Is there any short plant/vegetation that will cover, or nearly cover, my entire tank bottom? I think I'll have to wait until I upgrade my lighting before I move on this final piece of the puzzle. I have gravel, with no reall good plant substrate, but it is rich in nutrients and the tank is very well stocked and fertilized. I have a modest CO2 kit, and my current lighting is about 1 watt per gallon. I also have clown loaches, a gold nugget pleco, and a red finned shark. The red fin nipped away at dwarf baby tears, and I don't think I had enough light for them anyway. Any suggestions as to cover? I reeally want it to spread throughout the bottom of the tank...I have a need...a need for green.
