I recently got one of these guys. He loves to eat frozen mysis shrimp. I also feed my other fish frozen brine, formula one, and some pellets. The pearlscale doesn't seem to like any of it although I do feed fresh scallop meat from the grocery store once and a while and he picks at that a little bit.
They are very fun fish to watch. He does a weird shaking, vibrating thing when he goes near my peppermint shrimp? Anyone know what that is? Seems like he wants the shrimp to pick at him. Has anyone seen that before?
