Something that I would think would work excellent is the plastic beer bottle disposible 24 case crates. They have a lattice work to keep the bottles from clanking together that makes for lots of spaces larger fish can't get in yet open enough for good water flow and O2 levels. Or any similar plastic lattice work. Bolt a bunch of the crates together in a large 3 or 4' square block and sink and keep in place with concrete blocks.
