It looks amazing. You've got so many plants in there that silver dollars wouldn't even be a problem.
Cichlids (at least angelfish anyways) love living in heavily planted tanks, so you might have a good home for them if you wanted to start a cichlid tank.
Thanks for the nominations for TOTM but how do I enter my tank for it, I've tried a couple of things but not sure what I'm doing!!!! Will my tank go on the list atomatically?
