I don't know anything about the seahorses, but the Queen Conch will eventually get big (8-10"). I have a small (1-1/4") one in my 55g, along with a similar size Fighting Conch. The Fighting Conch has grown about 1/2" in a month. The Queen is new. My thoughts are that they will be good for the DSB until they get too large. At that point, either a larger tank, or I take it in for credit at the LFS.
