Danios

Question
My son and I have recently started up a freshwater 10gallon tank with heater and filter.  After cycling the tank, we added three danios (all of this recommended to us by PetSmart).  We woke up this morning to find only two Danios remaining.  There is no evidence anywhere of the missing fish. I've checked the filter, gravel and area surrounding the tank (which does have a lid). Any idea what happened here??  We are really puzzled!

Answer
Anne,

I have no idea what happened to your fish. If you have gravel and other things in the tank, it could be hiding. Other than that I am sorry I could not really answer your question. They are good at hiding and you might see it in a day or two.
