Only in some cases would it actually pose a threat. Doesnt matter what size you feed a feeder. They go down head first, thus thier fins are all the way down when eaten.
Should I breed convicts to feed off fry

Only dumb fish eat fish tail first, then the spines get caught in thier throat. Clown knifes sometimes do this. But they soon learn. Quickly.
Right. So feeders just swim straight up to a predator head on and let themselves get swallowed? Some species of gar manuever prey to go down head first after catching them, but in the overwelming majority of cases the larger fish chases the feeder and catches it from behind, swallowing the fish tail first. This is why spines evolved in fish in the first place, to make it harder for them to be eaten. The intelligence of a predator fish has nothing to do with whether or not the swallow a fish head first.
Anyway, most cons up to 1.5 inches don't have spines yet so they should be fine to use as feeders.

Whats the smallest tank I could Use to breed cons, I was hoping to use my 30g for a planted tank, but with the price of feeders it seems wiser to breed cons.. ive got a 10g and i could buy a 20L or 29g
I am trying ot do the same thing right now with a 20 gallon tank...trying to get some feeders for my dovii
allthough my knife usually catches stuff by the tail, he turns them around anyhow before he swallows them, so they should learn, mine did.
well he wont even go after feeder guppies, and his sides are completely sunken in. the LFS only offers a 24hr guarantee and its been longer then that so they wont even take him back "alive"
