So I have this tank just sitting on the floor in the bedroom and I can't possibly think of what I could house in it, as it is only 1.5 gallons! Does anybody have any suggestions on what I could keep in it? A frog? Snail? Shrimp? Right now I own a goldfish [Ronald] and a pregnant guppy [Irvette]. After Irve gives birth in her 15 gallon tank, could I move her to the 1.5 gallon [heater and filter, no worries]? Thanks for all your suggestions, my fishy friends!
