Thanks for the advice! I do realize that the design of the edge makes lighting a bit of a challenge. I'm thinking I'll just stick to the hair grass and find some small background plants rather than throw my money at HC without the proper equipment. I did see some cool things called Marimo balls...does anyone have any experience with those?
Also, I think that Scarlet Badis would work pretty well in the tank. They're supposed to be pretty small and relatively inactive. Those might be better than taking a risk with the blue rams.
