Crypts are truly lovely aquarium plants. They are undemanding, require little maintenance and are 'easy on the eye'. What's more is they come in many different styles and this particular one is a cracker.
This particular crypt is brown and one of the reasons it is so popular in the planted aquarium. It provides a refreshing change to most plants which are green and looks particularly nice if planted in groups around stones. Other plants are available and can be found here.
