Hello, my umbee, probably around 6 inches by now still kinda not that much going on with him. So at what size will they start to colour up? I guess it's a male since it grows very fast. Maybe because I don't have aquarium light for it? Cuz I keep it in a pond, soft white sand as substrate, lots of caves, sunken logs, lots of plants, such as epiphytes, lots of dried leaves on the floor and lots of floating plants. The only light it gets is natural sunlight in the morning.
