I'm getting ready to upgrade from a 5.5 gallon to a 10 gallon tank and would like some advice on the number of occupants. My current tank has 3 male fancy guppies and 1 cory cat. I'd like to add more of both fish and also maybe a honey gourami and some ghost shrimp. Any advice on the numbers of each? I cetaintly want a happy and healthy community. Also, in adding more cories, to make them happy together do I need to stick to the same kind or will they be happy with a variation of kinds? Thanks in advance!!
