I recently acquired some YKK's (might be TT x KK mix?) and they've been fine for over a week now.
I have play sand as substrate, ~150 TDS, 5 GH, ~ 4.5? KH, pH 7.5+, and so far no deaths. They aren't breeding, either, but then again, the adults I received are all males and the juveniles? Don't know. I haven't been keeping track of the temperature of the tank, but right now it's sitting at 69°.
They came from a tank with a buffering substrate and remineralized RO so different water parameters... pH 6.2 to 6.5 gh 4 to 5 kh 0 tds 150 to 175.
Would definitely recommend lowering the temperature! And possibly lower your parameters just a tad?
What substrate are you using?
