I've had my trio of bicolors (first darts ever) from Quality Exotics for about a month and a half now. Two of the frogs are voracious feeders, and have exhibited normal growth, but the third, who has always been the runt, has had trouble striking at flies, and does not move normally like the others. It can only catch food items when they are directly below it's mouth, and it often makes several strikes in vain before catching anything. Needless to say, it has been growing thinner by the day. I'll be moving it's two tankmates to a 10 gal today, hopefully giving him a little better chance of getting food. Anymore suggestions? Has anyone else experienced this in their froglets?
