I jus recently purchased a Blood Red Parrot Cichlid and a tiger Oscar due due to the fact the the aquarium shop had them together and loved the look of the tank. My Parrot cichlid is maybe 4 inches in body and the tiger Oscar was about 2 to 3 in in length. I turned the lights off in the aquarium to reduce stress as I normally do when putting fish in an aquarium. But, when I went and checked on them maybe 6 hours later, I can't seem to find my tiger Oscar. Is it even possible that the parrot cichlid ate him, or is he just a good hider?
