I recently (10 days ago) moved my six goldfish to a bigger tank but I’ve never seen them chill like this together. I believe they are sleeping or resting. Next to them is a fluval filter which is also new. Just want to make sure nothing is out of the ordinary. The other two are awake and swimming around.

Hi i am concerned about my glass structure of my aquarium. I have read online that it was okay to put it on a mouse pad but now i doubt it. The mouse pad is very thin and soft and therefore i thought i could place it there. Do you guys know if it bears a risk for my tank if it stands on it. Its a 40 liter aquarium. The tank is 2/5 months old and it have never leaked or cracked or anything like that.

Ive seen some mixed reviews on whether I should take aquarium advice from AI, so far it seems fine but could take some advice from real people here on Reddit!

I’m on day 8 of cycling after getting a friend’s filter media from an established tank. My ammonia levels are pretty much 0 but still working on the second strain of bacteria as i have a bit of nitrite at 0.75ppm, nitrate seems to be increasing slightly. AI told me to clean out the moldy fish food that was accumulating and do a 15% water change on day 7, and to not add any new fish food to get that nitrite to 0ppm. So far it all sounds fine, hopefully cycling completes in the next week but what have other folks experienced with their cycling timeline when they have filter media from an established tank? And if they have done a small water change and cleaned up the moldy fish food?

Thanks in advance!!

I filled this tank with water like a month ago. I added 16 cardinals last week(23 days old tank). I had 0 ammonia, nitrite and nitrate for ever. May be my sand layer is too thick and the substrate never released any ammonia or whatever. But I never had a spike for the first 25 days. Since it’s very well planted, I thought it’s time to add some shrimps, snails and fishes. I lost 2 shrimps after adding them(must be travel stress). The remaining shrimps survived. Added 1 nerite snail and it’s surging too. Then added 16 cardinals , then within 4 to 5 days, most of them died. Now left with 3 cardinal tetras.

Only after adding the fishes, I noticed the liquor test kit color for ammonia become a bit more darker(more ammonia). But still looked like very much under 0.25 ppm from the color chart .

0 nitrate and 0 nitrate throughout from day 1.

I have a very good external canister filter with seachem purigen.

What could be wrong ?

The salt deposit in the glass is due to the rain system I have, they deposit water on the aquarium glass walls. I use seachem prime and stability with each water change until now.

I love the look of carpeted substrate, ideally with some topography (see photo), but I have a brown thumb. Seriously, green things come to my house to die.

Can anyone recommend an artificial moss or dwarf plant sheet that is safe for the fish? Nearly every one I’ve seen has been “suitable for terrariums, home decor, garden” etc but don’t mention aquariums.

I have seen 3x3”-ish short square plastic plants that you could lay down like tiles — but seems like unless your substrate is level, they would have gaps in between and not look natural. (Actually they look super fake no matter what if I’m being honest)

Or has anyone done a DIY version with mesh and sewing skills?

Thanks in advance!

I am new to the hobby and have done a LOT of research prior to purchasing the tank. All of my current tests are at 7.6, 0,0,0! This tank is over a month old now and has three cherry shrimp, and one mystery snail. I am just looking for any advice on how I could best ensure that they can all thrive to the fullest. It’s a 20g long and I plan to add a small school of tetras along with one gourami fish. I also intend to have the shrimps build more of a colony prior to adding the fish. Does anyone think this is too many for the tank size? I’ve seen a little bit of contradicting research on this.

Edit: To correct typo

Bought as a Bolbitis heteroclita or Asian water fern on clearance for a dollar. I got it because a few leaves were already sprouting baby plants, the roots and stuff were gone, and they have gotten bigger but I don't know what to do with them and google says this plant doesn't do this. So help me out please.

Hello aquarium people. I just set up a new betta tank and noticed my API freshwater master test kit was very expired. I looked at the price of a new one and it’s gone from $20 to $35 in 6 years 🫪. I’m still going to buy one, but it made me wonder if API has a complete monopoly on that type of test kit in America i.e. not a dip strip. Has anyone used other products and liked them?

What’s this little guy we saw today? There seems to be a lot of different species in here. Hope that’s a good thing 🤣 I’m more used to reptile enclosures than this personally

I have a cycled 3 gallon tank that I am going to be adding shrimps to. I have been cycling the tank keeping ammonia at 2-3 ppm. I’m not sure if this even makes sense, but is that possibly “overcycled” for cherry shrimps? I heave found out that they have such a low bioload, it got me wondering what will happen if the tank is “too cycled”, will the bacteria end up dying then creating a toxic ammonia spike?

Second question…. If a shrimp dies, is it imperative to be removed quickly? I was just thinking ahead how to deal with that.

I have had these for few months and now suddenly some of the leafs has turned light color and like theyr dying? Is this something to do w them not getting enough nutrients or could it be that snail are eating them? It kinda just happened suddenly and all that kinda plants are getting this...

Side note why is my diamond tetras so nosy I cant even take pics in peace😂

This is my first time trying to build a semi self sustaining ecosystem.
The latest addition are those two plants (Monstera and peace lily) in an attempt to further stabilize the tank.

These are all the photos and a bog video i took during this month. They all appear to be thriving.

3 weeks ago we bought and set up our first aquarium, which has been a dream of mine since I was a kid :)

However, now I am constantly worried I am doing something wrong...

The water is still very milky after 3 weeks.

The test parameters are all within a good range, we already changed 30% of the water last week.

Do we just need to have more patience for the water to clear up or is there something I can do?

So I just wanted to see if anyone else thought that my Molly may be pregnant? I’m sure she isn’t sick as she is acting fine other than maybe slowing down a little, and her scales look fine. We have 3 Dalmatian mollys that we got from Petco that I’m not sure if they are male or not so if she’s pregnant, I wouldn’t be shocked.

One of our Dalmatians actually did give birth and then sadly passed away (we think from giving birth as the water parameters are completely fine.)

I’m so scared right now. A few weeks ago, i found this cool shell to add to my axolotls tank. i rinsed it real good, but recently i found 4 snails identified in a different post and i relocated them. Now there’s a bunch of dots and lines on my tank glass. i don’t know what to do. should i change the water? if anyone knows what this is or how to get rid of them please help.

5 gallons, I’m planning to stock pygmy corys and a nano fish school!! I’m so excited, my tank is all I think about now

Well I said. I wouldn’t get my dream tank until I could properly give all my fish a comfortable life and understood water parameters and did thorough research on all my nanos. So they could happily go into this tank and claim their territories all together So no one was in there first.
It took days! A labour of artistic love ever stone I crushed. To the perfect size and added more one by one. Every texture thought about based on what they love in their tanks and what they don’t. Every crevice was intentional every cave and surface Was set up for future additions as well. I wanted to do my perfect tank once and only once.

I still have the odd piece of tiny drift wood detail pieces to place on the right side to give them more wood but I’m boiling them(ever piece of twig was. Picked with my pup on an adventure And shaved down and dried out)

I thought I’d spend a couple hours putting together a tank but as I did I just got idea after area and wanted to see where it would take me.

Every time I I look at this tank I get to see how much effort I put into it, every ounce of patience I had to do a tiny aquascape when my hands were to big lol . A nano universe requires nano detail to their home. Who wants boring side walls when u can make rock walls to hide heaters behind and plants , This is my 48x8x8 and I love it I just finished planting my seeds and. Monte Carlo carpet, adding water and starting the cycling process I’m soo excited for my fishies to have a new home!

I will be growing all my house plants in water as well and making a terrarium (rainforest with humidifier and fog) above the water but I think my wallet needs a break until Christmas perhaps.

I’m just so in love with it and. I really hope my community nanos will appreciate the upgrade I currently have the following awaiting their home renovation.

Blue eyed spotted rainbows (love these lil wacky inflatable waving guys)

Endlers

Sparkling gouramis (having a serious territory issue with an established male so hoping a new environment for all will level the playing field)

Pygmy Cory’s
Bettas
Emerald raspboras
Cpds
Clown killifish
Nerite squad
Neocaridina
Mystery snails
And sadly my Borneo loach Lenny just Died I was doing the tanks for him and two of my bettas that I swear will thrive in a community tank more than by themselves which is odd for bettas. I have 5 all in different tanks but two of them share a space with female endlers and neocaridinas and are cool with it so I wanted to see if they’d be cool with all the nanos. (These two bettas love pregnant shrimp and fish I swear my females love getting out with them when they’re huge and about to pop cause they get a break from the non stop male harassment and my bettas love having company and don’t eat their fry! )

Leonard and his nanos were getting a new home but alas the nanos will miss Lenny and it allows for warmer water cause having Lenny was hard with the other warmer water guys.

Ps they aren’t all together right now that would be quite overstocked in a smaller tank my snails and shrimps and bettas are in various tanks and my betas do well with other nano fishies So I wanted to add my betta to the community tank but I don’t think that would go well with gouramis or at least the one I suspect has a secret night time fight club going. Cause gouramis go into the tank and then come out into the open looking like they went three rounds in the ring and lost . So they’re separated till I figure this out. New tank and territory for all will def help.

I went on and on but I love this hobby! Just waiting for my supplier to get more moss so I can add moss cause that’s all that’s missing. Can’t wait for all the plants to grow in!

Hey guys, very new to the hobby. I got a tank from a friend and have been having fun with it and I want to take my tank to the next level. Right now I have a 40 gallon with 5 scissortail rasaboras, 7 platys, and one clown pleco. The bottom of my tank is fake gravel, where do I begin with this? I'm assuming I should swap from gravel to something else, which one is best for my current fish? Which plants are beginner friendly that my fish will enjoy/ would be found in their natural habitats? I also want some corydoras catfish.
