Bettas are tough, but even they can't do anything about their owner's stupidity.
There have been lots of changes today, I removed the dad (and mixed the whole tank during that, the daddy was really fast), added some food (and bacteria with it). And then, I accidentally dropped some water from melted bloodworms to the tank, right on top of the babies. And you know, I should know these things and be like the great breeder or something but in the end of the day I am just a stupid and clumsy girl
I carefully removed some water from the place I dropped the yucky, foul smelling water, but I have a bad feeling about this. Let's hope it doesn't kill the babies.

10 dead. This is a good lesson. You shouldn't mess with the water and tank too much (and I SHOULD already know this). It means trouble. I suppose these ones didn't die just because of the warm bloodworm water full of bacteria (people do feed fry with chopped bloodworms too, it's not a no no for them), but because of the whole day with lots of changes and stress. There might be more bacteria than normal in the water now.
Well, let's hope the others will survive. I will stop this worrying thing and let the nature do it's thing, of course I will feed them, but I will intefere as little as I can. If they survive, great, if they don't, well, there's always another change and another spawn.
Rest of the babies seem to be ok now.
