Frogspawn corals are classified as large polyp stony corals (LPS). These corals are a popular and commonly kept species in many marine tanks. Fimbriaphyllia divisa (formerly Euphyllia divisa) corals have a corallite skeleton with a "wall" structure. Fimbriaphyllia paradivisa corals (Branching Frogspawn) have a tree-like branching structure with separate corallites or "heads." Both have polyps covered in the circular knobs that make Frogspawn identifiable. Frogspawn corals appear in shades of green, tan, and pink with contrasting tentacle knobs in pink, lavender, white, or cream. Overall, the appearance is reminiscent of amphibian eggs.
When placing your Frogspawn coral, moderation is the key. Frogspawn corals prefer moderate light. Lighting that is too bright can quickly lead to bleaching, while lighting that is too low can cause starvation. We recommend 100-125 PAR. Bear in mind that many corals can be gradually acclimated to lighting beyond their normal range. Frogspawn corals also require moderate waterflow. Currents that are too high can damage their polyps, while currents that are too low aren't acceptable for harvesting resources.
Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients. Frogspawn corals benefit from targeted feeding with meaty foods such as brine shrimp or krill.
When introducing a new Frogspawn coral into your reef tank, please know that these corals can be pretty aggressive and have a bit of reach advantage. They have sweeper tentacles that will sting neighboring corals. These sweeper tentacles, ranging in length from 2-10 inches) usually make their appearance at night. The good news is that most Fimbriaphyllia typically get along well together. Consider placing your Fimbriaphyllia corals in the same area of your reef tank to allow for different types of corals to inhabit other spaces.
