African Dwarf Frog likes to "ride" the filter
All three of my ADFs like to position themselves under the intake for the wall-mounted filter. They let themselves get sucked up and once attached seem to be very content, even flapping their flippers the way they do when mating. At first I was very concerned that this was happening accidentally and that they couldn't get off. This is definitely NOT the case. They LOVE it. Usually someone is on the filter at all times. Sometimes the larger female will stay on the filter for so long that her skin/back fat (?) will get all sucked up into the shape of a waffle (like the bottom of the filter).
Has anyone else ever seen their frogs do this?
