Male Molly Died! Why?

[ChilDawg]

Um, upon re-reading the initial post...thanks for reminding us of the Betta part of the post, Wetman...why would she have fry without a male around?

I took my female betta out of my tank and put it in a 5 gallon because she should give birth soon. So my male molly was in the 37gallon without any other mollies and I just found him dead. Why is this?

It would really help if you could post the water parameters of your 37 gallon tank...pH, temperature, ammonia, nitrite, nitrate, hardness. How long was this tank established? What kind of filtration do you have? Were there any other tankmates? Did the molly display any symptoms of disease prior to death? Your maintenance routine (eg How much water do you change and how often, the fish's diet, etc).

I would also not rule out the possibility that some kind of contaminant entered your tank. Toxins from some household products could have entered your water column in some fashion. If your molly was behaving normally, and then died suddenly, that usually indicates some kind of toxic poisoning.
