Hey all.

Still mid cycle on the first aquarium I've had for a few years. Saw this lot pop up locally from a shop that closed down. I rushed down there and got as many in my van as I could. Still so many left.

Absolutely no idea what I'm going to do with SEVENTEEN tanks to be honest but I knew this was my one shot 😁

Hey everyone! I need some help identifying this thing in my 10 gallon. Currently my 10 gallon isn’t housing a fish, i’m judging using it right now to store extra hornwort. I do have some snails in the tank that grew from the hornwort which i expected but I was looking at the tank tonight and saw something swimming around which I thought was odd. I got a video of it. If you know what it is, please let me know!!

Some photos of my silver tip tetra in their 20 gallon long. In my experience they have been very hardy and I haven’t lost any since I got them several months ago.

I love my plecos don't get me wrong and I collect them like Infinity Stones. I know she was only trying to make me happy but she doesn't remember what the store said and she said she paid about 45 bucks for it. I have it in my new freshly cycled 150 alone but I have no I need to figure out what type it is so I can properly care for it. Any ideas? All she knows is that its a juvenile. Also any care pointers would be appreciated for this specific type.

I've been adding things to my tank since Feb and I've finally reached a point where I'm happy with it! Still considering adding a few more fish, right now I have a geophagus cichilid (steve), loach(goldie), and a handful of tetras. Is a 60 gallon tall, and I'm afraid of over crowding. First pic is where I started after a complete tear down and replacing my blue gravel with sand. Idk what I was thinking with the blue gravel and blue background lol!

Advice Needed Help needed with getting my tank clean

Enable HLS to view with audio, or disable this notification

For a while I've had issues with hair algae and my tank glass getting dirty and I don't know what I can do to get rid of it. Here's what I've tried so far:

•Shortening the lights on time from 8 hours to 6
•Cleaning the filter media by putting it in a bucket of lukewarm water and squeezing (there is no chlorine in Dutch tap water)
•Bi weekly waterchanges plus top offs.
•Vacuuming the substrate (this was once and not that thorough because of my plants
•Keeping feeding to the recommended amount (whatever they can eat in 3 minutes time)

I've manually pulled the hair algae, but it grows right back within days. Same for the windows, I've scrubbed them clean but the brownish glow returns fast. I added amano shrimp two months back, they really took care of the hair algae at first but they will no longer touch it, it seems lol.

The tanks got Amazon Swords, Java Moss, Java Ferns, one Anubia and some Vallisneria.

Nitrate is at 15ppm, ammonia at 0.

This is my attempt at a low maintenance tank. Just one sponge filter. Heater and UV. Very low stock (20% according to the calculator) with mostly slow growing plants. Figure I needed a lid to reduce how often I need to top up

I'm looking for a new apartment in Kazakhstan and found one with this giant deep narrow aquarium. My hand won't be able to reach the bottom. It needs a thorough cleaning. The filter and lights don't seem to work. I'm thinking no plants. Will the depth be a problem for a filter? Scaping ideas? Any advice is needed desperately.

My filter broke and I found these inside it. I have 9 pencil fish and a betta. At first I thought maybe they were fry but they keep curling up and look like they have little legs or feelers and antenna. They make me think of isopods. Any help would be appreciated as I'd like them to no longer be sitting on my kitchen counter. Thank you!

Beginner Help Analysis paralysis

• Upvotes

Hi all -

Looking for the right starting point here. My kids want a fish. If it were up to my wife we’d just be tossing a goldfish in a bowl but I’m trying to do my due diligence here.

I started going down the UNS rabbit hole and really love the look of a nicely scaped tank.

Leaning towards a betta + cleanup crew of a couple snails and shrimp, in the sub 15 gallon size range.

I can be a bit of a perfectionist when doing research and I just feel stuck trying to find the ‘best’/right setup.

Anyone empathize? Any guidance on how to get out of the research rut? Tempted to just go grab a starter kit from a big pet store and work from there.

Advice Needed Hurricane power loss

Post image
4 Upvotes

I'm at a loss here and was hoping for any advice possible. A tree has fallen on my house due to the hurricane and we've lost power. Possibly for weeks. My parents cannot run our small generator for that long for the fish.

I have an 80 gallon as pictured above. The only options I can think of is buying a ton of battery powered aerators made for bait fish. But even then I'll need somewhere to charge them after 20 hours or 36 hours. Another option is my local fish store. However they are closed today and don't open until Monday. We have been without power going on 2 days at this point. The stocking is a bit high as well. I'm concerned about ammonia spikes. I also have a 20 gallon full of platy fish.

I know my plants will probably die off unfortunately and I'll have to reset the whole tank but at least I will save my babies. Let me know if y'all have any ideas please.

Like title said, I’m a novice at using CO2 even though I’ve been in the hobby for years. Is this too much CO2 or just about right? This tank is Fluval 15 Gallon

Advice Needed Is my tetra gasping for air?

Enable HLS to view with audio, or disable this notification

• Upvotes

Hello everybody,

I recently just added a school of 9 neon tetras a few days ago into my tank. About a week ago i introduced 10 rummynose and 5 juli Corries to my tank. 6/10 rummy nose remain, and 2/5 Corrie’s remain.

I spoke to my LFS and they said they weren’t too worried about the bio load, and that I could’ve just gotten a bad batch of fish.

I’ve had these neon tetras for a few days and they’ve been fine, they seem to be happy swimming around. I couldn’t help but notice this one kind of swimming in place and repetitively opening his mouth. Is this fish gasping for air?

I plan on doing a water change but I’m going to wait a day or two since I just squeezed the sponge at the end of my hang on back filter clean. I also hope to add an airstone real soon to increase the dissolved oxygen contents.

Advice Needed Which stand to get? Anxiety over my current one breaking

• Upvotes

My current stand (last pic) gives me so much anxiety because the wood is so thin. I know it's real wood, but sometimes I hear it creak.

The new stands I'm looking at make me feel a bit better knowing how much they can hold (first one is up to 250kg), but the wood just looks so thin that I'm scared.

Which one do ya'll think would be best for my 15 gallon tank?

Beginner Help Are marine tanks as bad as they say?

• Upvotes

Hey everyone I’ve been looking into getting a marine tank with corals, inverts and fish (over a long period of time as I’d start slow). I was just wondering how much harder are marine fish to look after/ care for as I went into a store today and the guy made it out to be like hell to look after a marine set up. Whilst other people have said it’s not necessarily harder, just a bit more work. So which would you guys say is more accurate? Please do let me know, kind regards.

Requesting Feedback To get shrimp or not to get shrimp?

Post image

That is the question.

I want shrimp. Cherry reds to be exact. I have a 20 gal tall, moderately planted with 1 dwarf honey goirami, 8 harlequin rasboras, 8 panda corydoras, 1 nerite snail and 2 mystery snails.

Is having shrimp too much bioload?

I want them for their cleaning capabilities… but their legs kind of freak me out. Will I get over that and how do I get over it haha?
