Yeah, but some people like to post threads here regarding sponges, tunicates, fire corals, etc. because many of these species rely on feeding instead of deriving energy from light, just like non-photosynthetic corals. Most of the people who have setup tanks to care for non-photo corals post in this forum, and not in the generic "Invertebrates" forum. They are the ones that people are seeking advice from, so I think we can forgive them this.
Seriously, did you actually think you were adding to the discussion?
