Should I buy it?
Yoyo Loach
Botia almorhae
Also known as: almora loach, Almora loach
Fishori provides conservative planning guidance, not guarantees.
Based on multiple reputable aquarium care sources with strong agreement. Use the numbers here as planning defaults — your room, water, and routine still shape real-world outcomes.
An active loach that eats snails, shrimp, and harasses its own kind in small groups. Playful in the right setup, destructive in the wrong one.
Best for
Community tanks 200L or more where a group of three or more can establish a stable social hierarchy among rockwork.
Avoid if
You keep shrimp, Malaysian trumpet snails you want to retain, or nano fish under 4 cm.
Top things that go wrong
- Shrimp & snails. Shrimp: depends on the individual fish. Some leave them alone, others hunt cherry shrimp down within a week of meeting them.
Common mistakeTwo yoyo loaches in a 60L. Two fish establish a dominance dynamic that stresses both. Get three or more with territory structure.
What most shops don't tell you
- 1.Spawning, breeding, or rearranging territory can make normally calm fish surprisingly aggressive in short tanks or with rival shapes.
- 2.Large minimum volumes still need real footprint: length and width for turning matter as much as the litre number on a sticker.
- 3.Buying for juvenile size in the shop tank. Budget for adult length and turning radius, not the inch-long fish in the bag.
- 4.Group of five or more in a long tank. Secure rockwork. Expect boisterous behaviour and rehoming if the tank runs short.
About this species
Active 15 cm loach with distinctive yoyo markings. Grows substantial and turns territorial in short tanks. A serious snail hunter, not a safe default for ornamental snail displays.

Common setup sketches
Conservative patterns from Fishori fields — still run the pair checker for every species you add; sketches are not a stocking guarantee.
Avoid “one of everything” baskets — Yoyo Loach belongs in a plan built around territory, line-of-sight breaks, and matched water chemistry.
Tank mate intelligence
Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for Yoyo Loach against your own reading before you buy.

Behaviour, temperament, and what to watch
Prose and lists come from the same record: read temperament first, then glass-level signals so you are not surprised after day three.
Yoyo Loach is semi-aggressive: stable in a calm tank, pushy with weaker fish when stressed or crowded. Holds territory on substrate, in caves, or at the surface film. Break the sight lines with hardscape to keep the resident off the visitor.
Stress / aggression triggers on file
- Crowding and limited territory
- Similar-looking fish in the same tank
- Spawning, for any breeding pair
Fin nipping: Not a habitual fin-nipper, but individuals can still test fins under stress or in a crowded tank.
Predation: Not a predator toward similarly-sized community fish. The usual community caveats about mouth size still apply for very small fry or shrimp.
Territory: Holds territory on substrate, in caves, or at the surface film. Break the line of sight with hardscape, and avoid placing the tank where the fish can see its own reflection.
Planted tanks: good — easy plant ideas
In the glass: typical and warning signs
- Busy at feeding time — expects food to hit the water predictably.
- Shoaling/schooling: most colour and confidence show when the group meets **5+**.
- Clamped fins, gasping at the surface, hiding non-stop, or refusing food after the first week.
- Rapid breathing when parameters swing — fix ammonia/nitrite first, then reassess mates.
- Chasing one individual repeatedly, torn fins on tank mates, or food theft every feed.
- Corner guarding, flaring, or body-blocking — territory is normal until it becomes relentless.
- Separate or rehome if injuries appear, one fish is pinned, or feeding becomes a daily chase.
- If water is stable but behaviour worsens, reduce stocking or remove the highest-impact species first.
Fish behaviour can vary between individuals and tank setups. Always observe new fish closely after introduction.
Care parameters: water, food, inverts, grouping
Chemistry and group rules sit here so you are not re-reading the same line from tank mate or temperament blocks. Swim level is in the plan grid above.
Hardness
medium
Diet
omnivore
Mixed diet: a quality flake or pellet as the staple, with frozen or live foods two or three times a week.
Shrimp & snails
Shrimp: depends on the individual fish. Some leave them alone, others hunt cherry shrimp down within a week of meeting them.
Shoaling species. Buy 5 or more of one species together. Smaller schools sulk, lose colour, and redirect their schooling energy at whatever else is in the tank.
Egg scatterers and schoolers still spawn in stable tanks. Have a plan for the fry, or accept that the parents and tank mates will eat them in a community setup.
- Hold 22 to 28 °C steadily on a real thermometer, not the dial on the heater.
- Aim for pH 6 to 7.5 and a hardness you can re-test in two weeks. A one-time strip in the shop car park is not a water test.
- Schooling species. Buy 5 or more from the same tank on the same day before adding any centrepiece fish.
- Tank volume meets or exceeds 200L published minimum for adults.
- You can stock at least 5 individuals (group welfare).
- Heater can hold 22–28°C without cooking cooler-water tank mates.
Explore and stocking hubs
Same library as the rest of Fishori: tank-mate index for this species, category peers, guides, and litre-based stocking lists where min tank on file is within the hub volume.
Plan with tools
Pair-level rules and multi-fish stocking use the same conservative engine — add this fish in the tank builder only after mates pass pair checks.
Filtration & heating
A 200L minimum tank needs a filter rated for at least 800L/hr turnover and a heater to hold 22–28°C reliably.
Plant suggestions
Yoyo Loach does well in planted tanks. Plants compatible with 22–28°C and pH 6–7.5:

How Fishori evaluates compatibility (same logic as pair and tank tools).
- Seriously Fish. Botia almorhae
Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).
- FishBase. Botia almorhae
Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.
- Wikipedia. Botia almorhae
Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
Evidence notes
- The Seriously Fish profile for the binomial in this record was successfully reached as the primary aquarium reference.
- FishBase contributes natural-range size and habitat context. Translate those numbers through your heater, your water report, and your tank footprint before stocking.
- Wikipedia is only cited if the article URL returned OK. Use it for orientation, not as the only care sheet for an import.
- All compatibility text reflects typical hobby experience and the Fishori model. Individual fish, shop stress, and the order tank mates are added in can still defy a single-paragraph label.
- Fishori profiles work from typical aquarium trade sizes and hobby care norms. Specialist site checks and literature review for this species are not yet recorded here, so the ranges on this page are planning numbers rather than guarantees.
