Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.

Profile data confidence: medium. Driven by the lower-confidence profile (Kuhli Loach): Typical care sources — trade names for this fish get mixed up, so verify the ID before you buy.
