I got a group of lovely longfin pink danios (aka red or ghost) from Aquarium Central in Edmonton (so jealous they had lots of fish I haven't see in calgary and were reasonably priced, also the tank section in Big Als is twice the size of calgary's!)
Can't get a picture but they look like this

He picked me out 5 female and 3 males (mostly long fins, but a couple regular) including two very fat ones full of eggs.
I have never bred egg layers so I did some googling and my first two attempts were a no go. But am trying again tonight with some changes.
I have a 10 gallon with an established filter, heater and half full of clean water. Large gravel/small rocks on the bottom. few chunks of java moss. Also a water pump to create a bit of current. Temperature is about 24 degrees.
I have kept the males and females separate and have been feeding them several times a day, mostly a frozen brines shrimp/mix, and a bit of flake food.
I put the two super fat females in the 10 gal this afternoon, this evening in the dark I added the three males. I have it in a south facing room with the curtains pulled back and have set the timer to turn the lights on around 6am.
I hope it works this time!
If not, any specific changes I could make for next time? The only thing I would really not like to do is live food.
