The Blue Leg Hermit Crab is a small crab that is an excellent addition to any clean-up-crew. They actively scavenge your live rock eating algae, detritus and leftover meaty foods. Blue legs will occasionally kill a snail if it can't find an adequate size shell when it's time for them to upgrade. Keeping some empty shells in the tank for them to try on helps prevent this.
The Emerald Crab is well respected for its scavenging ability. It will enthusiastically feed on uneaten meaty foods and many types of nuisance algae. Unlike many other animals, Mithraculus sculptus will eat bubble algae and helps clean your aquarium of these algae. Its distinct, flat shiny green body and hairy legs easily identify the Emerald Crab.
The Sally Lightfoot Crab has long been used as a "tank janitor" to help clean the substrate and rocks in saltwater aquariums. As an omnivore, the Sally Lightfoot is the ultimate scavenger, consuming detritus, uneaten food, algae and everything else in its path, with the noted exception of living corals. When this crab gets larger and more aggressive, it will also attack and eat small fish and invertebrates.
The Coral Banded Shrimp will feed on leftover fish food and sinking pellets in the aquarium. They are mostly carnivorous, but they are not predatory. The Coral Banded Shrimp will clean larger parasites and dead scales from your fish at times, and tend to be territorial towards other shrimp that perform the same cleaning function. (Such as the Scarlet Cleaner shrimp). Because of this the Coral Banded Shrimp shouldn't be added to a tank with other ornamental shrimp
Porcelain Anemone Crabs are filter feeders and a great addition to reef tanks and invertebrate tanks. Uses its Feathered "hands" to pull food out of the water column. A group of porcelain crabs feeding at once looks like they are waving fans. Gets along fine with other species of shrimp and inverts. Prefers fine frozen foods. Will sit with anemone for protection, but anemone is not required to keep them.
Flame scallops are fun additions to reef tanks. The scallop shell is 1 inch. They are bright red filter feeders that should be kept in an established, stable tank. They are a moderately challenging tank addition and do not bother other tank inhabitants.
The Shortspine Urchin, or Rock Burrowing Urchin, has an oval to round black body covered with hundreds of uniform, reddish-orange spines. Typically found in the back reef, this night-dwelling algae cleaner is known to burrow small niches in carbonatic rocks (dead corals) to hide.
The Astrea Snail has a unique shell that is pyramid shaped with an olive green coloration. It is best used for cleaning algae covered live rock and eating the nuisance hair algae, as well as cyanobacteria and diatoms. The Astrea Snail prefers a well-established aquarium with ample hiding places and sufficient room to roam. This snail has a tendency of falling over and not being able to right itself back up because of its pyramid shaped shell, so the aquarist should be cautious.
Feather Dusters are filter feeding marine worms with fan-shaped crowns. They make excellent additions to almost any reef tank and require no special care. You will receive a single worm. Please note: Feather Dusters will be shipped either loose, on a piece of rubble, or on a frag plug and may or may not still have their mucus tube intact. The lack of a mucus tube does not harm the worm and they will quickly reform it once placed in you aquarium
Brittle Stars are excellent detrivores and will keep excessive detritus from building up. They like to stay in caves and and other dark places. These animals can be relatively fast, but grow rapidly with regular feedings and become extremely large, so it should be introduced to a large aquarium that is no less than 50 gallons.
The Fancy Arm Banded Serpent Starfish is typically 4-6 inches in diameter & eat detritus. They are able to keep inaccessible areas clean as well as stirring and aerating the sand bed in hard to reach areas. Recommended stocking is 1 per 50 gallons.
