Blue Marble pair

[Mugwump]

goodie, goodie, goodie, you poor dear.  If one has the thingamabob, others are het for it

not necessari

It's a simple recessive, Mug.  If your blue marbles come from the same parents, the gene is here, waiting to pop up when you least want to see it. 

It's a fun gene because either they don't hatch, the parents cull them for you as they free swim, bad ones are easy to spot and do in yourself, and you're left with the strong ones. What's not good about that?

That's the thing, marble is an incomplete dominant and will express in single dose, so the fry could have easily come from different pairs....or the same pair, and if they were both 'het' there will be a percentage of 'clean' fry....50% would be pearls, 25% would be 'het', and 25% would be clean...
Looking at the six that I received, only one (maybe two?) are pearl....a couple do look clean tho?? We'll see....

Here's a couple pics.....one shows a possible pair....the other looks like the female, who is a pearl....tho it shows up more in the 'pair' pic (lower)....the pearl takes on a 'blue' cast too it in the right light,,,interesting..... ...I could almost like that...LOL...note that the flash washes the blue out....drats......but still picks up the red eyes....

Thanks Pauline, when they first arrived a quarter+ size, I wondered how they would grow out as adults...now that they're almost grown the color, and size, please me a lot.
