I have a 5 gallon tank and I know you can't keep much in them I have limited space available so it was the best option for me. I currently have two male guppies (my third just died ) and a tiger snail. I was wondering if there is any one fish that grows no bigger than and inch and a half that I could put in with them? I'm going to put more plants in my tank before getting another fish because when I bought guppies I wasn't aware that they will fight with each other. I was thinking about an endler but I'm not sure if they are sold around where I live so I was also tossing around the idea of a molly. Any suggestions will be appreciated.
