I have a 5 gallon tank with two fiddler crabs and an African Cichlid. The two crabs have a plant they climb to get to the surface for air, and I have a tetra whisper internal filter rated for 2-10 gallons. The filter doesn't seem to be providing enough agitation on the water's surface to aerate the water enough, so the Cichlid hangs out at the surface like he's gasping for air. How can I aerate the water more? Would an air pump help?
