Welcome to the forum and welcome back to fish keeping! This is a great place for information and support. Im sorry you had lost all of your fish in the past. I know that must have been hard for you. It sounds like you have a nice size tank! That's great!
. I have a 5 gallon fluval chi with a betta and a new 55 gallon that I just started stocking yesterday with tropical fish (5 rummy nosed tetras). I'm trying hard not to become an addict. I keep telling myself I don't have enough room for more tanks. My goal is to have my 55 gallon as a saltwater tank some day.
