Yellow Spotted Scorpion - Synanceia sp.

The Yellowspotted Scorpionfish (Sebastapistes cyanostigma) has a mottled red body dusted with tiny yellow spots. It also has yellow around its face and into the fins. 

Lionfish and Scorpionfish are perhaps best known for the venomous spines in their dorsal and pectoral fins. The sharp spines are used by the fish to ward off predators. While special consideration should be given before placing one of these predators in your home aquarium, they are some of the most stunning and desired fish in the aquarium trade. Fish in this family vary greatly in appearance, even between individuals of the same species. Many lionfish and scorpionfish are colored and shaped to blend in with rockwork, sponges, algae and other parts of the reefs they inhabit. 

These fish are voracious predators. Most species will wait for potential prey to come close before snatching it for a meal. Some, like the popular Volitan Lionfish, may actively stalk their prey. Lionfish and Scorpionfish can be fed a variety of frozen and prepared meaty foods like shrimp, clams, scallops, krill and other similar foods, but some may need live food like small feeder fish or ghost shrimp to trigger a feeding response. Those that dwell in rock or on the bottom of the aquarium may need to be target fed with tongs or a feeding stick to make sure they get adequate amounts of food.  

These fish are generally safe in reef aquariums as they do not eat corals or polyps, but take extra care to know where the fish is located as they may blend in very well with the rocks and corals. Do not keep these fish with shrimp, crabs or fish small enough to be eaten.
