@StPatrick89, 'Yes'-- if you at least want to increase your chances of a successful outcome, an odd number will likely work best. And I like your idea of "3" because honestly, again, except for in a very large tank, 10 will turn in to 3. (And these are no longer $3.99 fish, from what I can tell these days.) Best wishes, and keep us updated on your personal experience.
