Abstract: This study was conducted to compare effects of aquria made of glass or fiberglass on growth and pigmentation in goldfish, Carassius auratus (initial weight of 8.1 g) and electric yellow cichlid, Labidochromis caeruleus (initial weight of 0.47 g) for a rearing period of 80 days. Skin colour assessment was performed by reflectance spectroscopy with transformation into colour parameters based on tristimulus values, L (lightness), a (redness) and b (yellowness). A lower L and a higher a, b was obtained on skin of goldfish reared in fiberglass aquarium compared to those in glass one (p<0.05) while no differences were observed among L, a and b of electric yellow cichlid reared in glass or fiberglass aquarium (p>0.05). Growth performance, feed conversion ratio and survival ratio in both species were not affected by the aquarium types (p>0.05). Aquarium made of fiberglass should be preferred for goldfish rearing as skin colour is significantly improved in this media.
