Cardinal baby survival

[ryantube]

My temp is 82F, pH 8.0-8.2, TDS is 270.
They have been there for a while and doing fine, but for some reason they disappeared one by one, until only 1 berried female left. Then she gave birth to 3-4 babies.

Clarify, it's Sulawesi cardinal, not Caridinal

They seem to be able to handle a wide variety of kH and gH, but I think in the lake they come from they are relatively low actually, below 4 for both. If you improve your condition baby survival should go up quite a bit. With all the problems I've heard about keeping Sulawes I am surprised they are doing as well as they are in your conditions.
