Hi I'm new

[Leanne]

Hi Kurt, the frog is about 3-4cm long it is light murky brown with faint small circles on it's body and a yellowish stripe down the center of it's back. We live in Narre Warren South, Melbourne, Victoria. I apologize as the picture isn't the clearest, but the best I could manage.

Hi there Leanne, Welcome to the Forum I'm thinking maybe a Spotted marsh frog (Limnodyastes tasmaniensis) These frogs can be found in Farmland, woodland, ponds or slow moving creaks, Many situations. I'm no expert and I'm only taking a guess so don't quote me though. We have some experts here on this forum who will most definitely be able to help you.

Hi Ebony, yes the coloring is fairly accurate if anything the frog maybe slightly lighter than the photo and the stripe is a yellowy color, I have noticed that it does change in color depending on what it is sitting near

Most frogs do that. I am going to second Ebony's ID. I believe it to be a Limnodyastes tasmaniensis.

Can you describe the enclosure that he is in? or better yet a picture. Sometimes the set ups they sell are not very well suited to the frog that you have in mind.

Hi Tom,
The tank is 2ft wide 2ft high and about 1ft deep I've a heater in the water set to about 26 deg c a uv light over the tank plus a small water fall over the large log

I would recommend making part of the enclosure land.
