So I recently bought a 22l(5 gallon) fish tank for my 4 small Balloon Mollies that I purchased just 3 days ago. I understand that 5 gallons is too small of a tank for Mollies but when I bought them I was told that the size would be fine. I will be upgrading soon but will have to wait a month or so for the filter to be mature enough and cycle for when I put the fish in. Will they be ok until then?(I have attached a photo of it) the new tank will be an AquaOne, AquaNano 40 tank which is 12 gallons(55l) Dimensions:40cm X 40cm X 40cm, will this be enough for my growing fish? Please bear in mind that my fish are SMALL BALLOON Mollies and not in fact regular mollies which grow much larger. I will be keeping them as tropical fish by the way and they are all females so will not be breeding. That is all I will be putting in the tank except from a couple of RCS. Thanks in advance. This is my 5 gal one at the moment.
