I recently bought a Top Fin Aqua Scene Desktop Aquarium (1 Gallon) from Petsmart. After getting it ready and placing my male betta in, I turned on the filter and he began swimming up and down on one of the sides quite erratically as if he was trying to get out. The filter is an undergravel filter.
Once I turned the filter off, he began to calm down and explore. When I turned it on again, he started to swim up and down like before. Is it possible to keep the filter off or would it dirty the water? Or should I keep the filter on and let him get used to it?
