Here it is now! I added some wood that I found at the ocean a while back, and replaced a couple plants. There's only a bunch of snails in it, so I don't know what fish to put in such a small tank. Any suggestions?
Thanks for the wonderful comments everyone! I'll search around for a betta! I might get a small school of cories for my larger tanks (29 and 46 gallon) because I don't have any bottom feeders in them.
