This fish is primarily nocturnal, so it is advised that you feed them at night. Elusive, secretive, and beautifully banded in orange and black, the kuhli loach looks like a Halloween swizzle stick, complete with barbels that help it to locate food on the bottom of the tank. The kuhli loach ( Acanthophthalmus kuhlii) has got to be my favorite freshwater aquarium fish. So, in no particular order, I present these fish. They all have certain requirements but if these requirements are met, you can have some nice fish to accent the fish that reside at mid level as well as any that stay at the top level of the tank. Here are 5 great bottom-dwelling fish for the freshwater fish aquarium. It all depends on the species of the fish. Herbivorous fish such as the otocinclus and the plecostomus also benefit from leafy greens. Usually a sinking pellet or tablet will suffice. Now that is not to say that you can get away with not target feeding bottom dwellers because you can’t, as these fish often have certain food requirements that aren’t remedied by the occasional morsel that makes its way to the gravel.


Fish that spend the great majority of their time on the substrate often do a service of sorts by picking off any food that is missed by the fish that inhabit the upper echelons of your tank. Fish that stay primarily on the bottom of your tank are known as bottom dwellers, even though they often move about through all strata of the tank.
