actually though rod, the fuge i want to put them in was originally supposed to be a frag tank, but is more of a fuge now with some xenia and softies in it :- / this tank flows into the original refugium which is also packed with critters before flowing to the sump and pumped to the tank. this is why i figured i could put something cool in the "frag/ fuge" tank that would thrive there and not otherwise survive in the reef tank. just an idea, thought it would be cool to have some seahorses. if i did get some though, i was planning on just getting the little dwarf seahorses and putting a divider in there to keep them away from the powerhead and frags. has anyone had experience with this type of seahorse? they are rather inexpensive when shipped from florida and are said to be quite prolific.
