Here he was a couple of weeks ago, for comparison:

He's now roughly a month old and is eating a mix of liquifry, crushed pellet and daphnia. He's probably about a cm and a half long, and is getting rather fat...
At least his digestive system is working

NB. The bottom of the tank looks a little scuzzy-I'm scared to siphon that section too much in case Stephen goes up the tube!
Just wondered if anyone else can answer a couple of questions for me, as I'm totally new to this fish raising thing. At what age should I expect to see any colour? I recall that fry can often be brown or pink, is this right? Stephen has little black spots along his back and forehead, and also in his tail. Is this the start of calico coloration, or do all fry have these? Lastly, Stephen's tail is joined along the top seam, a little like a tosakin. Is this normal for fry or is he just a bit weird? Thank you!
