My sand in my tank is "sugar size", ie, Size 0 aragonite. I will edit with a picture of the bag. I have a couple unused bags laying around.
Yup.. they do. I am an oddball with the Mystery wrasse, I really don't find it appealing at all, but soo many others love that wrasse. If I were to get any wrasse that isn't a leopard it would be a
Hawaiian Flame Wrasse. They go for $150 at all the LFS around me when they get them, but they are usually a special order thing because most LFS don't want to have that expensive of a fish just sitting in their tanks without a buyer already lined up unless it is a LFS display tank. Problem I see though is it says 75G is minimum for that one, I didn't know that one, they are small so I thought your 34G may work, but looks like it won't.
Oh ya, Mystery wrasse is in the Labridae family, same as my yellow wrasse, and are known to jump. My yellow wrasse tries to jump out about once a month, but my closed canopy prevent it from carpet surfing. I still get a water streak down the front of my tank to show me that it tried to get out. They are not as bad of jumpers as flasher wrasses, but still, they will jump. I have never seen my leopards attempt to jump at all.
