I recently started hatching baby brine shrimp in hopes of feeding them to my mandarin, who had eaten all the pods in the tank. After squirting some in the tank today, I started wondering if my SPS corals would eat them. For those who don't know, baby brine shrimp are very small... on the verge of being microscopic and just a little bigger than a rotifer. I tried to target feed some of my corals that have branches close to the front glass so I could see if the polyps ate the shrimp.
This was daytime feeding. Nightime may have worked better.
Staghorn acropora (probably nobilis). aggressive eating. Every baby that touched a polyp was eaten.
Bushy, thinner branched acropora (species unknown) About 3/4 of of babies that touched polyps were eaten.
Pocillopoa damicornus: about 1/2 of babies that touched polyps were eaten. Didn't seem to enjoy them as much as the staghorn.
2 different colonies of montipora digiata: won't eat any even when I forcefully squirted them into the polyps.
Conclusion: Hand feeding your SPS would be a lot of work if you did it every day. If you have a prized coral it might accelerate growth and it's fun to see them eat.
