please help me identify this fish and whatever this other stuff is...

i recently bought this fishtank on craigslist (42 gallon bowfront). it came with some fish (1 cory cat, 2 neon tetras and 2 unknown). i cleaned it really well and cycled it. i put the fish in along with progressively adding the fish from my 10 gallon. i really want to know what these fish are and i really want to know if i should be concerned with whatever is growing on the glass. any help at all would be very much appreciated.

Might have a slight obsession with my fish

Stuff on the glass looks like snail eggs
