Do I need a new tank? Territory problems

[Whistly]

My youngest frog by about a month who is also my smallest frog by nearly a a whole cm is extremely territorial and my 2 other frogs are getting quite a beating when they go near one of the ferns one frog has taken to burrowing under the moss to make a hiding space. Do I need to get a new tank for the territorial frog to be alone in and not have to worry about territory wars?

Lol yes Tim Tam is quite the tough customer shame that she (I think) has taken to the corner where the crane flys seem to always gravitate towards so my other two barely get any.
