I have been mysteriously put in possession of a barnacle or two and plenty of flotsam and jetsam for now. But after a few days, when it's all used up, can I feed them green water from my mini-pond?
Can SW barnacles eat FW plankton, aka "green water"?

Assuming plankton is their diet (which im like 99% sure it is filter feeding so plankton fits in there) then yes it would work, for a time, but the FW plankton may not survive well so it may dirty the water quickly, plus it may not be as suitable nutritionaly for the barnacle. So short term should be fine, long term mite be a problem, would eather buy some filter feeder concentrate (silly to use as it is dead so will dirty the water) or buy a cutlure of nanochloropsis, or Isocrisis (my spelling is off on those im sure) as they are easy enough to grow in an airaited 2L pop bottle in the sun.
The barnacles are still looking fine. They eat the green water and I assume they're also eating the drifting hatched copepods.
good to hear, they may eat the pods if they are small enough, the problem with filter feeders is that they tend to have a limited range of sizes that they can consume. but who cares if they are surving. I assume you can see their little feeder tendrels out catching stuff?
Oh, yeah. They rake like crazy. I've even seen their...manhoods...emerging to seek mates. Very crazy. I'll bet if more people knew how easy this was, they'd have barnacles.
Oh, man. I don't know how, but some darn shore crabs seem to have eaten the barnacles. Or the barnacles died and they moved in for the meal. Oh, well. It was cool while it lasted and I'll probably try it again some time.
