hi, i've got a quite unusual problem, one of my axolotls' refuse to eat worms. i've always used a pair of tweezers when i feed them so they seem to recognise them as something shiny that brings food. anyway, at first he ate worms but nowadays he just swim to the surface and tries to bite the tweezer instead of the wriggling worm. at first i thought that he suffered from some mental instability (a salamander that refuses worms?) but he seemed to be able to eat frozen bloodworms so i stopped bothering. so my question is; does anyone know the reason of this weird behaviour?
