Mesh size depends on length of fish. You want a mesh that the fish cannot get its head into. Mesh can be as small as 1/8" for 1" fish and as they grow put fish into larger mesh cages. I try to use the largest mesh possible to contain the fish while optimizing water circulation and minimizing clogging by algae.
