sharing my sulawesi tank

[Draka]

Other than those I got from bro Matt, Sulawesi that I get from new shipments sometimes die regardless of good water parameters, but with the moult in a weird position.

Well, I did a check the day before this happened. NO2 and NO3 were pretty much at 0. gH, kH and pH seems optimal to me. Molting problems? Actually I have not seen any molting at all, or at least none that I could have seen since they have pretty decent cover to do whatever they need to do. Could this be the reason why?

Maybe you'll want to share the parameters readings?
