The Freshwater Angelfish stands out for being one of the most beautiful, best-selling and also most popular ornamental fish of tropical waters. Its cultivation is concentrated in the southeastern and southern regions of Brazil, so reproduction of this species in other areas can become a profitable venture. The present study analyzed the economic viability of the cultivation of the Freshwater Angelfish, Pterophyllum scalare, in a water recirculation system. To measure the market demand, an interview was conducted with the main tenants in the industry, adding to the estimate. The profitability of the venture was 2,65% in the first year and 11,95% in the second to the tenth year and the payback rate was 38 months or 3 years and 2 months. Small-scale farming proved to be economically viable, presenting attractive profitability indicators compared to other aquaculture enterprises.
