Frogfish are often forgotten because they are perfectly camouflaged whether on the sand bed or tucked within the coral reef, waiting patiently for their next meal.  They are ambush predators and they will eat just about anything passing by.   Depending on the species and environment, Frogfish can be intensely colored (living on a coral reef) or very blandly colored (living on a rock reef or sand bed).  Frogfish are compatible with most other same size or larger fish.
