I have a 6G Fluval Edge lightly planted community tank (2 guppy, 4 ember tetras, ~50 cherry shrimp, 2 nerite snails. Established for about 6 months. I noticed some of my plants were wilting and some were really thriving so I added a small dose of Seachem Flourish aquatic fertilizer. About an hour later all these small white worms were crawling all over the glass of my tank. They appear to be white and tube shaped. What might these be? Is this a sign the fertilizer is causing problems within my tank? My ember tetras have also been hiding in the plants pretty much all week and not coming out. Ideas on what these worms are and what might be going wrong in my tank?

The tank is 18”x6”x6”. It has no heater, but has a small pump embedded into the land area, drawing water from the gravel into the open water on the right. The water is cloudy because I just set it up yesterday.

In a month or two, what fish could inhabit this tank? I’d love celestial pearl danios or habrosus corydoras, but I’m afraid the tank is too small. Anyone have experience with fish in pico aquariums?

Is there any species of fish similar to a bichir or eel that can fit in a 30-gallon long tank (other than kuhli loaches)?

to keep it short and sweet my sister 21f and i 17f that’s not important what is is she bought this a while ago and is forcing me to turn this cup into an aquarium can this be a wasteland shrimp tank yes or no i told her it can’t be a betta or a goldfish ffs 😀it’s WAY too small like the picture makes it look huge yes that’s a mint container above it i’ll try to take measurements to see if it even takes a liter of liquid she knows nothing about aquariums therefore she’s NOT going to take care of it because in her mind it’s just fish+water=fine she has a leopard gecko and for her that’s plenty so i’ll take care of it and i’m willing for a challenge but just tell me could this possibly work at all ? with like two shrimp even just one????

I haven’t added my snails yet since I just got the tank today. Definitely planning on adding more aquatic plants!

Hello! My fiancée recently got me a small 5 gallon tank that was supposed to be for Glofish and I got a shark , one barb , one pristella and I had 2 tetras but they died . I have recently noticed that the shark is quite aggressive , I see it chase the pristella around and I think it’s intimidating the smaller fish because the smaller fish are only staying on one side . I’m planning on returning the shark but I don’t know how to organize my tank , I was thinking of getting some shrimp or snails but I don’t know how compatible they are with these fish , I could use the help on how to fix this problem, before these fish I bought 3 female betta , one tetra and one corydora catfish but only 2 betta survived, I am not sure what I am doing wrong so pls help !!

I wanted too do a 1 gallon shrimp tank with just 2 rimsim, maybe a bit bigger, I was going too put a moss ball and a few more plants + food of course on a feeding cycle, could it work? This is a rough mock-up but It isn't the best, open too advice!

Hi dear community,

I am seeking your advice and wisdom.

After careful consideration, I am moving closer to purchasing a Nano Cube (Dennerle 30l / ~8Gal), which I intend to stock with a male Betta (and perhaps some snails and shrimp).
My goal is to keep the bio-load as low as possible, because i would love to add the fish 1-2 days after setting up the tank.
I am fully aware, that cycling without any stock is recommended, but i am also aware, that starting a new tank with 1 fish is possible, if done correctly - which leads me to my inquiry:
Would you be so kind as to share a "battle-plan", suggest a few add-ins like beneficial bacteria and a rough water-change schedule?

Side note: I have a 3gal planted filterless tank, which is somewhat seasoned and currently only hosts snails. Water tests are coming back very healthy. Would it help the new tank, to add some water from the planted tank, to get in some of that beneficial bacteria? The betta-tank will have a filter.

Pics of said 3gal tank added, so the post is a bit nicer to look at :)

Any input, recommendations and sharing of experience is highly welcome and appreciated.

Hey everyone.

Had a 200 gal paludarium before paludarium was a word. But that was a long time ago and the size made it almost idiot proof.

Excited to get into nano planted tanks. Considering an Iwagumi style with Blue Mountain Seiryu rock and Christmas Moss. Figure I'll go DSM.

Navigating all the info out there has been overwhelming. If you were me, how would you go about things? A different ground cover like Pearl moss or Monte Carlo?

Appreciate any straightforward advice you can spare

4 gal, UNS 25C, low tech

Also if you know how to get rid of it and keep it out that would be great

I’ve come across almost every single problem with getting my first tank set up. I’m on day 7 of fishless cycling so it’s getting close to when I might be able to add fish. I want to have 2 clowns, a cardinal, yellow watchmen and maybe a fire shrimp. My question is the order of adding the fish. I’ve heard that you should start with clowns to help cycle but also they get aggressive. So should they go in last or first? Should I get the 4 all at the same time so they can pick their spots and not have to fight about it later?

This is a 32 gallon biocube

It's approximately 20 litters of water

I recently purchased a 5.5 gallon as a backup in case my live plants decide to propagate like crazy, but was wondering if I could stock anything once it's properly cycled. I've come up with some ideas, which are as follows:

1) Plants & Neos (maybe fish?) - I love the colors of Neocaridina sp., and I'm considering some of the blue ones to contrast a Scarlet Badis, or some of the red/red stripey guys to compliment the yellows of a Licorice Gourami. Feel free to make more fish/shrimp suggestions as well.

2) Betta Biotope - planted blackwater with driftwood, catappa, etc. Thinking about a female halfmoon, male samurai, or potentially a wild-type smaragdina, imbellis, antuta, something like that. Please let me know if a 5.5 is considered too small for bettas.

3) Crabs? - since the tank is just a standard open-top, I was thinking of doing a mini paludarium and stocking some small crabs in it. I was thinking Halloween crabs, but they're probably too big, and I don't think they're terrestrial either. Let me know if there's any species you have in mind though.

Thanks in advance!
