The cardinal tetra (Paracheirodon axelrodi) and the neon tetra (Paracheirodon innesi) are popular aquarium fish due to their bright colors and peaceful nature. The main difference lies in their coloration: the cardinal tetra has a red stripe that runs the length of its body, while the neon tetra's red stripe only extends halfway, with the blue stripe being more prominent in the neon tetra. In terms of behavior, both are peaceful and sociable, preferring to swim in large schools. However, the cardinal tetra can be more demanding regarding water conditions and is less prolific in captivity compared to the neon tetra, which is easier to breed and maintain.

Food competition (9 Species)
They can live together but you have to be careful since it is likely that the fastest fish will take all the food and leave nothing for their partners who are slow swimmers, so you have to make sure that everyone can eat.
Compatible if space is enough (4 Species)
They can coexist together if the aquarium they share is large and spacious enough for both species to feel good, as some fish may attack others to feel that they have little space and try to eliminate the competition.
