I've decided not to wean my new angler to frozen food. This is my 1st warty, my last painted angler lived for 2 years on live food. I still haven't found anyone that has kept them longer than that, and around here even though they have become quite popular, for some reason people don't seem to keep them for more than a few months. But this is why I decided not to wean mine, 1st off once they are wean they basically become a fish ornament. I never saw my friend's weaned angler ever move, he was in the same spot every time I went over to his house. He mysteriously died at about 4 months. My anglers eating live food cruises around the tank constantly, still keeping their predator instinct. My new one and my last one takes an evening swim that is very entertaining, using his feet to bounce off the glass and rocks. It's also fascinating to watch the hunt. the enticement with his lure, the hypnotizing with his lure, the slow creep to get into the perfect position. A weaned angler will find a spot and just wait for you to drop food in his mouth, and I have not seen any proof that the nutritional value of feeding frozen lengthens in any way their lifespan in captivity. The same psychological finding that people report about predators at the zoo also apply to the predators in our tanks.
