I would caution you to pay close attention.
In my experience, A. Cacatouides mind their own business and
should not both them. They are substrate feeders - and I have 4 in a 10g (hoping to pair them off) with a small, 1/2 baby bristlenose pleco. The swim/hover right next to him and do not pay him any mind.
That being said, my experience may not end up being yours. I would advise close observation the first few days/weeks to make sure that the mix does not become problematic. In the same way, A. Cacatouides are pretty sensitive fish due to inbreeding (which is how the amazing colors have been developed). They do not handle stress well so I would also make sure that the frogs are not bothering them.
I think, as long as you have plenty of caves for the fish, you should be fine.
