I've given my GoPro to the freshwater gobies. Their reaction surprised us all. They are way smarter than We think. They would make great videographers. The fish in this tank are: monkey goby (Neogobius fluviatilis), 2 toad gobies (Mesogobius batrachocephalus), 2 spined weather loaches (Cobitis taenia), 5 Amur bitterling (Rhodeus sericeus), fancy guppies, and one very blue Australian red claw crayfish (Cherax quadricarinatus). It started out as a Dniester Biotope tank, but lots of other animas found their way into it.
