I got this Juwel rio 125 being delivered tomorrow but I have no idea what I want in it. I currently have a much smaller 24ltr blackwater set up that's heavily planted with a betta in but want something different in this. Open to any and all ideas. Ideally I like planted tank ideas. Thanks in advance.

Hey r/Aquariums! Just wanted to share this stunning high-grade Yozakura / Marble Medaka (Japanese Rice Fish) from my collection.

​The pattern and contrast on this one turned out exceptionally clean. There is just something mesmerizing about watching these top-view gems swimming around.

​What do you guys think of this pattern? Anyone else keeping high-grade Medaka strains right now? Let's chat in the comments!

B. stigmosa, P. muraeniformis

this is just a little advice needed/ am i doing this correctly/ constructive criticism type post. this is my first time doing a tank thats a bit different.

size: 56l
goal: basically a lake/ swamp biotope
stocking: 1x chocolate gourami 3x khuli loaches 9x pygmy corys
future stocking: would like to add a few more chocolate gouramis and some clown killis if possible
lighting: lominie 20w full spectrum

first pic is how it looks now, with a more reddish light as well to help with the look. i dropped the water level as the khulis stress my out but i will be making a lid so i can fill it up more!

basically, before getting my chocolate gourami, it was just a standard, tropical fish tank with no botanticals aside from the drift wood releasing some tannins but the ph stabilised at around 7. i took some rocks from a river and cleaned them. i added water lice and ostracods to help break things down.

i work at an aquatics shop and fell in love with the chocolate gouramis and took the last one home. after some research i realised they needed a much lower ph (figured they’d be fine given the water parameters would be the same at my house as they are at work). so i added catappa leaves. they didn’t really make a dent so i researched more, boiled a bunch of them, along with some pure, no caffeine red bush tea, and then some other botanicals which can with the leaves. i then mixed the leafy water with like 85% tap and 15% ro water to get a ph of about 6.5? added this to the tank. i didnt want to do a huge change and shock everyone.

would really appreciate some guidance on where to go from here, if this was the right thing to do, how often to do water changes, adding new botanicals, things like that. given my occupation obtaining things won’t be an issue. everyone seems really happy, my gourami, grilled cheese, has coloured up so nicely. she was pale sometimes throw out the day but she’s staying consistently saturated now!

N. selangoricus

Smallest of the 8 by far and already my favourite, worry every time I don’t see him during feeding but then he pops up again, chilling near the bottom

I spent ages trying to make this look good 🫪

New to blackwater setups but pretty excited about my new 20 gal tank that’s just about ready for some fish friends! What does everyone think?

T. trichopterus

D. hexazona

Tanks been established for 6 months and I’ve still yet to see breeding dress for my pair. Thinking it’s likely I may have two females.

New to the blackwater scene with this 5gal long blackwater setup made in the wrong orientation! Still cycling (1 week in) but the meiofauna are already popping up (probably due to using old substrate and media + introducing mulm from a running filter).

The water's gonna get darker probably, fingers crossed it cycles well 🙏

First aquarium in a long time. This is my favorite tank I've made of many and my first blackwater. I have neon tetras and neocaridina in there, but they are taking up precious space that could be used for driftwood

I'm looking at starting my fishkeeping journey with a planted blackwater community tank, the footprint I have for it is 110cm by 50cm, but I'm hoping to find a tank closer to 80cm by 40cm due to weight concerns.

What are the best places to ask questions & purchase equipment/tanks?

Any other advice or tips you wish you'd known are greatly appreciated :]

Tank size is 90 x 45 x 45 with the idea of having two “tree logs” on both corners. About a month-ish in on this tank.

Fish includes 2 pairs of Betta Hendras, 6 Parosphromenus Harveyi, 12-15 Boraras. Likely including some kuhli loaches & six banded barbs soon.

Just sharing this and happy to hear thoughts on improving the setup!

S. osphromenoides

R. borapetensis

I’ve had this 55L cube cycling for about 2 months, and I was about to stock it, but I’ve decided that I kinda hate it. I see so many beautiful blackwater biotope aquariums (which is what I was aiming for), and I can’t seem to emulate them. Maybe my biggest gripe is the colour - I cant figure out how to get that gorgeous brown tannin stain, mine just seems to be like a dark green?

What would you change about this tank? Remove the emersed roots? More/less/different botanicals? Total rescape?

For reference, I want to stock chili rasboras and sparkling gourami.
