I STARTED feeding useing a eye dropper that came with one of my test kits, feeding twice a day by the eye dropper with blood worms. once he knew what was going on he would wait for the times I was feeding and be right there. Always making to sure to feed him in the same spot everytime where there is low current. I then decided to try a algae clip with a frozen chunk of blood worms. It worked great. By time it would start thawing he was already there eating away. He is now starting to get fat and healthy again. Ive tried this method with both of my mandarins a pyschodelic and a spotted worked great with both. No more buying expensive live feed off the interent. Hope this helps some people. Also found out they will eat Prime reef flakes also but couldnt think of a way to feed accuratlely.
