Conteúdo: | Due to the economic potential of Hypancistrus zebra in the ornamental fish market and its current classification as an endangered species in its natural occurrence sites, the present study sought to determine a suitable feed management strategy and stocking density to allow for an adequate captivity maintenance of this fish species. Three experiments were conducted as follows: (1) feed preference (artemia Artemiasp., shrimp Litopenaeus vannamei, fish Cynoscion spp. or mussel Perna perna); (2) de&#8208;termination of feeding rate (5% and 10% live weight day&#8722;1) and frequency (1, 2 or 3 meals. Day&#8722;1); and (3) evaluation of stocking density (0.25, 0.50, 1.00 and 2.00 g/L). Zebra pleco did not present the characteristic buccal scraping behaviour on the feed, commonly seen in other Loricariids. Artemia was the preferred diet followed by fish, shrimp and mussels. The frequency of two daily meals and the feeding rate of 10% live weight day&#8722;1 allowed for an improved zootechnical performance. Zebra pleco showed enhanced specific growth rate at the density of 2 g/L. Our results suggest that, to improve the zebra pleco rearing conditions, it should be maintained at a den&#8208;sity of 2 g/L, fed two daily meals at a feeding rate of 10% live weight day&#8722;1. These findings correspond to useful information for an adequate management of this spe&#8208;cies and could assist in the supply of healthy specimens to the ornamental fish market as well for the restocking of declining wild population
