Do you have a LFS that will take them? I've been there with guppies. Started with 2, ended up with hundreds over a few years. And I spent lots of time separating them, but never soon enough to get them all in time. Fortunately, I have a great local shop that bailed me out when I tired of them and moved on to other fish.
It's been years since I've had them and it was fun for quite a while. I still get tempted but I resist.
