Hay all, I am planning on upgrading from a ten gal to a thirty gal and was wondering if this would be ok: 2X platties 2X mollies 6X guppies I am also intrested in more species if I have A. more space or B. its a better combination. Also I currently have 3 male guppies so should I go with three more males, three females, or more than three females. I would love to use my ten gallon as a home for fry, a hospital, or a quarantine tank. Which would be best? Thanks!
