The Oscellated Frogfish (Fowlerichthys ocellatus), is a sedentary ambush predator. Growing to roughly a foot in length, and the fact it can swallow fish up to its own size, means tankmates must be chosen very carefully. They are masters at camoflage and use the antenna on their forehead to lure their prey in closer. These are rare to find locally, but come in different colors, black, orange, yellow and brown, etc.
