One thing that strikes me about my group of smallscale archerfish is how readily they eat pellets. As a matter of fact, pellets were the first thing they ate after I bought them.
It seems this isn't so with a lot of other predatory perciform fish, such as sunfish, tiger perch, or leopard bushfish. When I have either kept these before or read the threads about them on this website, a lot of effort was needed to get them from live to pellets and it wasn't always successful.
Perhaps this is because archerfish are surface feeders, while none of those are. So they might think of pellets as more similar to the floating bugs they'd eat, than the above examples think pellets similar to the live, swimming fish they eat.
