A Reminder About How We Treat Other Members

124 Upvotes

Hey everyone,

The mod team has been seeing an increase in comments that are unnecessarily rude, hostile, condescending, or outright mean toward people asking questions or sharing their aquariums.

We recognize that this has become an issue. We have also received modmail from members bringing these concerns to our attention, and we appreciate people letting us know when something is happening that we may not have seen.

That said, there is an important limitation that we want to make clear: we cannot monitor every single post and every single comment.

Moderating r/aquarium is a volunteer responsibility. The moderators have jobs, families, school, personal responsibilities, and lives outside of Reddit. We do our best to keep up with the community, but it is simply not possible for a small mod team to read every comment on every post every day.

This is where reports are extremely important.

If you see a comment that violates the subreddit rules, please report it rather than engaging with it or allowing the situation to escalate. A report brings it to the mod queue so that we can review it and take appropriate action.

Changes are coming

We will be adding and clarifying rules regarding how members interact with one another. Going forward, comments that are unnecessarily hostile, insulting, mocking, belittling, or otherwise violate our rules regarding respectful behavior will be removed and bans will be enforced when appropriate.

We also want to be clear that "I was just trying to help" does not excuse being unnecessarily rude. Aquarium advice can absolutely include criticism, disagreement, or pointing out mistakes. You can correct someone without attacking the person asking the question.

Depending on the severity of the behavior, previous moderation history, and whether the behavior continues or escalates, bans may range from:

• 1 day

• 3 days

• 7 days

• 14 days

• Permanent

Repeated rule-breaking will result in increasingly serious consequences.

Additionally, repeatedly making multiple comments on the same post that violate our rules may result in further action, even if each individual comment might seem relatively minor on its own.

Remember who you're talking to

r/aquarium is a community with people of many different ages and experience levels. Minors may also visit, post, and participate in this subreddit.

Please keep that in mind when interacting with other members. Regardless of someone's age, experience, knowledge, or mistakes, they should not be subjected to harassment, sexual or inappropriate remarks, personal attacks, or other behavior that would make this community an unsafe or hostile place to participate.

You do not necessarily know who is on the other side of the screen, so think about what you're saying before commenting.

Many people come to r/aquarium because they are looking for help. Some are beginners who genuinely don't know something yet. Others may have made a mistake and are trying to correct it. Being told what they did wrong is useful, however they also need to be told how to correct it. Being mocked, insulted, or made to feel unwelcome is not useful or helpful.

You do not have to agree with someone to treat them with basic respect.

So please remember:

If you can give constructive advice, give it.

If you can disagree respectfully, disagree.

If you can't do either, don't comment.

Want to help the community?

Our moderator applications are currently open and are pinned in the highlighted posts at the top of the subreddit.

As the community continues to grow, we could definitely use some additional help from knowledgeable and active members of the aquarium community. If you have experience with aquariums, enjoy helping others, and are interested in contributing to the community in a positive way, we encourage you to apply.

Being knowledgeable about the hobby is important, but so is being able to communicate that knowledge respectfully and constructively.

The mod team will be addressing these issues more consistently going forward. We also ask the community to help us by reporting rule-breaking comments instead of contributing to the problem.

Thank you to everyone who helps make r/aquarium a welcoming place for aquarium keepers of all experience levels.

Announcing our new community icon! (and an update from the mod team)

30 Upvotes

Hey everyone,

We heard your feedback loud and clear regarding the recent icon change. The goal is always to keep r/aquarium a vibrant, welcoming space that reflects the incredible passion of our hobbyists, and it’s clear the community prefers authentic, human-made artwork to represent us.

An incredibly talented artist in our community, u/SuicidalFlame (Check out their tumblr too! https://firenagy.tumblr.com), generously stepped up and designed a brand-new, custom icon for the subreddit! We are absolutely thrilled to debut their work today. Please join us in giving them a massive thank you in the comments below for dedicating their time and talent to leveling up our community's look!

A Quick Note on Community Boundaries

While we always welcome constructive feedback and open discussion about the state of the subreddit, the mod team has a zero-tolerance policy for harassment.

Lately, targeted mass-reporting and personal harassment have been directed at our moderators. We want to be entirely transparent: if you are unhappy with the management of this subreddit or feel the need to harass the people who volunteer to keep it running, you are more than welcome to leave.

Healthy debate is fine; stalking, toxicity, and abusing the report button are not. Future instances of targeted harassment will result in an immediate permanent ban from the community and will be escalated directly to Reddit Admin for violating the site-wide Content Policy against harassment.

Thank you to the 99% of you who make this a wonderful, supportive place to share our tanks every single day. Enjoy the beautiful new look!

I have a tank with just one male betta and one mystery snail in it. I found these little black eggs floating on one of the plants I have in the tank. They were at the surface of the water I’m sure they’re eggs because they felt really slimy and were all stuck together when I touched them. I know it’s really hard to tell but does anyone know what these eggs are?

Help Transition to Planted?

Post image
Upvotes

Hi everyone!

Now that I have had more experience and research on fish keeping, I really want to transition my freshwater tank from artificial to planted.

Currently, my 10gal is only home to my beautiful koi betta Mina.

I am trying to give her the best life ever which is also why I want to transition to planted and dull the colors out some as well.

Any advice? Would the easiest solution be to save up for a new tank and lay substrate down first? I have extra sand already. Or should I remove the sand enough to lay substrate? Or can the substrate go above the sand?

Any tips or thoughts or suggestions (as well as some starter plants for a beginner tank!) would be so helpful <3

Attached is a pic of Mina in her current tank!

Discussion Looking for ideas

I want to make our aquarium a bit nicer looking. We upgraded from a 6 gallon to this about 6 months ago and budget didn’t allow me to buy much for it. I’m thinking maybe a bigger driftwood? I do not want to pull the tank apart as we have an established shrimp colony and guppies. It needs to be things I can do with the existing fish and shrimp remaining in there.

Any ideas? Thanks!

Discussion Chloramine Testing

Upvotes

My local tap water provider uses chloramine. I've searched low and high, and I haven't been able to find a test kit that would actually test for chloramine.

There seem to be plenty of tests for free chlorine which apparently wouldn't show chloramine presence only chlorine, so a total chlorine test would be needed. Is there really no such thing (total chlorine / chloramine test) for aquariums?

Help Algae and acidity issues

Post image
1 Upvotes

Hi everyone! I’ve been fish-keeping for about a year and a half but over the last year or so I’ve been having a bad acidity and algae problem… my aquarium is far too acidic and I can’t figure out why. I don’t understand why but the algae has been changing in colors (from green to brown and vice versa) and it just keeps growing. I want my fish to have the happiest life possible and I know that with these conditions it’s not possible. Can someone please help me understand what is going on and how to fix it?

P.S. the picture attached is what the tank looks like directly after cleaning. It’s a 20 gallon tall tank holding 6 Cory’s, 1 Long Red-Ginned tetra, 1 Guppy, 1 Pleco, 1 Octo, 2 Neon Tetras, 5 baby Tetras (I’m not completely sure which ones, I believe they’re a mix of long red finned and black skirt), and 1 African Dwarf Frog. Please let me know if you need any additional information!
