They come in a wide variety of colour combinations with green and purple being the most common and orange and gold less widely available. Sometimes a single specimen will have two colours of polyps and these are often known as “Splatter Frogspawns”. Branching Frogspawn grow through either the splitting of one head into two or, less commonly, new branches sprouting from the central stalk.

Like other Euphyllia, Frogspawn are generally found at deeper depths, up to 130 feet. Consequently they do not need excessive amounts of light or flow to thrive. They are generally imported from the Great Barrier Reef but there is also a thriving aquaculture industry in Indonesia. In a reef tank they should be placed in the middle to upper third of the tank but they are generally fairly adaptable as long as they are given time to acclimate. They should be placed on exposed rock and given ample room, as they have potent stinging tentacles that can harm other corals. They can be placed on the substrate but don’t generally fair as well.

Frogspawn do best with moderate lighting and flow. If the lighting is too high the polyps may remain under inflated or even retract. Flow should be sufficient to gently sway the polyps but not so intense as to blow them around aggressively. Too much flow can even cause the polyps to tear. Like all Euphyllia, Frogspawn love to eat! While they can meet their energy needs through photosynthesis they will grow faster and have better colouration if they are fed once a week. An LPS pellet such as Vitalis makes a great choice. While Frogspawn have a fairly potent sting they can be placed in close proximity with other Frogspawn or Hammer corals. In fact, many hobbyists create beautiful Euphyllia gardens with Frogspawn and Hammers of various colours. While Torch Corals are also members of the Euphyllia family, they have been known to sting Frogspawn so care should be taken. As with all LPS corals it is important to monitor calcium and alkalinity levels and maintain them within
a stable range.
