I just added a Fingered Dragonet to my 210 aquarium. I have a refugium in my sump, and there are huge amounts of pods in the tank. I may not even have a problem with the fish, but I've noticed the last two days the fish goes up and down the back of the tank near the overflows. She's not going in the live rock or around the rest of the tank. Just up and down the back for the most part. My question is, should I be concerned? Is there anything I should do to get her eating if she's not? I want to try and nip this if there is a problem before it becomes a big one.
