Can Freshwater angelfish Live With Cardinal tetra?

Both are South American fish that do well in soft, acidic water, and the numbers agree: 24 to 29 °C and pH 6 to 7.5 suits both. Non-predatory, small-to-medium cichlids are even among the cardinal's best tankmates.

The angelfish is the question. It is a good community fish that may eat small fish such as tetras, and a 3.5 cm cardinal is small beside a 15 cm angelfish. An angelfish also needs a tall tank of at least 200 litres, which at least gives a big school of cardinals plenty of room.

Keep ten or more cardinals, plant tall-leaved plants such as Amazon swords and Vallisneria, and accept that a large angelfish may pick off some of the school. Feed foods small enough for the cardinals, such as fine flake, micro pellets and small live or frozen foods, alongside the angelfish's larger pellets, so the school is not left hungry.
