I passed by there last week, and Warren has more LPS/SPS frags in his two new 180s than he's ever had. (He's probably not carrying the 25 cent @ feeder shrimp any more, because the new tanks take up the space they once occupied - so it goes. I'll miss those feeders, as will my Marine Betta.)
Were they ghost/glass shrimp? If so, they’re quite easy to collect. My kids and I used to do this as the only source of food for our old estuary tank. We used to collect them by running a 3ft seine net up against the marsh grass. We’d locate small pools that were isolated by the low tide. It’s like shooting shrimp in a barrel. You’ll catch all kinds of stuff, keep what you need, return the rest.
You can keep the shrimp in a fresh water tank to kill any parasites (well it killed the ones you could see anyway). We’d collect a bunch before it started getting cold, cause collecting in the winter wasn’t super productive, but it was super cold.
