Bullying Problems

Adding more hiding spots such as fake plants, lily pads, small rock caves, moss hills, and flower pots could help the females rest, and also adding a little water dish on the land area could possibly save the females from drying out. I would make more barriers, plant, driftwood, log or otherwise, between areas so it's harder for Hugo to reach the females, and more peaceful for the females. If nothing works, move Hugo into his own tank, and place the tank beside the main tank so he can see the females, but not reach them. Of course, another solution is to get an even bigger tank, but I'm confident you won't have to resort to that.

I like Alex's idea of putting the females in a separate tank for a few days in order to recuperate.

My frog does this sometimes too. When he goes on top of the females, it is called amplexus. This is the mating position that fire bellies use. Basically your toad is horny
even though your toads aren't ready for mating or aren't even the right sex, he will still try. I have never heard of patrolling the water though, I would recommend the same thing that Caspian said, add a separate water dish so that the females, or other frogs don't dry out. I don't know if amplexus is what your toad is doing, but I attached a picture of what it looks like.

Can you identify if this is amplexus, or something else?
