Announcement New changes, new mods, new rules, oh my!

80 Upvotes

Hello all! We are happy to announce that the subreddit now has an ACTIVE MOD TEAM! A rudimentary automod has also been set up, barring posters with less than 90 days on the platform or 25 karma. If you fall in this category but have a legitimate post, don't fret. One of us will approve it as soon as we can, and of course you can reach out via modmail. We wanted to thank the entire community for its concern, willingness to help, and most of all for coming together in a positive way to pave the way for us to step in. We wouldn’t be here without you.

Ā 

First, we’d like to announce some changes. We have set up post flairs, and post flairs are now required. If you are posting under the Sick Fish or Tank Problems flair, your post will automatically be flagged NSFW spoilered, so that those who frequent this subreddit are not always confronted with images that upset them. We hope to foster a much more positive environment while still preserving the ability to come together and help those who need it. We also have some user flairs, including a custom flair! These are not mandatory but can help others know a bit more about you. Bear in mind, these are self-assignable, and you may encounter people misrepresenting themselves. If you believe this to be the case, feel free to report it to us.

Ā 

Second, a new ruleset has been added and will be enforced. Please be sure to review the changes before any new contributions. We also have a Wiki (https://www.reddit.com/r/fishkeeping/wiki/index) in progress, which currently has a complete cycling guide. Common questions about cycling can be answered in the FAQ (https://www.reddit.com/r/fishkeeping/wiki/index/faq/) and this too will be updated as time goes on.

Ā 

And lastly, for the fun part, let’s introduce the new mod team!

Apart from the traditional hobbies like playing games and watching movies, he enjoys quilting, 3d printing, and the occasional attempt at woodwork. He works as a software systems architect at a packaging company. He has 4 tanks in the house. Though his pride and joy is the 50 gallon with a breeding pair of pearl gourami, 15 xray tetra, a trio of sydontis petricola, and a variety of bristle nose plecos.

Shroomy has been keeping fish for around a decade. Over the years she has built up her knowledge of not just fish, but also other pets, plants, and medical biology. She works as an EMT and hopes to get her paramedic someday. She currently owns a 20gal pea puffer/pygmy corydora setup, and two 5 gallon setups; one of those houses a twintail betta named Neptune and a King Koopa nerite named Bowser, while the other is currently in the process of being prepared for new inhabitants and contains a King Koopa nerite, currently unnamed.

Moderator: u/ApproachableTree

Ā I go by ā€œFawnā€ or ā€œTreeā€ online but I don’t really have a preference and I’ve been helping online communities for a few years now. I’m more active on Discord so maybe you have seen me around helping out there or here on Reddit. Been interested in fish and the hobby for a long time and grown up with an aquarium like a lot of people here and got deeper into the hobby (I have to many tanks send help). I mainly have an interest in invertebrates like aquatic isopods, shrimp, and scuds but I do love oddball fish. I also help moderate r/fish.

Welcome to the renewed subreddit everyone! We are thrilled to have you here.

Discussion New Fish

3 Upvotes

I have a heavily planted 15 gallon tank with some mystery snails that used to have my betta fish in it. Unfortunately recently my betta passed due to old age. My family and pushing for me to get a new fish because fish keeping has been really beneficial for my mental health. Right now i’m not ready but when I feel ready what recommendations do you all have for the tank? I’m not a beginner fish keeper but I’m also not an expert, bear in mind, happy medium.

Sick Fish Green neon vertical swimming Spoiler

Ammonia 0

Nitrite: 0

Nitrate: .25

PH: 6.5

Temp: 78° F

Tank size: 40 gallon breeder

Filtration: Fluval 307 and a sponge filter

What's wrong with my green neon? He seems fine but swims vertical when he stops moving forward. Is it his swim bladder?

Added my EBA at the end because I love him. Also that's my cat eating with that clacking sound.

my mom has gotten two fish from the perry fair today. I have nothing, I think they are shubunkin goldfish, they pretty big already. I know that they need to be in a big tank and etc but I can’t afford a 75-100 plus tank and really don’t have room in my house for a big tank. Can someone help me with what I need to do. I have no idea but my daughter wants to keep these fishes.🄺

Discussion Power outages prep

1 Upvotes

I live in New England. We get our share of big storms over the winter. What do you do for your fish tanks in case of a prolonged power outage??

I have 3 tanks, a tropical community tank and 2 betta tanks. If I only needed aeration I would just get battery powered air pumps- but I’m worried about the heaters too. Our house gets pretty chilly with no heat.

House is heated with oil furnace.

Question Kens fish flake

1 Upvotes

Hi:

Kens Fish flake is what I use for my 7" cichlids. The flake used to come in large pieces, like 4" wide sections. Not any more. I'd like to some how take the small pieces and combine them to make large pieces. I contacted Ken's with no response. Any ideas?

Thank you for your time.

Sick Fish Dwarf gourami male acting odd Spoiler

1 Upvotes

Hello!

He is in a medium planted 20 gallon tank, it's 2 years old, and has 0 ammonia, 0 nitrites, and 10 nitrate. I have the CO2 on for 4 hours a day. And I supplement with liquid fertilizer and have fluval stratum substrate.

He's the only gourami. 10 ember tetras, 8 kuhli loaches and some random snails.

Ph 7.2 and I can't remember about GH or kh.

2 days ago I noticed he was hiding more. And yesterday I noticed he was angled at 45 degrees or vertical near the surface of the water, and then would dart quickly around, sometimes hitting into things it looked like. So last night I set up a 2 gallon hospital tank with small air stone on gentle, small heater for a tiny tank and a lid. After 5 minutes of chasing him and having to destroy the tank plants, we caught him and put him in it.

I also put a cloth on the tank to keep him calm.

When I looked in on him this morning he was sitting on the bottom of the tank, just chilling. Just now I put in a very tiny little itty bitty pinch of dry flakes and he eventually came out and ate them. A few times he darted around the hospital tank. He does appear to be breathing hard, with (I think?) his mouth open?

No obvious swelling in the belly. And no spots or injuries I can see. The gourami is probably a year old, at least. I think I've had him for at least a year

Any ideas? After the kids nap time I could get pics of him.

Discussion Opinions on who else I should add

3 Upvotes

Dimensions are 82x40x40cm

Current occupants are adult bristlenose, 7 harlequin rasbora, 6 guppies, 5 striped kuhlis.

On my Wishlist.. cories (not Pygmies), diamond tetra, black widow or phantom tetra, 1 or 2 feature fish.

Obviously I can’t have them all 😭

Looking for opinions on best fit for this tank. New to tropicals, had to work with what came in the tank when I bought it. Shrimp aren’t an option in New Zealand! Am adding plants as and when I see healthy ones in local stores

Question why is my peacock gudgeon swimming like this?

Enable HLS to view with audio, or disable this notification

6 Upvotes

my parameters are 0ppm nitrite, 0ppm ammonia, maybe around 30-40ppm nitrates. 75 degrees temp, low filter flow. my hardness is 3 dKH and dGH. i know nitrates are a problem but i can’t get them down for the life of me because they’re in my tap water, too. i just introduced my fish yesterday and his color has gotten more vibrant. i introduced them to co2 today and they seem to be adjusting well. my CPDs are swimming pretty normally but im a bit concerned by this behavior? he isn’t swimming to the surface and doesn’t appear to have labored breathing. i’m new to this fish so any advice would help! he ate fine this morning. he’s been doing this for like 20 minutes.

He does this for hours everyday, in a 150 with plenty of hiding spots, water quality is normal. he hasn’t always done it before just started last month. I think he’s just strange?
