So I'm probably not going to attempt this but...

would I be able to make a half land, half water terrarium with both frog and fish in it?

I already asked about this on a fish forum and the responses were good...but what do you guys think?
Like I said by no means am I actually going to try this without proper research and stuff but I was so curious.
With proper filtration and cycling do you think this could work?
Thanks in advance!
