Really ? Cardinal tetras are that kind of fishes ? I feed fish food to my fishes everyday and they still hungry to eat shrimps ?
What about others of you here ? Does you shrimps like jumping out from the aquarium ?
It so dissapoting when they die because they are nice to be kept in aquariums and are costly as well depending what type of shrimps species and grading

Tetra fish are consider semi aggressive kind of fish, the bigger the fish , more bully they are.
Peaceful fish are mostly boraras/rasbora type which suit planted tank as well.
They jump either bully by fish , lack of oxygen(at night co2 more oxygen depleted, plant absorb oxygen too when light off)
, you can set timer to off co2 when light off and on your air-stone at night.
if tank parameter not suit shrimp or tank not fully cycled , shrimps may jump out too.
