I'm at work and got a text from my wife telling me one of the mollies was dead floating at the top. I'm afraid the larger goldfish might have nipped at her. Planning on getting rid of the gold fish. Will be doing water test and change later today. The other fish appear to be doing fine no signs. I'm really new to this so be nice FYI 10 gallon tank water parameters last checked were within normal range temp is appropriate.
