10-Gallon Low-Tech Jungle Aquascape (Beginner)
A 10-gallon Jungle scape, planted to overgrow itself: dense, layered, and low-maintenance once it has closed in. It is a nano tank, where every decision shows. No CO2 and no dosing regime — slower to fill in, far more forgiving, and cheaper to run. 9 plant species, Spiderwood and River Rock, and 2 livestock groups checked against each other for compatibility — every quantity below sized to 10 gallons and every plant chosen for a beginner.

Everything below is generated for this 10-gallon Jungle build — 9 plants, 2 livestock groups, and gear sized to 10 gallons. The studio does the same for your tank, free.
Hardscape — what to buy and how to place it
Spiderwood is pale bleached azalea root — a compact knot with many fine roots spreading out of it and tapering to hair-thin ends. Tannin release is mild and short-lived, so the water stays largely clear. Two things happen early and both are normal: it floats until it waterlogs, so weight it down for the first week or two, and it grows a white fuzzy biofilm within days of going under. The biofilm is a harmless fungus that feeds on the wood sugars — shrimp, otocinclus and snails eat it, and it disappears on its own within a few weeks.
River Rock is smooth, rounded and water-worn, in mixed greys and browns. River rock is inert and neutral in the water. Use several clearly different sizes and half-bury the larger ones. Rounded stones all of a similar size read as a bag of gravel; the same stones graded and partly sunk read as a stream bed.
Pairing Spiderwood with River Rock works because they do different jobs: the stone anchors the base and holds your substrate contour, and the wood carries the height and the movement above it. Let them touch — wood resting into a stone, sand banked against both — so the two read as one structure rather than two separate features sharing a tank.
In a Jungle scape the hardscape is scaffolding, not scenery. Within a few months the planting will hide most of it, so place it for what it will support — surfaces for epiphytes, a shaded cave, a branch to break the plant mass up — rather than for how it looks bare on day one.
Substrate
Aqua soil or capped organic base, capped with fine natural gravel/sand cap, built to about 2–3" and sloped higher at the back. A nutrient base keeps low-tech plants fed; cap with fine gravel. Slope higher at the back.
A capped nutrient base is the engine of a low-tech tank, so the one rule is to leave it alone. Vacuum the cap, never the layer beneath it — driving a siphon down into the base releases everything it has been quietly storing and can gas a tank in an afternoon.
Because this plan carpets the foreground, keep the front of the substrate shallow and level — around an inch is plenty — and save the depth for the back. Carpets are planted into a flat bed in small clumps a couple of centimetres apart, and they spread sideways to meet; planting them dense enough to look finished on day one wastes plants and traps debris.
Amazon Sword, Radican Sword and Echinodorus 'Ozelot' are root feeders rather than water-column feeders, so they want depth and a root tab more than they want dosing. Give that part of the bed the extra depth.
Plant list & placement
Plant back to front, into damp substrate with the tank only part-filled — it is far easier than fighting buoyancy in a full tank. Hornwort is the tallest thing in this plan at around 24", so it sets your back row and everything else steps down in front of it.
Tiger Lotus (Green) is the fast grower here — green-leafed Tiger Lotus. Bulb plant producing large dramatic round leaves. Trim surface leaves regularly to keep underwater growth. Adds tropical drama to a layout. Expect to be cutting it every two or three weeks once it establishes. Top the stems, replant the healthy tops in the same group and discard the old bases; a stem bed replanted from tops stays dense, while one left to grow on goes bare at the bottom.
Anubias gracilis, Anubias hastifolia and Singapore Moss are epiphytes and must never be buried. Tie or glue the rhizome onto your hardscape and leave it fully exposed — a buried rhizome rots, and it is the single most common way a beginner loses an Anubias or a Java fern. Only the roots may touch the substrate.
Hornwort sits on the surface, which does two useful things and one inconvenient one: it shades the tank, which calms most fish and suppresses algae, and it strips nitrate fast — but it also cuts the light reaching everything below, so thin it out by hand whenever it covers more than about half the surface.
Group the stems rather than spacing them out. Amazon Sword, Radican Sword and Echinodorus 'Ozelot' each want to be planted as a block of stems an inch or so apart, cut to slightly different heights so the group fills in with a rounded top instead of a flat hedge.
Every plant here is a hardy, forgiving species. None of them need CO2 to survive, and all of them recover from being neglected for a fortnight — which is the right way to start, because the tank should be teaching you the routine rather than punishing you for missing it.
Stocking
At 10 gallons this is deliberately a single-group tank — Chili Rasbora works the open middle water. One species kept properly in numbers is a better-looking tank than three species kept in twos, and in a tank this size it is also the only honest option.
Keep Chili Rasbora in 8 or more. These are not decorative numbers — a shoaling fish kept in threes spends its life stressed, colours down and hides, and people then conclude the species is dull. The counts in the list above are already scaled to this tank.
Blue Dream Shrimp is the clean-up crew, and in a planted tank it earns its place — grazing biofilm and soft algae off the hardscape and leaves faster than you can. Add it last, once the tank has some algae to eat, and drip-acclimatise rather than dumping the bag in.
- Chili Rasbora — Keep Chili Rasbora in a group of at least 8 — kept in ones or twos they get stressed, shy, and nippy.
- The Singapore Moss is in this plan for the shrimp, not for the look. Newly hatched Blue Dream Shrimp are small enough for almost anything to eat, and a thick mat is the only cover fine enough to hide in — it is what decides whether the colony grows or just holds on. Let it fill in before you add fish.
With Blue Dream Shrimp in the tank the constraint is predation rather than aggression: adult shrimp are safe here, but assume any fish that fits a shrimplet in its mouth will eat one, so give the shrimp moss or dense planting to breed into. Every pairing was run through Skapelab’s compatibility engine and anything returning even a caution was swapped out rather than published. Check any substitution you make there before you buy.

What the first two months look like
| Week 1 | Hardscape in, planted, filled and running with no livestock. Start the photoperiod short — six hours is plenty — because the plants are not yet growing fast enough to use more, and the surplus goes to algae. Your Spiderwood will still be trying to float, so keep it weighted or clipped down until it waterlogs. |
| Weeks 2–4 | Cycling, and the ugly phase. Brown diatom dust on the glass and hardscape is normal in a new tank and passes on its own once silicates are used up. Some plants will melt back and regrow in their submersed form — that is conversion, not death, so trim the mush and leave the roots. Do not stock until ammonia and nitrite both read zero. |
| Weeks 4–6 | Stocking begins, a few animals at a time with a fortnight and a water test between additions. In a tank this small there is no margin — one full stocking list added at once is the classic way a nano crashes. The first real trim happens somewhere in here, and the tank stops looking newly planted. |
| Months 2–3 | Growth closes over the hardscape and the scape becomes what it was designed to be. From here the job is thinning rather than growing — take out whole stems at the base instead of shearing the tops flat. |
Care schedule
| Daily | Feed lightly — as much as they clear in a minute or two — and take ten seconds to count heads and look at the plants. |
| Weekly | 27% water change — about 3 gallons — using a jug and a length of airline. Wipe the glass, vacuum the open substrate only, and dose a light all-in-one fertiliser. Trimming is occasional rather than weekly at this growth rate. |
| Monthly | Rinse filter media in old tank water — never under the tap, which kills the bacteria colony you spent six weeks growing. Test KH, GH, pH and nitrate. Check for anything the weekly routine keeps missing behind the hardscape. |
| Every few months | Thin the slow growers back hard once or twice a year, divide anything that has outgrown its spot, and top up root tabs around the heavy feeders. |
