I have some more questions (if you could imagine that). I'm thinking of eventually filling out the rest of my 26g tank with guppies. I have two emerald cories and three zebra danios. I would also like to get a sunset dwarf gourami as my centerpiece fish. I was thinking of getting three more danios and then nine guppies. At the LFS it said that the guppies would grow to 1.5 inches. Does it sound like that will be over crowding my tank?
