Hey everyone 
As a kid my parents bought some goldfish for me and kept them in a 29 gallon tank with a pleco (which I called a "sucker fish" and still do sometimes haha) and it never got very big and seemed to be a pretty peaceful guy. When I got my new 60 gallon tank after years of having no fish I decided to get another one because I'd really liked the one I'd had before. So I named him Spot and put him in the new tank with my betta named Smoke (after the Mortal Kombat character because he looked grayish in the cup at PetSmart, but he's since turned purple) who I'd been keeping in a baby BiOrb that I hated. But now after some late research I've found out that the particular one I got can grow up to 18" and might be aggressive. Now I'm scared I can't add anymore fish to my tank and that he might hurt Smoke.
Will he be okay in this tank with my betta and some Dalmatian mollies that I wanted or should I take him back? I mean, he hasn't showed any signs of aggression yet. Smoke was picking at his algae wafer while he was eating at it and didn't chase him or anything, but he's only 2 or 3 inches right now.
Sorry for rambling on. I'd really appreciate any advice. Thanks so much!
