I'm in the process of rebuilding my Oto tank and have a void area I'm looking to fill. I have quite a few crypts on the right hand side going towards the middle. I have some L. Repens and L. Arcuata grouped in the rear from the middle to the left. What I am looking for now is a small plant that I can place in an open area. The trick to this is that the open area is where my HOB is.
