She looks a lot like your Aimi! Though I see hints of Spooky's fins turning pink...
As for what is in the tank: java fern, crested java fern (basically the same thing, but thinner leaves that kind of split into small fingers at the end), one moss ball, one stalk of lucky bamboo (with leaves above the water), anacharis that will soon take over the tank, and duckweed thinly covering the surface.
Because of the duckweed there is also one snail and a million other critters that she is always hunting. It is fun to watch!
