I've had the fish under 6 weeks and it's about 6 inches long. I have it in a 180g tank with my Saratoga, Petenia and 3 large Plecos. He is the smallest fish in the tank and may be just acclimatising. It's just the feeding thing that worries me, I know the fish does come out at night looking for food but with the plecos anything on the bottom is there's also.johnuskglass;2367377;2367377 said:How long have you had him? What other kinds of fish are in the tank? I've been pretty lucky so far with mine coming out, but it took some time for him to get use to the tank. Lots of plants/lots of cover so he/she can easily hid from place to place helps, and makes them feel more secure. With mine sized mattered too - once he was bigger than the other fish, he was a lot more willing to come out.
My experience with these guys has been when their hungry, they'll let you know.
