Can Angelfish Live With Rummy Nose Tetra?
No, adult angelfish eat rummy nose tetras since rummy noses at 2-2.5 inches are small enough to fit in a 6-inch angel's mouth.
Why
- Angelfish grow to 6 inches long and 8 inches tall, with mouths large enough to consume fish up to 1.5-2 inches.
- Rummy nose tetras reach only 2-2.5 inches and fit in an adult angelfish mouth.
- Angelfish are cichlids with predatory instincts that activate as they mature past 3-4 inches.
- Small rummy nose schools are easy targets for an angelfish that has grown accustomed to the tank.
What could go wrong
Rummy nose tetras disappear one at a time over weeks, usually overnight, with the school losing members before anyone spots the predation.

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Angelfish pair well with larger tetras like black skirt tetras, congo tetras, or lemon tetras that are too big to swallow. Rummy nose tetras thrive with cardinal tetras, neon tetras, or harlequin rasboras in a peaceful soft-water community.
