Yellow / Red / Orange

Yellow / Red / Orange Sponge (Axinella sp.) is a peaceful species that is reef-safe, admired for its bright coloration, branching structure, and unique filter-feeding nature. Males and females are not visually distinct, and juveniles appear as smaller encrusting or branching forms before developing their full sponge structure. They reach about 6–12 inches depending on growth and should be housed in aquariums of at least 30 gallons.

Provide ample live rock for attachment, shaded areas away from direct light, and stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4). Unlike fish, sponges are sessile and do not require a lid.

Diet should consist of dissolved organics, phytoplankton, and specialized sponge/reef supplements, as they are filter-feeders relying on microscopic food in the water column. With proper care and a nutrient-rich, stable reef system, this sponge makes a standout and vibrant addition to the aquarium.

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.
