I agree with the variety as stated above, but not with the quantity. I would start with half the numbers above and add more as needed. You should never purchase so many algea eating animals without being able to sustain their diets. Also, the common consensus on this board is to keep the animals that you purchase. Don't just use them and then send them packing! This is not to undermine Waterfaller1, she has great advice and this is my opinion after 8 years in the hobby.
