Soapfish Grouper

Soapfish Grouper (Rypticus sp.). It is a semi-aggressive species that is reef-safe with caution, admired for its unique defensive mucus secretion (soapy toxin), interesting coloration ranging from browns and yellows to spotted or striped patterns, and its close relation to groupers.

Males typically grow larger and may display stronger territorial behavior, while females/juveniles are smaller, often with more subdued coloration and less pronounced features. They reach about 8–12 inches in adult size and should be housed in aquariums of at least 100 gallons.

Provide ample live rock for hiding spots, caves, and overhangs, along with open swimming space. A sandbed is optional but can enhance their environment. Ensure stable water parameters (salinity ~1.020–1.025, temperature ~72–79°F, pH ~8.1–8.4), and use a secure lid since they may jump if startled.

Their diet should consist of meaty foods such as mysis shrimp, enriched brine shrimp, small pieces of fish or squid, krill, and high-quality carnivore pellets. With proper care, this fish makes a fascinating and unusual addition to marine aquariums, though it should not be kept with very small fish or delicate invertebrates due to its predatory nature.

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.
