A few months ago I set up a 25 gallon nano tank with a Sunpod 250 DE HQI light. This will be primarily a SPS
tank. I've added a few small SPS
frags including a blue Tort and a flourescent green Hydnophora. For diversity I added a small one inch frag of zoas and a Torch coral (LPS
) who's polyps expand to about four inches wide in the lower left corner of the tank. I usually research a coral's requirements on Live Aquaria before I buy it, and that's worked pretty good so far. But I'm confused about adequate coral spacing. I've read that the Torch and the Hydnorphora should be spaced adequately away from other corals to prevent them from stinging others with their sweeper tenticles. But what does "adequate spacing" mean? How far apart should they be from the other corals? Two inches, six inches, twelve inches??? I've tried to watch for these sweeper tenticles, including several hours after lights out and have yet to see them. So far, all corals seem to be doing fine, and the SPS
are even showing new growth.
Thanks in advance for any advice!
