Hi. I'm pretty new to the aquarium community but hope to learn a lot from people on this site. My husband and I have a 40 gallon tank that houses our fresh water community fish. (1 fancy guppy, 2 red wag platies, 3 gold barbs, 1 ghost shrimp, 1 pleco, and 1 Chinese algae eater). We also have an empty 15 gallon tank and are unsure of what we want to do with it. Maybe turn it into a betta tank? I don't know but hopefully we'll figure something out.
