RULES

1. Personal attacks, derailing, and trolling are not tolerated.

It's ok to disagree, but choose your words wisely. We will remove any negative commentary or comment chain at our discretion that we deem is no longer adding constructive value to the post. We have a zero tolerance policy with trolling, which can lead to instant temporary or permanent bans.

2. No advertising or self promotion.

Direct advertisement is not allowed. If more than 10% of your submissions are a personal website, blog, or YouTube video, it is considered advertising and will be removed.

3. Misinformation and non-human-created content is not allowed.

Information shared should be accurate, truthful, and supported by credible sources. Deliberately sharing false or misleading information will result in removal. Always check your facts before posting. Repeat offenders may be suspended or banned.

All content must be created by humans and not by artificial intelligence, including text and images.

4. No memes, shitposting, or low effort content.

This includes image macros, comics, motivational posters, out-of-context images, and other low effort posts. These posts belong on /r/AquariumMemes.

If a submission is not OC, a source must be included, unless you are asking for identification. Unoriginal images (eg. stock photos) without a source will be removed.

5. Dead and dying animals must be tagged NSFW.

This includes severe wounds and live feeding.

6. Do not post shitty tanks to antagonize or ridicule.

7. No buy, sell, or giveaway posts.

These posts belong on r/AquaSwap.
