Well, I've had these guys for... a good while now. They just don't seem to be growing!
A while back I had a guy e-mail through the JD profile on the website, asking if anyone knew anything about blue JDs. I told him I personally have 5 of them (my dad killed one when I was on holday /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />) and he asked if I'd had any problems with them not seeming to grow. It didn't appear so at the time but now I have one fish that must be 5" TL and the rest are barely above 3" TL. That's after, hmm, a year?
They seemed to grow pretty quickly to begin with but in the past two or three months they've barely grown at all - I'm feeding them twice a day too...
Could this be a genetic weakness or something? Obviously it doesn't happen to all specimens as I'm sure we've all seen a blue JD at about 8 or 10" TL.

I think it could well be genetic Dunc, they are either been mass produced for shops which comes with its own complications or a lot of shops are buying in tank bred stock but the problem is a lot of these tank bred fish are produced from fish bought at the same time so there is a good chance of inbreeding.
I saw some in a shop on Saturday that were little over an inch but if you had seen them in a photo with nothing for size reference you would have sworn they were 6"+, they just looked like old fish in miniature /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

I honestly thought I'd stated how much I'd fed them, but when I've looked back, I somehow managed to leave it out... /laugh.gif" style="vertical-align:middle" emoid="" border="0" alt="laugh.gif" />
I feed them twice a day - usually once on dry and once on a fairly wide variety of frozen foods. There's never any foods left over.
Water changes are once every 7 to 14 days depending on schedule.
