Some freshwater aquarium species have a unique trait, that is highly beneficial for an aquarium – sand sifting. It is an interesting behavior when species literally move sand around, sounds pretty simple, right? Well, it is more beneficial than you think. This article will break down, what sand sifting means for an aquarium, and I will also introduce to you 10 amazing sand sifting species.

Why Are Sand Sifters Beneficial For an Aquarium?
Before getting into the sand-sifting species list, let me tell you why they are beneficial to your tank. Sand sifters often move sand around, by searching for food, or by just being themselves. For example, Corydora species often dig around the sand looking for food, which sinks to the bottom, while species like Malaysian Trumpet Snails naturally hide in sand, also moving it in the process.
Sand sifters are beneficial to an aquarium because some of them eat all of the leftover food on the bottom, which would just rot if not eaten, while some species also help remove trapped air bubbles in the sand, that can become toxic after some time. These are the reasons, why you should really consider adding a sand sifter to your aquarium.
One thing you should know, is that sand sifters are not as effective in substrates like gravel, pebbles, or any other heavier substrates. Light and easily movable types of substrates like sand or soil are ideal for sand-sifting species.

The first sand sifter on this list is the famous Bristlenose Pleco. It is a bottom-dweller fish, that sifts through the sand, looking for food. They are often kept in community aquariums, sometimes in larger groups.

Even though they are not one of the biggest plecos available in the hobby, they still reach a significant size (4 – 5 inches).

Frequently Asked Questions
Can You Keep Sand Sifters With Gravel Substrate?
Sand sifting species are best at cleaning lighter aquarium substrates, like sand or soil. Gravel can be heavy, and for some sand sifters, it would be harder to find food between gravel pieces. They would still be beneficial to the tank, but not as effective at cleaning if there was sand as a substrate.
Is Sand OK in Freshwater Tank?
Sand is probably one of the best substrates you can choose for a freshwater aquarium. It is less likely to damage your fish by being sharp, and for some species, it is well-suited if they want to burrow or sift through sand.
Writer's Thoughts
Personally, I love sand sifters. They help clean the tank, and in general, are highly beneficial. There is a good choice of species, ranging from large ones like Clown Loaches to tiny creatures like Malaysian Trumpet Snails. I hope this article encouraged you enough to get some sand sifters in your tank.
