The Fisheries Faculty of Konkan agricultural university has formulated as aquarium fish food (Flake form) "FIFOO" (Trade name) which was tasted on fishes like Guppy, Molly, Swordtail, Goldfishes etc. with very promising results. The feed is regularly marketed. The feed is in two colours - natural and red coloured (with permissible additive - Tomato Red of Asian Colour Company). To find out the efficacy of this fish food is rearing of juveniles of prawns. In one month duration preliminary experiment was conducted in all glass aquarium tanks. Experimental ":FIFOO" was in the form of flakes and pellets (1.0mm size). Clams meat was used as control feed. Feed conversion ratio (FCR) and survival % of prawn juvenile of Macrobrachium roserthergii was observed and also important observations like water quality parameters are also recorded in this paper. The result indicate that acceptance / preference of red coloured pellet feed were more in freshwater prawn which was calculated in terms of FCR and was found 2.0. The more acceptances for red coloured feed (Flake form) was also observed in case of aquarium fishes (Kovale et al. 2003).
