how many more fish would be okay to have in there? it's a 10 gallon, and there are already 2 guppies, 2 danios, and a baby molly in there. i know that it should only be one at a time but what's the maximum and safest? Is the one inch per gallon a good rule?
Oh, and I got some drift wood and a rock for xmas, hope they dont mess up things.
