Freshwater angelfish (Pterophyllum scalare) are common aquarium fish belonging to the family Cichlidae. This species is popular in the aquarium trade due to their aesthetic quality, with several different color morphs and fin lengths available. They grown via commercial aquaculture production; however, few empirical studies have been conducted, especially when considering larviculture. Larviculture of P. scalare often depends on Artemia spp. nauplii as a first feed, increasing production costs due to fluctuating cyst prices, limited availability, and labor-intensive culture maintenance. Reducing the use of live feeds can therefore streamline larviculture and increase cost efficiency, given that larval survival, growth, and quality are maintained. Liquid Artemia replacement diets are inert liquid diets that claim to mimic the smell, taste, and size of Artemia spp. nauplii while maintaining appropriate nutritional profiles. These diets have been used in shrimp aquaculture but have yet to be investigated for fish larviculture. Three trials were conducted to investigate the efficacy of replacing Artemia spp. nauplii with inert liquid diets. First, the performance of two brands of liquid diets, EZ Artemia and Liqualife, were compared in a 14-day trial. Next, the inclusion level of the liquid diet that best promoted larval growth, survival, and quality after 14 days from first feeding was investigated. Lastly, three timepoints (3, 6, and 9 days post-hatch) were selected to determine the effects of gradually weaning P. scalare from live feeds to a liquid diet. In general, larval fish did not perform well when fed liquid diets; larval survival was reflective of the inclusion rate of the liquid diet, regardless of the brand (Fig. 1). Overall, tanks fed diets the highest inclusion of live Artemia spp. had the highest larval survival. These results suggest that inert liquid diets may not be a suitable replacement for live feeds for P. scalare. Further research into Artemia spp. density requirements for this species is warranted.
