Is this normal for a banana plant?

[JCarnes]

This is my first planted tank and I have 4 banana plants. Three have stayed small and grown new new leaves but one is out of control. In the past three days it has grown what I thought was the start of a new leaf but it has now reached the top of the water line! This is a 55 gallon tank!

Is this normal? Does it mean anything like not enough light or too much liquid plant food? Just wanted to know if this has happened to anyone else.

Very normal. All of mine do this.

They do that all the time, I've heard some will flower once they reach the surface? Not sure never seen it
