Been breeding fine, although am having an issue with losing adults here and there. Have increased GH to 5 and TDS to about 154, and plan to raise it further.
In a larger tank (90+ g), the water parameters are something like this....
pH 7.6
High pH 7.4
Ammonia 0
Nitrite 0
Nitrate 0
KH 3
GH 3
TDS 102
So not much different at all... And *extremely limited* success... as in, plenty of berried females, no babies! Or the babies disappear after 1-2 days. Have had at least two make it to a month old. One of those, and possibly a third, may have made it to 2+ months old now?
Which is interesting because the larger tank has been set up and running for I don't know how long over a year. I've only known of the tank for just over a years time now. In comparison, the 20H that the cherries are breeding in has been set up going on 2 months now and the used HOB filter (after being cleaned and adding new media) is going on 3 months. The oldest babies in there are just about as old as the tank is.
