Can Guppy live with Pictus catfish?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: medium
How we decideFishori checks adult size and predation risk, behaviour, water requirements and tank needs before giving a verdict.
250L
Combined minimum footprint reference for these two species: about 250L (larger active fish often want more length).
Pictus catfish (about 14cm as an adult) can realistically eat Guppy (about 5cm) once grown. Plan around adult sizes, not shop sizes.

- •Pictus catfish should be kept in a group of at least 5 for best health and behaviour.

Check each species’ mates list, size the glass, then verify the full stock in the builder. Methodology explains how verdicts are produced.
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: high. Checked against several solid care sources that mostly agree.
