Beginner answer
Yoyo loach works best when tank mates match its 55+ gal / 208+ L minimum, group needs, and temperament. Start with the concrete limits: tank volume, adult size, temperament, group size, water range, and filtration margin.
Top beginner-safe picks
- Same temperature range - Tropical fish usually need 72-82 F; mixing coldwater and tropical fish causes chronic stress.
- Similar aggression level - Peaceful fish belong with peaceful fish; avoid fin-nippers with bettas, guppies, or angelfish.
- Matching pH range - Most community fish tolerate pH 6.5-7.5, but sensitive species still need stable water.
- Appropriate tank size - Use the larger species minimum, not the smaller fish minimum.
- Schooling group size - Neon tetras, rasboras, and Corydoras show stress when kept alone.
Yoyo loach (Botia almorhae) should be judged by adult size and group needs, not by the small size it may have at the store.
Setup rule: Yoyo loach has a minimum tank size of 55 gallons and a recommended tank size of 75 gallons.
Setup rule: Temperament: active semi-aggressive bottom dweller. Beginner friendliness: low. Bioload: high.
Setup rule: Better tank mate candidates: none listed yet. Risky or avoid lists should be treated conservatively until the full setup is checked.

Yoyo loach quick care verdict
Yoyo loach (Botia almorhae) is currently marked low for beginner friendliness with medium confidence. The minimum tank size is 55 gal / 208 L, but 75 gal / 284 L gives better margin for behavior, filtration, and maintenance.
| Scientific name | Botia almorhae |
|---|---|
| Adult size | About 6 inches |
| Tank size | 55+ gal / 208+ L minimum; 75+ gal / 284+ L recommended |
| Temperature | 75-82 F |
| pH | 6.5-7.8 |
| Group size | 5 or more. Keep in a group with a large tank and hiding places. |
| Temperament | active semi-aggressive bottom dweller |
| Bioload | high (5 care score) |
Tank setup
Use the recommended tank size as the real target. The setup should match the fish's adult size, activity level, bioload, and group requirement. Plant cover is helpful because it creates security and visual breaks. It does not have a strong hiding-spot requirement in the current care data.
Behavior and group size
Group behavior changes compatibility. Keep in a group with a large tank and hiding places.
Aggression risk is marked medium, fin-nipping risk is marked low, and predation risk is marked low. These labels drive the compatibility checker, especially when the other fish is long-finned, tiny, slow, or shrimp-like.

Warnings
These are the failure points that hurt beginner tanks most often. Do not use guide content as a guarantee. Watch actual fish behavior, test water, respect adult size, and keep a backup plan if stress appears.
- Tiger barbs - Confirmed fin-nippers; do not keep them with bettas, angelfish, guppies, or other long-finned fish.
- Goldfish - Coldwater, high-waste fish that do not belong with warm tropical community species.
- Angelfish - Adults become territorial and may eat very small fish such as neon tetras in cramped tanks.
- Pea puffers - Aggressive hunters that bite fins and attack snails; treat them as species-only unless experienced.
- Temperature mismatch - White cloud mountain minnows and goldfish prefer cooler water than bettas and many tropical fish.
Editorial notes
How this page is maintained: This page is updated from local care data, compatibility rules, source notes, and conservative beginner-risk checks.
This page uses conservative local care data, explicit compatibility records, and established aquarium care references rather than store-label shorthand.
Combinations are reviewed before they are promoted as indexed guides, and uncertain pairs stay cautious or marked as needing more research.
The recommendations are intentionally conservative because most readers are planning beginner tanks, where water quality and backup options are limited.
