Endlers and white clouds come to mind....depends on the tank size....also, shrimp can tolerate a bit cooler water...but too low and they may not reproduce and/or die..same with plants...you want to keep the temp at least in the upper 60's
The breeder lives in a province far from where I am, and he rarely comes for a visit. He has a petshop here which a family member of his looks after. If they still don't breed they'll have to share a tank with my red eared slider turtle. lol
Spawning and rearing your own Bettas can be fun and rewarding.....it will get easier as you go....good that you are getting young fish they are much easier to spawn..she may need more time-you should contact the breeder and see if you can find out her age....
Thanks for the info! I will buy a new female today. The one i've got just always runs away and hides from the male. I've already paired her with 4 males and she just avoids them totally, even after a week being with them.
