The Red Tail Cardinalfish (Apogon sp.) can be found among the shallow and mid-level reefs of the Philippines. They hide among caves and rockwork by day, then hunt from small benthic invertebrates by night. Their red coloration helps prevent being detected by predators and prey alike. They reach a maximum size of 3 inches and would do well in an aquarium of at least 20 gallons. They do well in reef tanks and should be fed a mixed carnivorous diet. Cardinalfish should not be housed with larger predatory fish or small prized invertebrates.
