A. Our contracts range from as low as three months, all the way up to one year. This allows for the would-be client to customize a packaged deal that would work better for what they want. For those who want a longer commitment the one year contract plus renewal is best suited; insuring that their aquarium remains pristine and stable for years to come without having to ever worry about it themselves. A shorter term contract would be better suited for: Those who’d like to try our services before committing to anything longer, learn the maintenance process themselves only to take over their own tank in the near future, or will be away for a period of time, needing someone to look after their tank during that time span.
