fry are about 3 to 4 weeks old and all of a sudden dying fast. In weeks before lost 1 or 2 a week. Have not changed food or type of water conditioner. Everything seemed fine then a lot of dead ones.Sudden death of fry? I clean tank everyday and do 10% water change every other day.?Couldn't tell you without knowing a few things:
Did you make sure the water was the same temperature before adding it? Fry are extremely delicate
What kind of fish are we talking about here?
How much, and what, have you been feeding them?
Are you testing the water for ammonia/nitrites/nitrates?
Do you have a heater in their tank?Sudden death of fry? I clean tank everyday and do 10% water change every other day.?Check the ammonia, nitrate and nitrite levels. They should actually be perfect as it sounds like maybe you are changing the water too often. Not sure though, depends upon the bio load (number of fish/size of fish compared to water volume).Sudden death of fry? I clean tank everyday and do 10% water change every other day.?why are you cleaning and changing water so often? the natural cycle of the water may have been effected. there are certain friendly bacterias that you want to have in your tank and if you are cleaning every day and changing the water all the time, you aren't allowing them to grow.
