The Guppy fry seem to have separated into 2 groups, except when I'm feeding them. I'd noticed a few days ago that there was a large variation in sizes and now we have half the fry at the bottom of the net and the larger fry swimming at the top. It only became noticeable because I moved the direction of the outflow of the filter, which meant that the fry were not getting as strong a blast as they had been.
It does look like most or all of the larger fry have gravid spots, whilst the smaller fry do seem to have the modified fin of the males. But it's funny to see the way they have separated themselves, but I suspect that I'm going to have to work out how to separate them shortly, else I'm going to be coming home to a dozen or more pregnant Guppies after my holiday (three weeks until I go...).
The sensible thing to do would be to get a small tank for the females and put those I'm not keeping in there - but I know what my wife would say... The fish are developing their colours well, and all seem to have their mother's eyes - totally, black, no white. They also have her black flecks on their tails, which are yellow (her's was red), which has probably come from my yellow tailed male.
It's a pity the other female lost her fry. They would have looked great as she is just a pale colour and should have taken his yellow well.
Also, we've finally let the Danio Fry loose into the main tank. He seemed to latch onto the Glass Bloodfin Tetras for some reason, and they didn't appreciate that. We darkened the room to give him plenty of time to settle in, but the lights were long since off, so hopefully he'll be OK on his first night in the full tank.
Maintenance - 'MadAlec' released to the main tank!
