Some people put a pair (1m,1f) together, others a trio(1m, 2f). Hard to tell which works best, as I have had success both ways. With a trio you might get one of the females eating eggs.
As far as how many eggs, there's no hard and fast rule. With the Gardneri Blues, I've probably averaged 6-10 egss a day over a week. Some days there were none and the next there could be 15.
I generally collect eggs for a week, store them on peat (floating in a container in the tank) and wet them 10 days after that.
The other way, is to float a container of water with Meth Blue in the tank and store the eggs until they hatch in about 14 days.
I can show you exactly how I do things when you come around.
I am certainly no expert and have learnt alot from Alanmin4304 and Barrie. These guys have a wealth of knowledge.
Also join the Killie club and this will give you alot more access to different Killies,cheap food and knowledge.
Keep in touch over the next week and we can maybe organise pick up next Saturday afternoon?
