I keep a close watch on them and will remove him if need be. But for now he can stay.
I love having real plant but wish I had better lighting and a co2 thing.
I hear ya, I've found a great option for lighting is to buy slightly damaged lights direct from wholesalers on eBay. I got two totally functional setups with dual bulbs for $50 each:
The brackets on both of mine were installed upside down but they don't produce much excess heat so I keep them sitting directly on the tops of my 20 long tanks. They're slightly too long so they jut out from the sides, but I don't really care
