Well, really, let's face it: there are plenty of species of fish (like Paradise Fish) that, once successfully bred, can easily overwhelm one's ability and desire to raise all the fry to adulthood, and/or can outstrip the local market if one is selling to a LFS. Less of a problem if the aquarist is willing to ship them in dribs and drabs around the country, but for inexpensive fish many can't be bothered with this option.
How long are you willing to raise the feeders...of whatever species...while growing them up to the size you desire? How much space do you want to devote to this? Your frogfish looks at least several inches long; how much time and effort is required to raise feeder fish to the point where they are worth using for that purpose?
I've used various species of fish as feeders simply because of an oversupply of them, especially during the last couple years when Covid has limited the options for dragging them into town to trade in. I don't set out to raise them for feeders; I am forced to that end by circumstances. I can't believe sometimes how a species for which I search for years goes from being the Holy Grail of fishkeeping (for me) to a tank full of feeders in less than a year...
Seriously...get that anglerfish onto frozen foods and pellets. Your life will be much easier, and watching a live fish get inhaled gets very ho-hum, very quickly.
