Lampeyes and ants was (Re: Diapterons)

I remember when I lived in Seattle, I knew the keeper of the Tropical house at the Woodland Park Zoo, Frank Slavens, and he was having good success feeding what he called "Moisture Ants" to the Dendrobates auratus that the Zoo was breeding at the time. He took a plastic plate with raw hamburger that had been left out (the ants had already colonized the building) for a few hours and was literally swarming with ants, and placed it in the frog enclosure. Man, frogs boiled out of nowhere to snap up those ants! If I understand correctly, certain fish spp. will feed on these and other types of terrestrial food items during the right time of year (which may be all year in the tropics) and they form a large portion of the fishes diet then. I have ants in my house already. They are small (about 1mm), black and plentiful. I would not suggest introducing them into your house simply to feed your fish, but rather exploit this wonderful live food if they present themselves. Here in the temperate zone this availability will be seasonal of course, yet still a great source of free protein (and Formic acid probably).

Anyone know of any benefit to fish from eating foods rich in Formic acid?? Enhanced color, perhaps? I wonder if Lampeyes feed on ants and if this would be a way to get them to color up again after capture in the wild? Hmmmm. I'll have to experiment with this....
