Here is a few pictures of some of my cephs. They are in a 20 gal long tank in an east window with a shop light over them. They haven't grown much this winter,although there is some new growth. I use the straws to ID my diff clones. It gets tuff when they grow together, you loose track of which is which. This is one of two main tanks I have. I grow them all different ways, and there will be many more pictures to follow.
