I searched and read a few threads but didnt see any concrete:

would there be any issue with having a tank of multiple species?

Im thinking a frog (probably ADF) a crayfish or freshwater lobster, missippi map turtle, small catfish or some other type of fish and of course guppies.

Im aware the gupies might be eaten (probably) but do you think the other species would all kill each other?
Thanks for any info!
