this my 20 cm gbb. just started to tan him for the past two days with t5 lamp. my arowana was paler before and now it becomes more gold. i could still see some blue coloration on the scales when the light shine through it. for diet, i use crickets and superworm. i dont use backround for the aquarium, but next to the aquarium glass is a white colored wall. am in on the right track?
