Thanks Matt. I've only ever had Ancistrus and Cactus plecs before and they have always eaten when the food has gone in but my Arabesque doesn't move. She's temporarily in a tank with Guppies who I've seen eating the waffers and pellets etc.
I'm probably getting too worried over nothing but as she ...

Hey, I'm getting worried about my Queen Arabesque. I'm pretty sure she's not eating. In the last month I moved her into a new tank with sand, caves at both ends and floating plants. She's the only bottom feeder. All water levels are good, temp is 26C.
I've tried waffers with high spirulina content ...
