leopard frog pleco's , will they eat the discus eggs ?

i have leopard frog pleco's L134 in my planted discus tank and they breed all the time .
so far i trapped about 20 out of my sump .
i was thinking of putting them in my breeding tanks , to keep them clean , however , they are omnivores apparently !
does anybody have experience , if they are egg robbers ?
am i asking for trouble ?

No personal experience mixing L134 with discus, but I wouldn't recommend it. All plecos are a risk to eat eggs after lights out, and L134 aren't algae eaters like common ancistrus. I'd be more worried about the pairs killing expensive catfish.
