I am looking for something that is going to burrow into my sand and help turn it, but is not going to take over my tank like snails do. Any suggestions?
Sorry forgot, its a 75 gallon freshwater with pool filter sand as the substrate.
They are native to coastal waters the Indian and Pacific Oceans. They are very small fishes: with the exception of the larger Donaldson's sandburrower, Limnichthys donaldsoni, most species reach only 3 to 7 cm in length. They live in shallow waters close to the shore, burrowing into sandy areas swept by currents or by surf.
