I seem to have a problem keeping Mollies alive.
It got so bad that I quit buying them as I couldn't keep them alive for more than a few days. When I upgraded to my current tank I decided to give it another shot. I purchased 6 and had 4 die within a few days. One of the remaining two got tail rot (successfully treated and now doing well
) Those 4 that died were due to my error of adding too many fish too quickly (I didn't know better at the time and lost about 10 fish in 3 days
Since I have been able to keep those 2 remaining mollies alive, I decided to give it another shot. Two days ago I bought 2 dalmatian mollies and 2 platys (as well as several more live plants). This morning when I woke up, everyone seemed fine. This afternoon, one of my dalmatian mollies had died
My water chemistry was tested hours before putting them in: pH 7.4, ammonia 0, nitrIte 0, nitrAte 10, GH 11, Kh 4
Current water chemistry (just after taking the dead molly out): pH 7.4, ammonia 0.25, nitrIte 0, NitrAte 5, GH 12, KH 4.
I have always heard that mollies are sturdy fish. Any ideas as to why mine keep dying?
Thanks in advance for any information.
