BettaMomma, you could get a couple nice live plants for less than the $15 for decorations. Amazon Swords look great in the 2.5 gallon. Just one looks good. Two look even better. They only run about $2.50 each. The gravel I have in those 2 tanks is the browninsh round stones that Petsmart has in all their tanks here. You may need a little more lighting though. I will post a picture of my 2.5 gallon and 5 gallon as soon as I get home.
