T. ruweti is a small, true Tilapia found in the far southeastern sections of the Congo River basin. It is famous as being the cichlid found in the Okvangu delta, a very unique habitat where the Zambezi River literally empties into a desert, creating an incredible oasis. Unfortunately, that aqua-oasis comes close to completely drying out every dry season, and if that were to happen the population of T. ruweti in that delta could disappear. That is why the fish is a priority species in the C.A.R.E.S. Preservation Program.
This diminutive cichlid is also one of the most well-suited Tilapines for a small aquarium. Adults rarely grow larger than 3″, and they are not overly aggressive, even when spawning. Breeding reports are few for this species. The trio I am working with act like they want to spawn, but so far… no luck. Hopefully soon….
