I am Glad to have found this forum for communicating about my Aquarium and fish. I have had aquarium set ups and fish on and off since I was a kid. Usually 10 and 20 Gallon set ups. I just moved and set up a new 10 gallon aquarium. It started off rocky because of Amonia but a water change and new water treatment seems to have taken care of that. I suspect my black molly is Pregnant because she keeps swimming up and down in a vertical manner near the heater. Im excited if that is the case and look forward to enjoying it
