The next photo shows one of the male (has a pointed anal fin, gonopodium) T. perugiae swimming in search for food. As soon Blood-worms or Black Mosquito larvae are offered, they go crazy. Notice how the barbels are pointed upwards. This fish sure is a surface feeder, but will get even to the food that falls down. The second photo was taken just before this dwarf catfish ate the offered Bloodworm. Very quiet during the day time, but they will go out as soon frozen food enters the water. In the night time they swim close to the surface, they remind me of Bats.
