Here is my 20-gallon long community tank. Set up: Around 2 years ago now.
Stocking includes:
8x Harlequin Rasboras
6 Peppered Corydoras
15 Ghost Shrimp (all of them are in my 5g for quarantine, during a treatment, for anchor worms which was completed and was successful, they will be moved back soon!)
2 Nerite Snails
Countless Ramshorn snails
Will get more Corydoras soon.
Parameters are 0 ammonia, 0 nitrite, 25 nitrate, 7.5 ph. It is a very stable and healthy tank.
I use the GLA PPS pro method for dosing Macros and Micros. 1.5 ml Macros, per day, 0.65 ml micros. I do a weekly 50% water change with double dose Macros no double dose micros after the change. My light is a hygger, I have the specific name somewhere, but it slips my mind. It is set to 10 hours on around 40% brightness. I have two ACO sponge filters in there, on either side, hidden well by my sword and bulb plants. I feed my rasboras a mix of flakes, frozen, freeze dried, pellets, once per day. And some algae wakers, and/or sinking carnivore pellets for my corys, and algae wafers for the shrimp.
Plants are:
Ludwigia natans super red
Helanthium bolivianum Quadrocostatus
Limnophila rugosa
Limnophila aromatica mini
Limnophila wilsonii
Amazon Sword
Lilly bulb
anubias nana

My 90L (23gal) set up late Oct 2025. Stocking is 6x Sawbwa resplendens (1M / 5F), 3x Annamia-normani, and 5x amano shrimp. The last few months has seen this tank lose half of its original stocking (unknown cause) and become a haven for staghorn alage along with Green Fuzz Algae. I'm trying to keep on top of things, but haven't been overly successful yet. The tank runs on a Small canister filter, a 100W heater and a small powerhead for the loaches to enjoy. Feeding is done once a day with bug bites and a 1/4 algae wafer. Plant list is on my tank thread, as there are too many to name.

This is one of my many 29's. It was setup on Feb 14 2025.

The lovely d39's were moved to a 65 and i put some elizabeth in this aquarium but ended up with only females - since they are wc and i don't want to mix with another catch location they are orphaned (the male was killed by a a. brevis which was mistakenly included by the seller as an elizabeth (mix catch)).

The current population is 3 female elizabeth; some humming bird tetra (Trochilocharax ornatus); some morse code tetra and a group of tucano tetra. More recently I added a pair of Nanochromis transvestitus under the presumption that the elizabeth would not be territorial since there is no male. So far (7 weeks) there has been no issues.

Most of the plants have been in there 6+ months and are well established 'cept for some purple repens on the right front. It took the pearl weed about a year to adjust to the change in water chemistry and stop producing algae but it seems to now have stablized in this aquarium and another blackwater 29.

Ec was 37 and ph is somewhere south of 6.3 temp around 76.

Here is one of two 20 gallon long black water tanks in my fish room. A pair of Apistogramma cacatuoides Lemon Candy morph imported from the Czech Republic and 10 Hemigrammus erythrozonus inhabit the tank. The Cockatoo recently spawned and there are around 40 plus fry. The substrate is fine black sand. The substrate plants include several varieties of Anubis and cryptocoryne. Four pothos plants occupy the rear rim of the tank. On the substrate are oak leaves, alder cones, catappa leaves, cholla and stones. Therefore the water is a soft golden tan color. Each end of the tank is home to a AC30 and Tidal 50 HOB filter boxes. The heater is a 200 watt Olushy. Some Chinese brand of LED lights adorn the roof of the tank. Water TDS 10 ppm, temperature 78F, pH 5-6.

Here it is ! The aquarium of your dreams full of aquatic life from distant lands and sure to be the focal point of your home and the envy of your friends .
I call this beautiful aquarium “ Endler’s World “ . What started as five feeder guppies from my favorite pet shop has blossomed into this stunning school of exotic live bearers . There are five Platy’s but they just aren’t taking off .
This is a twenty gallon high aquarium, the most functional and useful size , with no bothersome substrate . No top either to let the 26 watt compact fluorescent light bulb shower its invigorating rays on the lush growth of Hornwort . An air driven sponge filter and a Fluval 100 watt submersible heater maintain the sparkling waters at a clear and wholesome 78 degrees Fahrenheit . Water is my proprietary blend of reverse osmosis and tap water . Stare long enough at this magnificent display and you’ll soon want to duplicate it in your own home .

Welcome to my 29 gallon, Lake Inle Sorta-biotope. It is relatively new and still a work in progress; I just rescaped it a couple weeks ago. But I'm enjoying how it's coming along.

Setup:
Mixed black and brown sand substrate; granite stones, Aspen driftwood. I run two tiny sponge filters to keep mulm under control. It is illuminated by a 24" Dymond LED grow light hanging from a DIY wood/bamboo holder.

Central to the design of this setup is the floating island. I made it from blue insulation foam painted with acrylic, then covered in assorted mosses and liverworts. Herbs and flowers (chives, dwarf oregano, dwarf basil, Corsican mint, calendula, and some madras rice and red sorrel that's still getting started) grow through holes in the island, their roots draping into the water below. The island is anchored in place by bamboo stakes, just like the real ones in Lake Inle. It is inhabited by various isopods and micro land snails.

200w heater keeping things at a comfy 73F.
I add a heaping teaspoon of Seachem Equilibrium during water changes to keep hardness between 8 and 10 degrees.

Critters:
Livestock includes a blue Gourami (Trichopodus trichopterus), schools of Inle barbs (Sawbwa resplendens) and rosy Loaches (Petruichthys mango), green Neocaridina sp. and Amano (Caridina multidentata) shrimp, and assorted snails. They get fed a rotating assortment of crushed flake, sinking nano pellets, and frozen daphnia.

Aquatic plants include hornwort, various crypt species, and Sagittaria, which I just noticed I misspelled in the video.

Thanks for looking!
