The fertilization procedure is external; hence, the released eggs might be subjected to threat.
It is mandatory to separate the eggs from the tank, as there have been instances where the parent bleeding heart tetra consumed the egg.
The eggs must be isolated until they are hatched.
Did you know: As the mating system is oviparous, the progeny is produced in multiple periods.

- Livoneca infestations.
- Nematode infection.
- Columnaris disease.
- Turbidity of skin.
- Saddleback disease (Usually attack the mouth)
Did you know: As the mating system is oviparous, the progeny is produced in multiple periods.
Setting Up the Tank – The Essentials.
|Quick Tank Facts|
|Minimum Size||140 ltr|
|Water Temperature||23-27 degrees C|
|Water Hardness||8-12 Gh (soft water)|
|Water Ph Level||5.6 to 7.2 (acidic neutral)|
The mobile bleeding heart tetra requires ample size for its movement, and you may find them swimming in the mid-depth or bottom of the tank. Hence, keeping a tank size of 15-30 gallons is recommended to comply with their mobile and social nature.
It is a one-time investment as the tetras don’t like to stay alone. Hence, go for a tank that doesn’t hamper their movement.
Given they are more comfortable in schools of at least five to ten, this will be optimal for more than five of their kind.
The red heart fish emerging from the tropical land has a lot of sand in its soil. Hence, that is an essential factor to consider while placing the substrate.
Many aquariums recommend the use of a dark substrate. Hence, the usage of dark sand can be the most optimal choice.

Moreover, chlorine is hazardous to their health, so ensure a good quality anti-chlorine is used at every water change.
Modeling a similar lifestyle for a tropical fish can be attained by following the guidelines cited below.
- The species prefer their water to be more acidic, so the Ph shouldn’t cross 7.2.
- You can leverage the fact that these are one of the few tropical fishes which don’t mind a water temperature on the cooler side. The temperature range for the bleeding heart is 23-28 degrees.
- The hardness level of freshwater is shallow, and hence, it is optimal to integrate soft water into the tank.
- The water’s nitrate concentration should not exceed 50 mg/L.
- To correctly model the environment, ensure the water current is slow-moving.
Ideal Plant Mates for Decoration
The well-behaved bleeding-heart tetras don’t eat the substrate or the plants. Hence, don’t shy away from integrating plants in your tank set-up.
