My new molly fish recently gave birth to around 15 babies. They are all in a separate baby tank thing that sits in the main tank and lets water circulate. Over the past few days, since they were born, around one or two babies have died each day. Today, four babies have died already.
We had only had the mollies for two days when it gave birth. Since then, three other fish in the tank have died: one siamese fighting fish and two guppies.
Please help me as I don't know what is happening!
Thanks
Tom

The first thought that come to mind it that this might not be a very mature tank. If it has only been running a month or less then your problem probably stems from ammonia or nitrite build up in the tank. If this is the case generous water changes will provide relief until the beneficial bacteria can become better established and provide the balance needed to maintain the tank in a healthy fashion.
If the above is not the case, we would need lots more info, such as size of the tank, water quality indicators (such as ammonia levels and pH) and a complete description of any symptoms you have noticed before even a reasonable guess could be made.
Hope that helps some

It sounds like you have some kind of illness in your tank. You wont want to do a complete water change, instead take a sample to a store that specializes in fish (only sells fish not a regular pet store) and ask them to test your water for something your test kit is missing. They should be able to tell you if the water is ok, and if it is not what to put in it to fix the problem. Also, check your heater to make sure it is working properly. Your water should be around 74 degrees if my memory serves me right (but check this with the fish store too) if it is too high or too low your fish will get sick from this as well. You may loose a few more fish before this is over, but the sooner you can treat the tank and make it healthy once again the better. Good luck. Fish are alot of fun and are pretty to watch, but they are hard to keep sometimes when your equipment fails or you add someone that is sick.

Could be anything really... Have you had the water in the tank established for at least 30 days? (The water has to go through the full amonia/nitrite/nitrate cycle) Have you added a small amount of salt to the tank (mollies especially love/need it). Is the pH of the water acceptable? Mollies are fairly delicate, and need very good water quality to survive. Good luck you fish murderer!

From what I've read raising Molly fry can be challenging. I'm on my second litter of fry and I've still had some die in a very mature and healthy tank. My silver molly Angel gave birth to approximately 100 on Saturday and it looks like I've lost roughly 30-40 fry. Her last litter was about 30 and I had 11 survive. I don't know if some are just born too weak to survive or if they fall victims to bigger fry. It does appear that it was the larger fry that survived.

Tom you need to check the pH balance sometime when one fish dies they build up ammonia and the water is contaminated, so you need to change about 3/4 of the tank water. Go buy a pH test kit if you don't already have one. Plus are you feeding the babies? If not then you need to.

Imkeep my molly fry in a 10 gallon tank. they are all colorations and sizes, as a week, a sparkling batch is born. I incredibly have found out no count what you do, some will die. I t made me unhappy on the commencing up, yet, i assume that's constantly the main useful who proceed to exist. sturdy success and shop doing all your water variations.

Bacterial bloom? What size tank is this? Did you let it cycle before you placed the fish in?

Change the water in the tank and make sure it is not stagnant and at the right temp.
