Redfin Keeping

Dear Aquatic Plants,
 I volunteer at a local nature center known as Battle Creek Cypress swamp 
which is located in Southern Maryland. We are currently trying too keep a 
Redfin pickeral for a display and study. We have caught them several 
times before but every time they seem to die. Do you have any suggestions 
on how to keep them alive. We usually give them mosquito fish to eat and 
they will gobble them up.
