yes, i also target feed my brittle star 2-3 times per week with a chunk of prawn, squid, or whatever i feel like feeding him. keep in mind that they are great scavengers and whatever food doesnt get eaten by the fish the star will most likely find. last year when i went on vaca the girl i had taking care of my tanks didnt feed my star fish for 2 weeks and when i came back he looked perfectly healthy and normal.
