I started with 2 Lyretail juveniles and one turned male. Every time I add more females they never make it. The male doesn't seem to want them. I tried adding 3 healthy strong females at a time with no luck. What do you think?
Usually adding more than what you already have works out, but if adding 3 to your duo isn't working, you could always try 4 or more, or just leave them as the two.
