What frogs/toads can I keep with fish?

nah, just siphon it out using good old fashioned lung power. you may not even have to ever do that, since it will be more like a flower pot instead of an entire viv bottom. but it will be a nice feature to have in case you do need it. and if you place a valve on the end of the, and keep it below the bottom of the tank line (outside the tank of course), after you siphon once, just close the valve. next time you need to siphon, open the valve, and voila, instant drainage.

But what is I don't want frog water in my mouth? lol
I'm just glad I don't need to make a false bottom, one less thing to confuse me...lol I'll put the tube and sponge in in case I need it.
Should I use clay balls, pea gravel, or what for the drainage layer?

If you get a valve or a locking pare of forceps you can use a turkey baster to apply suction
and don't drain all the water out so you can keep the prime on the siphon.
Then use the valve or locking forceps to stop the flow of water.

Also if you put the drainage tube with the sponge at the back of the tank on the very bottom.
I would raise the front by 5mm or so to make the water go to the back where the tube is.

Now on the choice of drainage material, I would use the clay pellets since they are porous
and can hold some moisture to help keep the humidity stable.
