I posted this before...but anyway, I have brittle star and orange linkia in my tank, both over a year old now. I do spot feed both and use the frozen food by ocean nutritionals-the algae cubes...sorry i don't know exact name Im at work.
Anway, both took to spot feeding very well. I use a long "grabber" that I bought at the LFS. For the brittle, which is usually wedged in the rockwork in his little home he likes, I simply grab a little of the chunk of partially thawed cube and also sandwich in a little flake, and i drop it right next to one of his arms..sure enough, he grabs it pretty quick and brings it into his crevice. He has a spot right near a powerhead, so I have to turn that off for a minute.
For the orange linkia, he is a bit more tricky, and the timing has to be right...he has to be in a good position which I am usually lucky to find him most of the time in. With him, i do the same as above, except the chunk of algae is thawed out and again some flake is in th egrabber too. I use the flow of the water in this case, and i simply get the grabber right next to his middle, and kinda let the food "dissolve" away from the grabber. Sure enough, he lifts an arm or two and kinda "catches" the bits. Then depending if he is on the glas or rocks-if he is on the glass i stand there like a moron for a few minutes and try and give him as much as i can in the flow...if he is on the rocks, i drop the rest in a crevice right as close to it as possible for him to move and grab, which he does occasionally.
I think they learn after a while if thats possible on how they are getting fed. But both are happy, healthy and are very active in my tank.
Hope this helps anyone wanting to keep them. I had an orange way back when my tank was new and it died within a couple of weeks...tank was too new i guess, and as usual it seems was under the assumption it would simply find its own food all the time, or my acclimation wasn't long enough or something.
