Was doing maintenance on my seahorse tank which has a very shallow sandbed (so some spots are even bare) and saw this lying on the bottom. Figured it was a stem or piece of dead plant/macroalgae and pulled it out but the more I looked at it, the more I wondered.... was this a living creature other than a plant? I can't stop looking at it and the more I do I don't think it was a plant. I guess my concern is, if it's bad, there's probably more and I should do something. Ponies and coral are all OK, so far.
