Then you use a refugium.
I've thought of doing something similar with a
livebearer as prey and a larger predator fish. But you would need a large
tank with lots of room for prey and comparatively little space for the
predator. Not that it's impossible, just not suited to a 50 gallon tank...
unless the predators are quite small and few.
It works in 1500 gal + tanks. You don't have any this size? >;-)

As with any predator/prey relationship, I would expect you would need a
very large sandbed full of inverts to supplement just one sucker.
Otherwise the sucker/s will clean out all the prey and the prey won't be
able to reproduce. I've thought of doing something similar with a
