torch coral feeding?

[chris88]

Okay, so I have been trying to feed torch corals for the past 2 years in 3 different system and I have yet to see any of them (4 different) show any signs of taking the food into their mouths. I have feed the rainbow and beyond and the best I get is when they grab the food and secret some kind of slime and then it either falls of or eventually, when I turn he flow back on, get blown away. Now, in regards to candy canes and most other LPS's, I could feed them dryer lint and they will take it in.

any suggest or luck with feeding torches?
