Have you tested your water? I have an orange one and a green one. My orange wasn't in too good of shape when I got it, but within 2 days it was ready to eat. If it were me, I would test the water, if the water is good, then I would try and target feed it. The easiest way to get the tenacles to come out is to use a turkey baster. I usually use frozen mysis,brine shrimp,plankton,squid, or whatever I have on hand at the time. Mine like bigger pieces. When you thaw out the food in tank water, I will suck up a little of the juice and squirt it on the disc, then wait a little bit for the tenacles to come out, then sqirt the food on them gently so the tenacles can catch the food. Make sure your fish, and shrimps don't try and rob the disc's food. Disc's are kinda slow eaters so I generally babysit them until the food is gone. I aslo generally just go ahead and feed the other fish at the same time so everyone is happy and the disc is less likely to be robbed. HTH, good luck.
