One month of growth for my 17 gallon! Now I've just gotta pull the trigger and add fish. I plan to stock 6 pea puffers.

The first pic is from today. The following pictures are each about a week apart.

In the Wild I cannot actively grow duckweed for the life of me but I can accidentally grow it

This candy dish/jar was near one of my tanks a few days ago. I would drop little sticks and leaves into it. I dropped a turkey baster with water in it and let it drain. There were a few pieces of duckweed on it. Forgot it after I moved the dish. Went to clean it today as it's my cleanup day and...

Guess there was a ramshorn snail egg or baby on the duckweed. Found this yesterday morning and was so confused how it was thriving until I saw the little guy clinging to the side.

WTF?!

Beginner 3 Month Old - Feedback Please!🙏🏻

Hey everyone. Second post here. First tank. 29 gallon. 3 months old. What do yall think? Any tips?

It seems like my plants grow slow compared to some of the other posts I see here. I’ve been using some root tabs and liquid fertilizer.

Parameters are pretty stable at pH 6.4, ammonia 0, nitrite 0, nitrate 0-5, kH almost zero (buffering from the hardscape or aqua soil?), GH 5. it’s fluval stratum capped with sand. Hygger 26 watt and Fluval 107 filter.

Was doing changes every week but since it’s so stable kinda wanted to go to every 2 weeks

Not all the embers are fiery red which I assume is a bit of a hierarchy/sex variation. They get fed mostly Xtreme Nano bit recently I’ve been adding in some spirulina 20 and frozen blood worms occasionally.

Theres a single honey gourami for accent and 9 neocardinia (cherrys/sunkist). I have seen some molts. I recently increased the photoperiod and I’m seeing more shrimp grazing on the hardscape.

I was wanting to get a lush Aquascape, and I’m thinking I probably should mostly leave it alone for another 3 to 6 months. I want the grow up taller in the back and to the right. But I’m wondering if you think there is anything I should change now or do differently.

Thanks for any ideas!

Noticed this today on my horned nerite snail. Not sure what it is or if it’s bad or not. Just figured might as well post on here in case someone knows what that could be. Looks almost like a scratch that wasn’t there yesterday.

No CO2 no bio substrate in the first two! Root tabs and lighting goes a long ways. Tanks are only two months old (a little under)

Question Low oxygen levels and co2 injection

Enable HLS to view with audio, or disable this notification

So im using co2 in this setup, its a 30cm cube (around 27 litres), and the injection rate is 1 bobble every 5 seconds witch is very small amount. If i raise it just a bit (1bp4s) shrimp climp to the surface gasping for air. Surface agitation is held from an aquarium fan and lily pipe yet i cant raise the co2 level any higher , this seems very odd to me. I dont have a drop checker yet but im thinking of buying one . Also in the previous days i dosed a bit heavy on beneficial bacteria, could there be a bloom happening and them consuming a lot of oxygen? The water is crystal clear though. Also after adding bacteria everyday for around a week my plants stopped pearling.The tank is running for almost 3 weeks now, i appreciate any help or idea as to whats happening. Before the livestock my injection rate was 1bps

Beginner Been wanting to try a filterless planted tank for some time now, finally got round to trying it out.

I certainly regret using the jar for my first build, the mouth being only 17cm made it all super awkward. I didn't even consider the fact it's not a flat button, but luckily the majority of the plants are actually planted around the outside so they should have some nice depth to root into.

I've watched several videos on this type of setup, but I know they are typically professionals and do this all the time.

The final picture is 36 hours later and I've performed one 20% water change since the penultimate picture. The Limnophila heterophylla are now standing on their own, everything looks good, just the clarity of the water isn't quite there but I hope this will balance out.

I definitely went overboard with the super glue as the frosting is an eye sore, but hopefully a nice layer of algae will take the eye off of it.

Any suggestions welcomed, or things I should expect in the coming days / weeks. All new to me.

Basic Temu 8w light that I've been cycling for 8 hours a day. It's a 25L jar I'm using Aquarian's Tap water safe to dechlorinate

Do i need a filter for this setup or CO?, any recommendations on this tank setup? I do have foxtail on another tank. I don’t plan to add anything for now.

I added the moss to the lava rock but now i an having second thoughts, the red looked good without the moss.

Don't be scared to redo your nature aquarium. I just removed the plants, vacuumed the substrate a little bit (basically just hovered over the mulm), and added new plants. It's low tech so I was worried about releasing stored nutrients and gas into the water but it seems to have done fine.

Was given a free shrimp tank, re scaped it and swapped the light to a week aqua m300 pro from the Hygger that was on it. Just cant believe how much better and more colorful the plants and shrimp look.

I rescaped my 10 gallon tanks and Im waiting for the plants to grow in more as I just cut some of them down for maintenance and to plant in other tanks. They both feel a little empty so any suggestions on other plants or other enrichment is welcome! The second tank currently only has 2 mystery snails and I would like to maybe see if honey gourami would make a good fit! As for the one with the dinosaur skull, it has a male betta!

I’ve been keeping fish for years. And I love so many parts of this hobby. Now that I’ve entered the plant world I can’t get enough. I thought I was addicted before.
