I have no personal experience but I've heard they can get aggressive as they get larger. From what I've seen, $70 is a good price for one.
It's been in a 155g tank for a while now. I'd be putting it into my 75g. The comments above make me concerned that it will eat my hermits and shrimpers! Maybe this is the reason when I asked if he had any hermits for sale he said he couldn't find anymore! Sounds like I should not get it. Which wrasses do not eat hermits and shrimp?
fairy and flasher wrasses, pygmy wrasses among others.
Do they hide in the sand? I bought him he is in the tank. It's night time I can't find him.
