no other live food substitute has yet been used (Maeda & Hino 1991). Watanabe et al. (1983) and Tamaru et al. (1991) reported that fish larvae of 2 to 3mm should be fed with rotifers during the first 30 days until they reach 7 to 10mm length, and then fed them with a mix of copepods and cladocerans or Artemia nauplii. Once the larvae are 10mm long, the food could be fish flour, and larvae size ends when they reach 30 to 50mm. Degani (1993) found that juvenile angelfish increase growth adding live Artemia to different diets with high protein, he suggest Artemia con- tains a micro-element that is absent in artificial food. In the present paper the best growth was using live Artemia cysts as food, also survival was higher than using artificial food. Figueroa et al. (1977) found that angel- fish fed with D. pulex spawned between 857 and 959 eggs, whereas with “Wardley” (bal- ance food) spawning reached only 363 eggs. Survival was of 91% fed with D. pulex versus 62% fed with “Wardley”. In this work a similar food as “Wardley”, “Tetramin” was used. The results show less growth and higher mortality than using live food.
