Before today I had no clue polyps could swim. I accidentally jostled a loose polyps and it freaked out and started pulsing around the tank then stuck itself to the tank wall. I was pretty impressed and I managed to get a fuzzy video clip of it swimming and then landing. I might post that up here soon.
So anyways, I will probably culture some polyps in culture dishes or set up a small 1.5 gallon tank for them to grow in. I don't think I will get the polyps in the separate tank to produce ephyra. thats just too unpredictable. I will likely work with cultures for that matter.
