The guy said the large ones are at least 8ft long x like 4ft wide

The med ones id say were like 5ft or 6ft x about 2ft wide ... and the small ones were probablt 3ft x 18"

The round ones, the guy had one set up as a fish pond with deck built around it ... the pond it self was probably a 6ft across

Not bad size at all ... I have been thinking about changing my croc set ups and down sizing ... put all the small crocs in tubs on a rack stacked 2 high, tubs like what your thinking .. I considered using the waterlands but shipping is just to expensive on them.

I emailed you a few days ago, did you get it?
