Hi everyone, I am brand new to this hobby. I had a tank when I was a kid, but haven't had one since. I saw this app and saw everyone giving their personal experience. I hope I can get the same type of advise so I can succeed in this hobby. I currently have a 20 gallon freshwater tank with 2 platies, 5 mollies(different kinds), 2 tiger barbs, 2 catfish, and 1 algae eater. Unfortunately I have a case of ich already that I'm treating with rid-ick. I have a 55 gallon tank that I'm going to set up in the next few months. My ultimate goal in this hobby is to have a saltwater reef tank which I'm currently afraid to start.
