Flounders

Anyone have flounders?

Long time ago I got a 3" one, and it could hide in the sand and shoot out and catch a fish on the other side of the tank so fast you only saw a cloud of sand. Do did not work out too well.

What genus was the flounder? I only have an experience with my new dwarf sole (Aseraggodes sp.) that's barely 2 inches long. I just see it chilling on the bottom after lights out, searching for some mysis I drop in every night. It's been very peaceful, living with my clingfish.

Good question. Was darker than yours though.

I've kept a few species of flatfish, but not in a reef system. Tonguefish, lined sole, and hogchokers are the smaller ones I've kept. They're all pretty easy. Lined soles will stick themselves to the side of the tank as often as the substrate IME.

I also kept Winter flounder and Gulf flounder. Of all the species I mentioned, the gulf flounder would be the predator I'd watch out for. Any member of Paralichthyidae (large-tooth flounders, including Summer and Southern) will be a very effective predator.

Eventually my Gulf flounder got so tame that they'd feed at the surface, and they would splash tour groups when no feed was offered! Really cool animals. Flatfishes are the most-asymmetrical vertebrates.
