Why is this fish dam frustrating to feed!? It is the most timid fish I've ever seen!! He's been in the tank for about 2 weeks and is terrified too come out and even think about food. I've tried pellets/blood worms/goby feeders/brine shrimp/mysis shrimp.. and absolutely zero luck.. I don't like letting food just sit in the tank over night. Anyone have any advice too try and feed this dude
