than the 6 line though.

Seriously guys, you have not heard of the SD wrasse? I will say it's not a fish generally caught for marine tank trade.

 

yeah, big ones are a pain in the neck! i only tried to keep a big one in my reef once... it ate my arrow crab..i got mad

luckily enough, the small one can't do any harm until it gets bigger, which will be in quite a while..

 

I didn't know it was a reef tank these were going into.

The Sd might cause issues even before it gets big. It's a good thing you didn't get a blue head wrasse as those, and all Thalassoma wrasses ( lunar, girdled etc..) will eat anything they can fit in their mouths. So, they will eat smaller fish, and also your CUC.

 

oh, i looked up their care and some sites said reef safe and others said with caution.
