I bought a Jd from a local fish farm and he doesn't look like a normal Jd he looks more like a EBJD other then his face and tale. Could he be a BGJD and thats why hes so blue ?
When I bought my smaller JD, the sticker on tak and sales ppl said it was a 'dwarf JackD'. So maybe it's older than you might think it is, and that's why it's has all the coloring already? It's a real pretty fish!
