Maybe it's just my ADFs but I have to question the repeated knocking of their eyesight. I can drop food in the other side of a 20 gallon long tank, and they find it within minutes. maybe their sense of sight is bad, but then their sense of smell must be phenominal. They like to hang out together (I have 6 of them) in a cave, but all come pouring out when I feed them, again, on the other side of the tank. I feed mine every second or third day, and this is fine. Live foods will be great, and frozen is good too. I don't see how live foods would be a problem. Frogs in the wild don't get food (live, frozen or other) dropped right in front of them, they have to hunt for it or they die, just like every other animal. I used to feed mine in a little baby food container, turned sideways, because I believed they would starve otherwise. After a couple feedings I found they ate the fish food that floated around the tank and ignored their food. And the fish pulled the frog's food out of the container. I stopped using the container months ago, and I have never fed them with a baster or anything. I feed my frogs live blackworms every couple of weeks, and they love hunting these little guys. ADFs are grat fun to watch, and don't require a lot of effort.
