Help. I have a 29 gallon freshwater tank. I have an angelfish, a puffer, a betta, two tetras, a couple sharks, a gromie, a catfish, placostamis and a japanese blue crawfish. I would like to look into a swordfish, but am not sure if it's even a possibility. Can someone help me with this? I just need some basic info, and if it's even something I am able to do right now.
