It has now been introduced widely elsewhere East Africa, and is believed to have negative ecological impact, particularly on native tilapias. This species is reported to reach a standard length of up to 36.3 cm (14.3 in), but is usually much smaller. It is exploited by small-scale fishery and aquaculture operations.
