well id say try it in both. from what i understand they can be fond in both very shallow water and very deep water. leps have larger polyps then favia's in general, i would think it came from deeper water with less of a turbid current and good but not bright lighting. i would start it out mid way 9 moderate lighting and flow and see how itdoes from there. ive never had a problem if i moved a coral from bottom to top, but if i had to move it from top to bottom, it, was because of a problem lol
