not an aggressive species, though the
males do tend to be a bit territorial. They function well in community
environments as long as they are grouped with similarly docile species.
Bleeding hearts, like all tetras are shoaling fish. They travel in
packs. You can add a single tetra to
your aquarium. But adding four to
six allows them to frolic as they would in their natural habitat. There
is nothing quite so satisfying as watching a group of fish swimming in
a school as they would in their natural environment.
Bleeding hearts originate from waters teaming with predators. Their
slight stature delegates them relatively low in the food chain. Thus
they instinctively hide among plants and debris as a survival
mechanism. They thrive in well planted fish tanks. They tend to swim
midlevel in your aquarium. They also tend to prefer subdued lighting.
Bleeding hearts are omnivorous. In nature they survive on a
combination of plant and animal matter. They will readily eat just
about any freshwater tropical fish food you choose to give them. Tetras
are notorious fin nippers. They should not be kept with long finned
fish species such as angelfish or bettas.
