Can you expand on your “perferred method”? Sorry OP not trying to hijack your thread.
I have used this set-up for the past 4 or 5 years now with great success…..
5.5 US gallon tank with course black substrate and a large portion of live moss. A small sponge filter set at a very slow bubble, not much water movement. 3 female fish and 1 male in the tank for 5 to 7 days. Breeders are moved directly into another breeder set-up when removed. Within 2 weeks of removing breeders fry are present. Very simple but effective set-up.
