Anyone Know What Kind of Fish This is?

Its a small fish but not so small. Its body is redish purple and its tail is bright yellow. I saw it in a hospital aquarium with 4 other fish bigger than it. The cistern I think was 30+ gallons. I have a picture but it's kinda blurry.

Would 4 platies, 3 mollies, and 3 swordtails be ok for 10 gal. reservoir?   Would an algae eater abet my 10 gallon reservoir?   I only just bought a used 55 gal reservoir..It come next to a big pleco and catfish which i have to put into my 20 gal ?   My axolotyls cistern heat is too low?
