I've been a lurker here for a long time and I have read through this whole thread a number of times and I finally decided to get off my butt and join the forum.
My experience with Leopards began in January when I was at the LFS and the manager who has since moved (

) saw my partner and I and said, "There is a wrasse here you need to buy." So he showed us this around 3 inch long female bipartitus which he told us was one he had special ordered for a guy a year back as a tiny little baby and this fish had been returned for some odd reason. Anyway, we picked her up thinking she could go into our 55. Then I started with some research after the fact ( I know this is horrible but the ending is positive) and realized she wouldn't be a good fit for that tank due to a large amount of crushed coral in the tank. She ended up in a 20 long in quarantine for a while. I know this isn't the best, but we set up our DeepBlue 90 RR back in the early spring with her in mind (oolite sand this time). She's a total pig, she will eat anything we put in the tank, large pellets, small pellets, PE mysis, LRS Reef frenzy, Lifeline, whatever, she's not picky. So this is one success story.
Fast forward a few more months and I've caught the bug that is wrasses and Leopards are totally awesome fish. Another LFS had a small negrosensis in and it was eating frozen, so it came home. It was a pain though, was always on a different schedule and I would feed when I saw her out. Made it all the way to the one month mark and I got a text at work from my other half, to call because there was bad news. While doing a water change, the little one freaked out and bashed into the glass, not once but twice. big sigh Still need another black leopard.
Around 3 weeks back, we were at the LFS to pick up some things which were NOT fish, or so I thought. They had a gorgeous ornatus which was out and eating. So she had to come home. She went directly into the Display tank. She hid for a few days, and came out a bit here and there. She is out more and more now, and picks at the rocks when she's out. So far, so good. She's not eating pellets yet with the other wrasses in the tank, but she will eat PE mysis.
Anyway, these are my experiences with Macropharyngodon so far and I can't wait to post some pics, when I can get them. Wrasses aren't the easiest to get to sit still for photos.
