I have a 140g with eurobracing and our Clown Fairy Wrasse jumped onto the hardwood floor. (height approx 6 feet+)....he lived..but those are lucky jumps. I now have a larger light that covers pretty much all the area of the eurobracing except a small area where my autofeeder is. You can cover the top with black egg crate material.....just don't get it too close to the hot lights! LOL
If you are getting a wrasse check out the one we have.....he is really cool...but I swear there are hundreds of varieties.....Just watch some eat shrimp and snails!!.. Also don't always believe your LFS.....do some research on Canreef and/or the internet. You will learn who to trust over time.
have fun!
