Profile confidence: low
How we decideFishori checks adult size and predation risk, behaviour, water requirements and tank needs before giving a verdict.
150L
Combined minimum footprint reference for these two species: about 150L (larger active fish often want more length).
Columbian Tetra is a fin nipper and Angelfish is vulnerable to nipping — long fins are a common target even when water parameters match.

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 (Columbian Tetra): Typical care sources — real tanks still vary.
