Can you get a closer pic? Doesn't look like wisteria to me...
The major difference is that wisteria is a flowering, stem plant. It will have that one main stem with the leaves coming off of it...water sprite on the other hand is an aquatic fern
The guppy tank at my moms has had mts for years..once i got rid of the goldfish i started seeing them again..now they are starting to breed^_^ i keep fishing them out and bringing them to my 40 gallon ..im sure i can give you some next time i go snail hunting..witch will be next water change so soon ish.
The big tank and the betta tank have sand I scooped out of a local creek. I like it because it is dark, but not unnatural. The betta tank also has the remains of some compost soil because I tried to set it up as a walstad at one point. The cory tank has light playsand.
