The Apistogramma Trifasciatum a cave spawning Dwarf Cichlid, they are a very peaceful variety of cichlid and can be kept with most fishes. They grow to about 5 cm and is similar to the other apistogrammas except its not as colourful as the rest. Most people buy this fish for its lush blue high dorsal fin, which has a nice blue shine to it. As well as its light blue shding on its body.
The requirements for this fish are the same as most Apistogrammas - well filtered, slow moving soft water; hiding places, a variety of foods, and plants, wood, or rocks to break up their line of sight - but this species seems to thrive and breed at a wider pH and GH range than other Apistos. They are harem breeders, so you should keep 1 male to 2 or more females. Wild specimens may only accept live foods, but tank raised fish eat pretty much anything. Tank mates should be small and non-aggressive. I've kept them with tetras, killifish, otos, and corydoras without incident, except during breeding when the corys get knocked around a little bit (nothing serious though).
