Re:Surprise Dragonface Pipefish fry!

Unfortunately, a still container will eventually scum over such that there will be no gas exchange and everything will suffocate. But it sounds like they might do best in a kreisel setup where all the flow is from water. Or, what about a divided culture with fry in one side and air bubblers on the other, separated by mesh the fry can't get through? Then you could really pump the air into the screened side, which would cause some water movement on the other while still protecting the fry from the air. You wouldn't get a lot of movement, but you don't want much either. I certainly like the Apocyclops, but I also certainly wish N1 were about 20 microns smaller with N2 about where N1 is now. But if wishes were fishes then they'd all be captive-bred by now. I can't help but wonder if there's something soft-bodied out there that we need to find, like Karen's ciliate, that can serve as a bridge to copepods. Copepods are awfully hard and spiny and must be hard to eat when the relative size difference between predator and prey is low.
