I might go and get a 29 gallon aquarium fully equiped on Friday for only 45 dollars. Just doesnt have stand but it does come with 8 tiger barbs.
Bored thought i would share
Don't get silver dollars unless you aren't planning on getting live plants. Plus the silver dollars grow quite fast and they get to be way to big for a 29 gallon tank. Tiger Barbs are cool. I would also get some angelfish. It's all up to you. The possibilities are endless...
