The Blue Sponge (Haliclona sp. on Scleractinia) is a peaceful species that is reef-safe, admired for its brilliant blue coloration, unique porous structure, and encrusting growth pattern. Unlike fish, sponges do not have separate male and female sexes in a way aquarists typically observe; instead, they are capable of both sexual and asexual reproduction.
They reach about 8–12 inches (depending on colony growth) and should be housed in aquariums of at least 30 gallons with ample live rock for attachment and shaded areas. Sponges require stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4) and must never be exposed to air, as trapped air bubbles can damage their internal canal system.
Provide live rock structures, shaded crevices, and gentle water flow that delivers dissolved nutrients and plankton. They do not require a sandbed or open swimming space but benefit from a well-established reef tank with stable nutrient levels.
Diet should consist of dissolved organic matter, phytoplankton, bacterioplankton, and other microscopic foods introduced via target feeding or natural water column plankton. They do not consume mysis, brine, pellets, or algae directly like fish.
With proper care, this invertebrate makes a standout addition to the aquarium, serving as both a natural filter and a striking splash of color in reef aquascaping.
International Aquatics Quarantine & Guarantee: All fish are checked by marine vets, given a formalin bath, and held for 14 days in copper-treated systems. We feed Selcon-soaked food with Kanaplex and Metroplex during quarantine. Unless marked, all livestock comes with our 15-Day Guarantee. You will receive a video of your fish eating before shipment. On request, we also send photos/videos after arrival at IA. Some species are import-to-order (3-10 business days). Many common species are already cleared or near the end of QT.
Several species will be import-to-order and may take anywhere from 3-10 business days to secure. Once your fish is secured, you will be notified, and the quarantine process will then begin.
