I recently purchased a blue linkia. It seems to be doing well. It moves around the tank quite a bit, but I have not been able to get it to eat. Most of the time it hangs out around the intake of my protein skimmer. There are tiny feather dusters growing on the glass here and I think that it may be eating them, but the place where he is eating is not where the feather dusters are most abundant. I have tried to place shrimp and a mussel in front of him, but it did not work. I also placed him on a mussel and a piece of shrimp, but once again no dice. I had read that these are two common ways to feed the blue linkia. Any feeding tips would be greatly appreciated.
