Try one of the mixed foods like Rod's or LRS fish frenzy since there's different types of prey mixed up in there. See if that gets the fish going.I only tried Nori recently because she didn't eat anything else. Normally I give pellets (about 10 for the tank) in the morning and one pipet of brine shrimp/water mixture at night.
From what you detailed, I probably have been giving too much so I'll I'll actually scale it back. I've been getting some algae growing at the bottom so I'm sure that's a contributing factor.
Thanks for sharing that your fish also has some odd swimming behavior as it wakes up. That reassures me a bit more, but I'm definitely going to go get some of mysis this weekend.
