We have a 29 gallon tank set up with 5 platies, 3 pearl danios, 3 zebra danios, and 3 emerald cories.  One side of the tank is set up with some taller plants (wisteria, bamboo, amazon sword, and some unknown species) and drift wood, the other with a lava rock and some red wendth
 
I know it's cliche, but we were planning on getting some neon tetras in the tank for some color - we have too much silver!!  I was ready online somewhere that neons like plants to hide amongst.  We don't want to fill the tank with taller plants, and cut out swimming room for everyone else, so we were thinking of getting some shorter plants that would allow the tetras to hide.
 
Any suggestions???
 
Thanks!
