Corallimorph Pets • Corallimorphs require regular feeding with chopped shrimp, mysis, worms, pulverized fish food, mussel, fish roe, or plankton substitutes such as brine shrimp and Daphnia
Elephant Ear Corralimorph • The Elephant Ear is probably one of the most unusual corals available • They are like the Venus Flytrap plant in animal form. Looking like an anemone, they attract small fish, especially small anemone fish but other fish as well, to take refuge in their oral disk • Disk doesn't sting them like most anemones would but it slowly closes on the fish until it cannot escape • Mouth opens and consumes the fish • Suspected that the anemone secretes a drug which tranquilizes the fish and keeps it from trying to escape
Types • The elephant ear is usually cream colored or light grey, sometimes they have a greenish cast to them • Size up to 44 cm in diameter (usually 20-25 cm) • Tenacle free area just inside the edge of the disc.
Blue Mushroom Anemone • These corals come in many different colors like blue, red, green, brown, purple and often have stripes, spots, and mottled color variations • Favorite in aquarium collections due to diverse color & beauty
