New Terrarium for my Spotted Marsh Frog Help

[Kristen]

ok so dad and i went and bought a spotted marsh frog from this guy "blue tongue skink+spotted marsh frog | Reptiles & Amphibians | Gumtree Australia Geelong City - North Shore" he said he bought it about a month ago! we have put the frog back wear we found it by the drain! i also have added some small plants and rocks so that it has something to hide in or under is that ok? or should i leave it how it was? do i need to change my tank again because i have a new frog in it? the guy said he fed this frog "fruit flies" once every 7 days should i do this to or should i feed it other insects? what other things should i add in to my tank to allow it hide under? when are these frogs most active and do you think if i was to buy another spotted marsh frog that they could live together ? i would be buying it from this guy Southern Brown Tree Frog( Litoria Ewingii )& Stripped Marsh Frogs | Reptiles & Amphibians | Gumtree Australia Cardinia Area - Pakenham i no it doesnt say he is selling spotted marsh frogs but i inboxed him and he said he had 1 adult one he was willing to sell me for $39! i can copy out the email if you want proof!,and i am also thinking of buying a southern brown tree frog from him to!
would a southern brown tree frog and to spotted marsh frogs live well together or is that a no no? also could they be fed similar things? would i have to change my terrarium ? or simply just ad in more branches and sticks?
if you could answer my other question that would be great to thanks

Okay so now you have a captive bred frog, you need to re-do your tank It can't have wild plants/dirt. It can have wood/branches/rocks from the wild if you bake them in the oven (It kills bacteria)
Thats far too less! Feed him small (Or pinhead) crickets every second day, or everyday if his a baby.
They are most active in the night because they are nocturnal. Mine hide alot during the day.
Honestly them frogs are over priced. This guy in Welcome To Omagic Frogs Butterflies and Insects : Home sells them for about $10 he lives at 20 Hammond road dandenong.
Also too much for Brown tree frogs, the guy I put about sells them too. So do I for $20.
Yeah they can definately live well together! I had some in this tank here if you want ideas.

They feed the on the same things (crickets), and you have to change it anyway. For Brown tree frogs you need more branches and maybe a vine or big leafy plant.
