Keeping mollies

[soleil1980]

Hi everyone!

I have a fully planted 60g with bushynoses, cories and a few guppies and tetras.

The tetras are left overs from my other tank I closed down.  I have been breeding plecos and guppies for a few hears and wanted to try mt hand at sailfin mollies.

So here is the thing... I have bought 1 sailfin molly, 3 black mollies and 3 silver mollies (the white ones).... They are all dead except one of the black mollies... Everyone else is doing fine and I do have baby plecos and guppies in there

I checked the water parameters and all is fine... Ph 6,5 (lots of driftwood) nitrate and nitrites 0, somewhat hard water...

So what am I doing wrong!?!?!?

I have kept kilifish, angels, swordtails other catfish and kribs without problem... I am confused

My research says Mollies like ph between 7-8. And placing a lot of driftwood in with them is not ideal as it lowers the ph. Now this doesn't mean that was what killed them, where they quarantined. They may have been ill before you got them.
