Yoyo Loach

Botia almorhae

Also known as: almora loach

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.

Checked against several solid care sources that mostly agree. Numbers here are a careful starting point. Your tap water, tank size, and habits decide the rest. How we evaluate.

Temp

Best for: Community tanks 200L or more where a group of five 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.

Common mistakeKeeping two yoyo loaches in a 60L because the juveniles looked small is how keepers invent a dominance feud in a tank that is already too short. Get five or more with territory structure and ~200L-class room — token pairs stress each other and outgrow the kit.

Top things that go wrong

  1. Shrimp & snails. Shrimp are a gamble with this fish; some ignore them, some clear a colony in days.

What most shops don't tell you

  • 1.Myth: a pair of yoyo loaches is a fun cleanup duo for any community nano. Reality: they need a group of five or more and serious footprint — two fish in a short tank invent dominance stress and outgrow the glass.
  • 2.Spawning, breeding, or rearranging territory can make normally calm fish surprisingly aggressive in short tanks or with rival shapes.
  • 3.Large minimum volumes still need real footprint: length and width for turning matter as much as the litre number on a sticker.
  • 4.Buying for juvenile size in the shop tank. Budget for adult length and turning radius, not the inch-long fish in the bag.
  • 5.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.

Numbers are deterministic planning indices from Fishori fields — not a scientific score of your individual fish.

Adult size
Yoyo Loach adults reach about 15 cm. Shop fish look smaller; stock for the adult length.
Tank size
200L is the planning floor for adult swimming space and bioload. A 244L+ tank is the more comfortable long-term footprint. Length and depth matter as much as raw litres for active or territorial fish.

Example setups

Starting points only. Run the pair checker for every fish you add.

Not recommended as a random community add-on

Avoid “one of everything” baskets — Yoyo Loach belongs in a plan built around territory, line-of-sight breaks, and matched water chemistry.

Behaviour and temperament

In the tank

Yoyo loaches are semi-aggressive, active bottom-to-mid fish that stay calmer in a proper group with room to claim caves. They can harass shy neighbours and snails. Stress and bullying rise hard when only two share a short footprint without structure.

What sets them off

  • Crowding and limited territory
  • Similar-looking fish in the same tank
  • Spawning, for any breeding pair

Fin nipping: Not a habitual fin-nipper; stressed or crowded individuals can still test fins.

Predation: Not a predator toward similarly sized community fish; fry and dwarf shrimp are still fair game for most species.

Territory: Holds a patch (cave, corner, or surface). Break sight lines so neighbours can pass.

In the glass: typical and warning signs

Typical behaviour
  • A group of five or more patrols caves and open bottom with constant contact-sport energy.
  • Snail hunting and rearranging décor are normal ownership in an honest footprint.
Stress signals
  • Two fish pinning each other in a short tank means stocking failed before disease labels.
  • Shy tetras hiding all day means neighbour choice failed — not picky appetite.
Aggression signals
  • In-group dominance looks rough and still beats a stressed pair in a nano.
  • Spawn or territory spikes can surprise keepers in short tanks with rival shapes.
When to separate or rethink
  • Increase group size and footprint before blaming ‘aggression’ for constant chasing.
  • Rehome yoyos if the tank cannot give ~200L-class room and robust company.

Fish behaviour can vary between individuals and tank setups. Always observe new fish closely after introduction.

Water, food, and grouping

Water, feeding, inverts

Hardness

medium

Diet

omnivore

Yoyo loaches are opportunistic omnivores that work the bottom and midwater for sinking foods, snails, and leftovers. A flake-only routine leaves the group hungry while midwater fish skim the surface. Offer sinking wafers, frozen foods, and the odd snail plan, and feed a group of five or more so competition does not starve shy fish.

Shrimp & snails

Shrimp are a gamble with this fish; some ignore them, some clear a colony in days.

Grouping

Schooling species — buy 5+ together. Smaller groups stress and lose colour.

Before you buy checklist
Tick mentally in the shop. Every box should be true before you pay.
  • 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

Tank-mates hub, matching guides, category peers, and litre stocking lists around this species’ minimum tank.

Plan with tools

Check mates as pairs first, then add this fish in the tank builder for the full stocking.

Filtration & heating

A 200L minimum tank needs a filter rated for at least 800L/hr turnover and a heater to hold 2228°C reliably.

Sources & evidence

Research: partially verified · Confidence: high · 3 linked source(s). We do not invent citations.

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.
