Translucent Angel babies

[accidentalbreeder]

Hi, I have become an accidental breeder of angels. My koi girl and pearl boy paired up in a community tank and after laying eggs twice and terrorising all the other fish, I moved them into their own tank. Anyway, they laid that same day and I ended up with lots of babies. The babies are now 3-4 weeks old (and I’ve just moved them into their own tank after mum laid again and dad killed around 20 of the babies), and some of the babies are translucent (you can see their innards). The others still appear fairly pale to me. Is this normal for their age?

That's quite interesting and funny the way you have put it-"the breeder"
