well it's very hard (imo) to determine what strain this is. i am not an expert, as jplikewhoa likes to refer to himself as, but i think it may be a golden base that hasn't turned gold yet. i have one that looked something like that until it recently started to turn. or it could be a vieja mix. i think if you put some really colorful gravel in there, and a nice colorful backround, the fish will become more colorful also, and be easier to identify.
