Whats the strangest combination of fish you've seen in a tank?

[shenzhenluohan]

Today while on a tutoring job I saw 3 Blood parrots, a pile of livebearers, a male betta, a small BGK, a featherfin cat, and 6 tiger barbs in a 200 liter tank, and everyone looks happy and healthy!! My student said she's had the tank with the current residents for over a month with no problems.
So what combos that shouldn't work have you come across?

the strangest combination of fish i have ever seen was goldfish with tropical fish in an unheated tank with lots of livebearer's fry!!!!

I see that quite often here, but room temp. is 25-35 most of the year so people figure they can get away with having the two types of fish together i guess.

My uncle once had a 12" Red Devil with a 8" Fahaka Puffer with a 9-11" Red Eared Slider Turtle ands some amano shrimp which never got eaten they were to fast.

The Indian restaurant by my house (now closed) had a 30 gallon with 10 or so mixed goldfish, two koi, three iridescent sharks, one silver dollar, half a dozen fancy guppies and a betta. Everytime we went in there they had a different combo but that was the funniest. At least they weren't afraid to but a betta in a community tank!

Clownfish, blue damels, guppies, platies, lionhead golfish, and some catfish in a train station in Japan.
