Hello,

I've just had a shock - or at least as much of one as three tiny fish babies can produce - when I spotted them in my theoretically all male platy tank.

The context here, however, is that a couple of months ago I got two platies, knowing nothing about sexing them. When I realised that I had a male and female, and that I could end up with an out of control fish population, I returned the obvious female to the pet store exactly one week ago and came back with what I believed to be males based on:

So I now have three moderately sized theoretically male platies... But also three babies.

How could this have happened? Is there any chance that they were left with me a week ago by the now departed female and were just too small to notice for a week (I find this somewhat hard to believe unless they are practically microscopic to begin with - given they still look tiny and semi transparent now)? Or is one of my fish a female with a weird looking anal fin?

Here is a photo of the two with the most convincing gonopodiums:

And here are some of the other one (dark orange) that I'm now suspecting may be a secret female based on a smaller-than-the-other-two-thing-that-might-or-might-not-be-a-gonopodium!

One person I've shown these pictures to thinks all three are males, but I'd be grateful for more views.

I know this is completely off topic, but I would add live plants, or get some fake plants, I just feel like there's not enough in there. We will see if anyone agrees. Btw what I just said won't help with your situation but its still a bit of a problem :^)

It’s not my main tank - just where I was quarantining some. I also just took a few things out so these unwanted fry have fewer places to hide.

Thanks! I'd rather have a mystery than regular breeding issues. Guess my dear departed female just left a couple of babies as a leaving present/revenge for sending her back!

Wouldn't be surprised at all if those fry were from that departed female. Not always are fry very noticeable in a tank.

You're telling me. I thought I might have been down to 1 out of the 3, but I gave the one remaining ornament a nudge and found all three alive and well. Beginning to think the three adults aren't going to gobble them up, which is a bit of a pain (much as I wish I had infinite room for them).
