Baby CPDs

While looking into one of my tanks a couple of days ago, I noticed a tiny fish darting about near the surface, only a few millimetres long. I realised it had to be a Celestial Pearl Danio (CPD) as the only other fish in that tank are Salt and Pepper corys (plus shrimps). After feeding the tank with the very fine granules which I use for the CPDs I managed to see 3 little ones feeding at the same time and so there are at least 3.

The only other fish that have bred in my tanks were the Ruby barbs where two little ones managed to survive last year. I doubt if they will succeed again as there are now 10 Green Tiger barbs in the tank as well as the  10 Ruby barbs. I call it the greedy tank and I can't imagine any eggs surviving.

I attribute these unplanned breeding successes to something most people seem to hate, i.e. filamentous algae a.k.a blanket weed. I tend to leave this to grow and pull out a handful every so often, a good way to get rid of nitrates. I'm pretty sure this is the only place that a few eggs could manage to fall and be hidden long enough to survive, plus it provides a good place for the hatchlings to stay and there are probably suitable small food organisms there as well.

Anyway, I was wondering which species other people have found to breed spontaneously in their tanks, excluding livebearers, and if they have been successful in rearing them.

Just wanted to say congrats on the CPDs Richard. I've not had any breeding successes yet, though haven't made any effort (or conscious non-effort!) to breed fish yet. Given my greedy platies I'm not holding out much hope in this setup!

Grats on the CPDs Richard, they're beautiful fish
