Hi all,
Luis that is great, it always amazes me that small fish will take on a big worm. I had 2 Apistogramma fry grab a worm (intended for an adult), and they had a tug of war for several minutes before they managed to get an end off each. The portion they had was almost as big as them, but one not only managed to eat the bit it had removed, but went back to another go at the middle section.
cheers Darrel
