eating the carcass doesn't mean he killed them... all fish are opportunistic so if there is a free meal (ie dead fish) they will pick at it. Melanurus are usually pretty mellow... but all fish are different... most of the "rules" are generalized to makes things easier, but they are never 100% accurate... keep an eye on him... i feel its unlikely he killed a jawfish or a blenny as they dont really compete for the same food or hang out in the same area of the tank...

he could have bumped his head on a rock while diving in.. if so, it will heal in time. if not it could be fungal... which means you'll have to take him out and QT and treat. judging by the pic it looks like a scrape... but i'd have to see a better pic.

interested in the skimmer if you part it out!

that is pretty cool for sure!

I think red sea is big now because its all inclusive (for the most part). Tank, stand, sump, plumbing etc is pretty good for the price (and lights if you go that route). My only issue is the stands. I have a 425xl... not a big fan of the stands... but they are nicer than many other products available.

halichoeres should have sand, they bury nightly to sleep, and since sand burying wrasse dont create a thick mucus coating like flashers or fairies, they should have sand to retreat in and feel comfortable. Also, they will more than likely bust up the lips trying to bury which will make them stop eating, and eventually die... leopards are far worse at doing this, but a small sand bin works, if they can find it easily.

freshwater dips are "OK" for flukes, but does absolutely nothing for ich or velvet. Hypo is best, or tank transfer, but a QT tank with cupramine is always handy to have as well.

fiji pink is light and blows like crazy... you'll notice spots quickly that are to much flow directly on the sand. you can always put a rock on top of that spot as well to divert the flow.
