Plant identity

[fred]

So this is my first time aquascaping and I was reading some threads on here yesterday about chain stores selling none aquatic plants. My question is I know the java fern, java moss and sword plant but the other plant to the right (sorry about the reflection) I'm insure what it is. When I bought it I was told it was aquatic...but Ira not doing so great. Wondering if I should pull it out before it affects my water?

Yeah probably Wisteria, it grows differently depending upon conditions grown in.
