My captive population will eat from my hands and will even swim through my submerged fingers! In fishes, this kind of bold behavior is usually associated with an aggressive personality – but with S. parvus, this is never the case. These fishes are eternally playful. I have never noted any aggression whatsoever among populations of Red Flash. S. parvus truly enjoys the company of their own and keeping single specimens can be considered rather cruel.
Red Flash is not choosy regarding their diet. All foods including flake food is eagerly consumed. They do have fast metabolisms and should be fed on a daily basis. This is a subtropical species and room temperature aquaria suit them perfectly.
