New aquarium owner
I am new to the hobby. I have a 10 gallon tank with plants, a snail, 3 tetras and 4 white clouds. Oh, I also have an african dwarf frog. Last year, I had a small aquarium with just a couple of goldfish, a frog and snail. I had it for weeks. Then I decided to put a heater because the weather started to get cold. The next day, the fishes and the snail were dead, and the frog had escaped. Can anyone tell me what might have happened?
