Sorry I haven't been on for a few days. The escapee is still about, I saw it last night. He/she always looks full of food so is finding plenty. I always squirt some in that corner though as it's staying put where it originally settled. I think it's too big to be eaten now but it's staying in it's spot which is good. They're 4 weeks old now, and they were 2 1/2 weeks when that one escaped.
I have one smaller than the others too. It always has been, but now it's bigger I can see that it has a very slight kink in it's spine and a flat spot on it's head. So we'll have to wait and see how that one does.
Ooo good luck with your new ones! Are there any more out? Once mine started they seemed to come out one after another apart from the first one which was well ahead of the others. I've had 2 more spawns since my lot. One from each female I think. One is darker than the other one so I can tell them apart. The darker one - which is the mother of my babies - is really good at hiding eggs. There were some that were there for a couple of days that looked fertile, but although the other fish didn't spot them, the snails got them.
