| This is a waaaay late reply to this thread. But I thought I'd throw in that we've had no problems keeping Croceas and maximas on barebottome tanks. I do like to place a flat old oyster shell or peice of base rock under them to support them and give them a small lace to attach to.
I do not know the specifics on H. hippopus so I can't be of more specific help on that.
As far as LPS and high flow. They have no problems in a high flow environment, you just don't want a jet of water blasting their tissue away. Our tank with 17x turnover has hammers, frogspawns, brains and scolymias. Just place them in the correct areas of the tank and they will be very happy. Granted our tank isn't a super high flow sps tank, but it is more than the old standard of 10x.
Lobos, and trachyphillas may not enjoy the barebottom condtions too much, I think they may enjoy sitting solidly in the substrate or in the rockwork a bit more. Cyanirina or Scolymia may adapt a bit better to being sat flat on a bare bottom tank. (Just my opinion)
I'm still working on setting my bare bottom tank, and will be sure to try some LPS on the bottom and will let you know how that turns out.
