eat everything but their own fry and similar fry as i lost a few 134 wrigglers in 333 tank and have since found them grown up at 3-4cm
i have seen peppermint b/n activelt hunt small fry that sleep close to the bottom of the tank at night
i have shrimp in with my zebs and they keep shrimp numbers from exploding...

but you do some some smaller ones making it up the rank to adult size...
vampire plecos though smashed the shrimp population down a bit recently... must of got the taste for them
