What animals can cohabitate with them? I've read they are friendly and won't kill other species but a bit worried they may be eaten.

And what animals would make nice viewing from a glass gallery in a basement with a side on view?

There's a lot of mosquitos outside, so I'm guessing it needs Mosquito fish.

Any other suggestions.

What about terrapins? And what fish will keep the pond cleaner or clearer.
Or do I need to get in there with a squeegee




I'll get you some pics of the outside tomorrow, I get eaten alive out there at this time
TIA
