Clean Up Crews

The Dwarf Red Tip Hermit Crab is a highly active and efficient scavenger, making it an excellent addition to any marine or reef aquarium cleanup crew. Closely related to the Blue Leg Hermit Crab, this small omnivore constantly explores live rock and sand beds, reaching tight spaces to consume algae, detritus, and leftover food. Also known as the Red Tip Hermit Crab, this species is easily recognized by its bright red legs and face. It belongs to a group often called “equal-handed hermit crabs,” as both claws are similar in size and function. Native to the coastal waters of Mexico, this hardy invertebrate thrives in well-established reef or fish-only systems with sandy substrates, where it actively forages and helps maintain a clean and balanced environment. Benefits in the Aquarium: Excellent algae and detritus cleaner Helps aerate and stir the sand bed Supports beneficial bacterial growth Reaches tight spaces other cleanup crew cannot Habitat & Care: The Red Tip Hermit Crab lives in empty snail shells of various sizes, so it is important to provide extra empty shells to support its growth and natural behavior. It should be kept in a mature aquarium with stable conditions and plenty of live rock and algae for grazing. If natural food sources are limited, dried seaweed or algae-based foods can be offered as a supplement. Important Care Notes: Acclimate slowly to avoid pH shock Keep only in copper-free systems Avoid predatory tank mates Ensure a stable, reef-safe environment

The Sand Sifting Sea Star, at first glance, seems to be drably colored like most bottom dwellers. But closer inspection reveals a striking beauty and serenity to the alternating bands of brown and beige that dress this invertebrate's thick, spine-covered arms. Like other starfish, Astropecten polycanthus efficiently consumes mass amounts of detritus and uneaten foods. This nocturnally active member of the Astropectinidae family can move large amounts of sand as it burrows into the substrate in its search for food. This peaceful omnivore will effectively clean even the largest home aquarium of detritus and left over food. Like other starfish, the Sand Sifting Sea Star will also consume small invertebrates, including shrimp, urchins, mollusks, bivalves, or other small sea stars. As such, the Sand Sifting Sea Star should be actively fed a varied diet consisting of natural food sources, especially in well-established marine aquariums. Otherwise, this voracious feeder will quickly clean your aquarium of detritus and then burrow into your substrate, starve, and eventually begin to decay. To foster its feeding habits, the Sand Sifting Sea Star should be kept in aquariums with large, deep sand bottoms of several inches in depth. Since it is slower moving than most fish, the Sand Sifting Sea Star should not be housed with natural predators, including Puffers. Like other invertebrates, the Sand Sifting Sea Star is very intolerant of sudden changes in oxygen levels, salinity, and pH and cannot tolerate copper-based medications. To successfully acclimate new specimens to your aquarium, use the drip acclimation method and never expose the Sand Sifting Sea Star to air while handling. Breeding in the home aquarium is extremely difficult with no distinguishing characteristics to help differentiate between males and females.

The tiny Bumble Bee Snail benefits most marine reef aquariums in big ways. Heralded for their small size and beautiful coloration, Pusiostoma mendicaria can get into small crevices and tight locations between rockwork. Here, they clean away detritus, including uneaten meaty foods and decomposing organisms. This tiny member of the Buccinidae family also burrows into your sand bed, consumes sand-dwelling worms, and helps aerate your substrate. Plus, with its striking black shell, striped in elegant white to yellow bands, the Bumble Bee Snail is indeed beautiful to observe. For best care, offer ample hiding places with large areas to roam. The Bumble Bee Snail prefers to consume foods off of live rock and deep sand beds where it can forage for food undisturbed. Like other invertebrates, the Bumble Bee Snail is sensitive to copper-based medications, high nitrate levels, and even the slightest fluctuation in water parameters. Though peaceful, keep in mind that the Bumble Bee Snail is a carnivore. If there is insufficient food, the Bumble Bee Snail may feed on other snails in your aquarium or indiscriminately consume polychaetes whether beneficial or the more troublesome bristleworm. In well-established systems, most Bumble Bee Snails do not require supplemental feeding. However, if sufficient food sources are unavailable, supplement their diet with offerings of meaty foods, including finely chopped brine or mysis shrimp and frozen meaty foods. The Bumble Bee Snail is extremely difficult to breed in the aquarium, partly because there are no distinguishing characteristics between Bumble Bee Snail sexes.

The Spiny Star Astraea Snail has a unique shell and a ravenous appetite for algae. Unlike many bottom dwellers that are dressed in drab colors to better camouflage themselves against the sand bottoms, Astraea phoebia boasts a pyramid-shape shell with beautiful, green, yellow, and tan coloration. The Spiny Star Astraea boasts pronounced projections on their shells creating a sculptured spiral star shape that is sure to dazzle the eye. Though interesting to observe in your home aquarium, the Spiny Star Astraea Snail serves a greater function of cleaning algae-covered live rock. It is very adept at keeping your aquarium clean. In fact, this small herbivore prefers to feed on nuisance hair algae, as well as cyanobacteria and diatoms. Some aquarists also report that the Spiny Star Astraea Snail actually consumes the entire hair algae structure, which helps prevent immediate further algae growth. The Spiny Star Astraea prefers established aquariums with ample hiding places and sufficient room to roam. In addition to eating algae off of your live rock, this member of the Astraeinae family will also clean your aquarium glass. However, the Spiny Star Astraea Snail is not known to be a climber like other smaller-shelled snail species. Care needs to be taken to observe the daily activities of this hungry snail since it has difficulty righting itself if it falls or is knocked upside down. Like other invertebrates, the Spiny Star Astraea Snail is sensitive to high nitrate levels and will not tolerate copper-based medications. The Spiny Star Astraea Snail requires a gradual acclimation period, preferably the drip acclimation method (often over two hours), since it cannot tolerate even minute changes in water parameters. If sufficient food levels are not present, supplement the diet with blanched spinach or lettuce and vegetable-based tablet foods.
