A friend is clearing out some 'clutter' and has a couple of tanks to offer, he doesn't know the dimensions at the time he offered them.
A 55 gallon FREE. A 40 gallon FREE, or a 40 gallon octagon with stand and hood $50.

I did a search here for 'octagon' and some old posts came up, the pictures were outdated and didn't open.

I'm planning to start my beginner 'frog adventure' with either Fire Belly toads or Dart Frogs, (group friendly, nothing fragile, but bold, maybe Dendrobates leucomelas ?, still researching)

The octagon tank sounds interesting but according to dimensions I've found, it's 'about' 24x24x24
Seems to have some wasted space for ground/bottom dwelling creatures, but the shape might be interesting for 'humans' visual effect.

My thoughts with the octagon:
An island, ('around' 18"x18") a stump/broms and other plants, surrounded by slow moving cascading pools or completely surrounded by shallow water would be good for Fire Belly toads. All the glass would be open, no background attached to it.

Or 4 sides of background and do a Dart frog viv.
Or 4 sides of background and a small, front, water feature for a FBT viv.

How many "toads" do you think would be happy in this octagon?
How many for a group of PDF in the octagon? Which PDF?

Or just go with a 'standard' tank?

What are your thoughts?
Any pictures?

"Something" tells me I should get all of the tanks!

Thanks!
