Yes, if you have a 125 gallon aquarium, you could do it once a month, but unless you have a drastically understocked NPT, I would stick to weekly changes. I'm not too good with remembering the stuff, but I think the waste will overload the filter bacteria or something. Neons can be nip, especially with long fins, in a small tank, Ember Tetras would be better, like Bomb said. Cories could work, but they absolutely need at least 3. They'll be happier with 5, but they can live a full, natural life with 3. Harlequin Rasboras are good, Platies are a personal favorite of mine, they're like mollies a little, except stay smaller and don't need salt. In a 10 gallon with appropriate filtration, you could do 3. Make sure they're either all female or all male, they breed like rabbits.
