How long do Bleeding-heart Tetras live?
They live about 3-5 years with good care. Their larger size and calm nature make them a steady, long-term community member.
What do Bleeding-heart Tetras eat?
They take flake, micro-pellets, and frozen/live foods like bloodworms, brine shrimp and daphnia. Overfeeding is the main diet mistake; feed what is finished in two to three minutes.
Tank size and water parameters
A 20-gallon (75 L) tank or larger suits a group of 6. Target 73-82°F (23-28°C), pH 6.0-7.5, soft to moderate water, zero ammonia and nitrite, nitrate under 20 ppm. Keep in groups of 6+; provide plants and driftwood for cover to reduce shyness.
Common mistakes with Bleeding-heart Tetras
Usual errors: too small a group, which makes them skittish; bright, bare tanks with no cover that stress them; and boisterous tank mates that outcompete these gentle feeders.
Beginner mistakes to avoid
- Keeping them singly or in pairs — they need 6+ to feel secure.
- A bare, brightly lit tank — they want plants and cover to settle in.
- Rough or fast tank mates — gentle fish do better with this calm species.
- Overfeeding — keep portions modest to protect water quality.
