Terms of use

Aquarium Architect is a free aquarium compatibility planning tool. It uses curated species data and a rule-based engine to flag potential issues with a hypothetical tank stocking. It is not a substitute for advice from a veterinarian, an experienced aquarist who can see your setup, or the dealer you're buying from.

The species data was pieced together from FishBase, SeriouslyFish, manufacturer specs, and long-running reefer consensus. Some of it will be wrong. Some of the rules will miss edge cases. Use the feedback page to flag corrections. The site is provided as-is, without warranty. If a stocking suggestion ends in dead fish or angry tankmates, that's on you to verify against multiple sources before spending money.

• Don't scrape the species data programmatically. Hit the feedback page if you want a copy for legitimate use.
• Don't submit fake partner-store applications, fake feedback, or otherwise abuse the forms. Either gets your account closed without notice.
• Don't try to break in. Bug reports and responsibly disclosed security issues are welcome at the feedback page or directly to lr103724@gmail.com.

Accounts are free. The site uses them for cloud-syncing your tanks between devices and for routing partner-store applications. I can suspend or remove an account that violates the acceptable-use section above.

Minimum age 13. By creating an account you confirm you're at least 13 years old. The site isn't built for children under 13 and doesn't knowingly collect their data; accounts found to belong to under-13 users will be removed.

If you publish a tank to the community feed or post a comment, you keep ownership of what you wrote — you just grant Aquarium Architect a non-exclusive, royalty-free licence to display it on the site so other visitors can read it. You can revoke that licence by deleting your post or your account.

Don't post anything that infringes someone else's copyright, doxes anyone, threatens or harasses, advertises commercial services, or otherwise breaks applicable law. We can remove content that violates this without notice.

If you believe content posted on Aquarium Architect infringes your copyright, email lr103724@gmail.com with: a description of the work, the URL of the allegedly infringing content, your contact info, a statement under penalty of perjury that you have a good-faith belief the use is unauthorised, and a signature. We'll act on valid notices and notify the poster, who may file a counter-notice.

The Stock Up panel may link to retailers (Amazon, Chewy, others). If any of those links are affiliate-coded, the operator may earn a small commission at no extra cost to you. We disclose this here rather than in tiny grey text under every link, but the affiliation does not influence which species or products get flagged as compatible by the engine — the rules in the compatibility engine are written without reference to any retailer's catalogue.

This is a hobby project, not a business. To the maximum extent permitted by law, the site is provided without warranty and the maintainer isn't liable for any loss (financial, livestock, emotional, or otherwise) resulting from acting on what the engine says. Always cross-reference important purchases.

These terms may change. Meaningful changes get reflected here with an updated date below. If you keep using the site after a change, you're accepting it.
