Coral food?

[Navarchus]

I used to use a turkey baster or Kent marine squirt with a small modification!
I took a soft drink 2 litter plastic bottle; cut it half the middle and then I inserted the squirt/turkey baster into the bottle neck.
Now in order to feed the coral you load the squirt/turkey baster with mysis and cover the coral with the half bottle, sort of dome shape. Then discharge the food.
