I have a friend who manages this resto that has live groupers (for food), in a 5' x 3' x 2' tank with an Eheim canister filter plus a Rio 2100-driven venturi skimmer. There are normally 30 6" to 7" groupers in any given day, but the tank always suffers severe losses (deaths), with the mortality sometimes reaching 80%. What measures can be done to minimize losses, just so the fish survive for a couple of weeks (before being cooked)?
Since the groupers are housed for food (and not as pets), I put this in the Fishing forum. Hope someone can help.
