    Halloween Hermit Crab

    10 in stock

    The Halloween Hermit Crab is a standout member of your aquarium cleanup crew, thanks to its striking orange and red banding. This crab's attractive color variation adds a beautiful accent to any marine aquarium. Beyond its aesthetic appeal, the Halloween Hermit Crab also plays a crucial role in maintaining a healthy aquarium environment. It helps clean up any leftover food on the substrate and efficiently eats algae, including green hair algae and cyanobacteria. In addition, the Halloween Hermit Crab is known to aerate the aquarium substrate by sifting through the sand, making it an even more valuable asset. However, as it grows larger, it may accidentally disrupt rockwork or corals in reef aquariums, so it's important to be mindful of its size. It lives in abandoned snail or triton shells and may even attack and eat a snail to use its shell as a new home. To prevent this, make sure to provide the Halloween Hermit Crab with empty shells of varying shapes and sizes. If there isn't enough algae present in the aquarium, the Halloween Hermit Crab will need to be fed dried seaweed as well as meaty items like mysis shrimp.

  • ORA Variegated Urchin (Lytechinus variegatus)

    ORA Variegated Urchin (Lytechinus variegatus)

    The Variegated Sea Urchin, Lytechinus variegatus, has been a popular invertebrate in saltwater aquariums for many years. Though these urchins have previously been captive bred for research purposes, ORA is pleased to make these aquacultured urchins commercially available to the Aquarium Industry. The Variegated Sea Urchin, a type of pincushion urchin, originates from the tropical waters of the Western Atlantic and can usually be found roving shallow sea grass flats and other sandy substrates.  In the home aquarium, these urchins are extremely effective herbivores, rapidly consuming nuisance algae. Consequently, aquarists must be sure to provide supplementary macro algae if none is available in the aquarium. While roaming the aquarium these urchins will frequently display an interesting “covering behavior”.  Whether for camouflage or protection from UV radiation they can be observed holding onto small rocks, shells, and pieces of macro algae with their tube feet.  ORA Variegated Sea Urchins will certainly be a hard working and beneficial addition to any aquarium.

    *Discounts Cannot be applied to inverts* Peaceful reef-friendly snail. An essential part of the clean-up crew Grazes on algae. Diet can be supplemented with blanched spinach or lettuce, and vegetable based tablet foods     Inverts will ship with your next day order*   The Trochus Snail, scientifically known as Trochus spp., is a marine gastropod mollusk belonging to the family Trochidae. It is a popular and widely distributed species found in tropical and subtropical waters of the Indo-Pacific region, including the Red Sea, the Great Barrier Reef, and the Hawaiian Islands. The Trochus Snail has a distinctive shell that is conical in shape and typically measures around 3 to 5 centimeters in diameter. The shell is characterized by a series of spiral ridges or bands, giving the snail its common name. The coloration of the shell can vary but often features alternating bands of white, black, brown, or gray. This snail species is highly valued in the aquarium trade and is sought after for its beneficial traits. It is known as an efficient algae eater, which makes it a valuable addition to reef aquariums. The Trochus Snail is particularly effective at consuming hair algae and other undesirable forms of algae, helping to maintain a clean and healthy aquarium environment. In terms of behavior, the Trochus Snail is a slow-moving creature that uses a muscular foot to glide along surfaces and forage for food. It possesses a rasping radula, a specialized feeding organ that enables it to scrape algae and detritus from rocks and other substrates. These snails are generally peaceful and can coexist with a variety of other reef inhabitants. In their natural habitat, Trochus Snails are typically found in shallow waters and intertidal zones, where they graze on algae-covered rocks and coral reefs. They play a crucial role in maintaining the ecological balance of these marine ecosystems by controlling the growth of algae and preventing its overgrowth. It's worth noting that there are several species within the genus Trochus that are commonly referred to as Trochus Snails, and their specific characteristics may vary slightly. However, the general description provided above applies to most members of this group.

  • Sale -50% Yellow Sea Cucumber

    Yellow Sea Cucumber

    Originating from the Indian Ocean, the Yellow Sea Cucumber boasts a stunning appearance with its vibrant yellow hue and elongated body adorned with spiky projections. During feeding, it extends its branch-like arms into the current, making it a captivating sight in an established reef aquarium. To thrive, the Yellow Sea Cucumber necessitates live rock to obtain essential nutrients, typically favoring areas with moderate to strong currents. As a filter-feeder akin to the Sea Apple, it relies on a diet rich in liquid or dried phyto and zooplankton, benefitting from regular substrate stirring to release bacteria and detritus into the water. Under favorable conditions, this species may spawn in captivity or reproduce by splitting into two individuals, reflecting both stress and robust health. However, malnutrition can lead to a decrease in size and loss of feeding arms, signaling the need for increased feedings with suitable food. It's imperative to maintain low nitrate levels and avoid copper-based medications, as the Yellow Sea Cucumber is intolerant to such conditions. When considering purchase, sizes vary, with small specimens ranging from 1/2" to 1-1/4" and mediums from 1-1/4" to 2".
