I have a 15 gallon column tank. There are 3 young mollies in it.
Silver molly 1.5" Male
Dalmatian Molly female 1.5-2"
Balloon Belly Molly about an inch.
It has been running and cycled for a little over 2 months now. They are young mollies have had them for about 4 months.
Yesterday they were very active, the only addition was a new 100 W thermometer last night. When I checked on them this morning the temperature was near or slightly over 80 degree. The Ammonia/Nitrite was 0 but Nitrate was high. but the mollies were swimming HARD in place clustered at the bottom of the tank.
I have done 3 PWC since. To get the Nitrate lower. Now since all these PWC the 2 bigger mollies (silver and dalmatian mollies are now breathing "barley" lying on the bottom of the tank. I think the Dalmation molly is gone if it's alive it is 5-10% living. Now the Silver molly is at the bottom breathing but not moving and the little balloon belly molly is swimming hard in place in the corner.
My pH is also normal around 8 that is what we have here and how it has been since we have had them. We got them from neighbors who had fish.
Please help
