![]() ![]() Pethia reval is a newly described highly threatened, fish species endemic to Sri Lanka. Most of them are collected from their natural habitats, wild population are depleting. Analysis of variance (One Way ANOVA) showed vermicompost worm group performed significantly (P<0.001) well in growth of angelfish and regression analysis resulted a good relationship between growth and the period of growth for all treatments.Įndemic fish species contribute 4% of the total freshwater ornamental fish exports in Sri Lanka. Tubifex worms, vermicompost worms, bloodworms and formulated feed as control were administered for experimental fishes for a period of 90 days and growth in terms of total length, standard length(cm) and weight(gm) were assessed in 30 days interval. Growth in terms of morphometric measurements was assessed for angel fishes grown in aquarium glass tanks of standard size fed different worm diet ingredients. An experiment was set up to record the effect of differenent worm diets in the growth of Angel fish (Pterophyllum scalare), a most accepted species of ornamental fish globally. ![]() Feeding the young ones with live feeds are essential for better growth and coloration. Diet forms the major input and one among the factors that controls growth of any organism under controlled conditions. ![]()
