Note:

**What size aquarium should I buy?
**The answer to this question is simple… buy the largest tank that you can afford and house. Contrary to what you may believe… large tanks are easier to maintain than smaller tanks. The more water you have… the less chance there is that something will go wrong. Trust me on this one!
