I got a used 29 gal tank from a friend who was keeping cychlids. I plan on using hot water and salt to wash it out, followed by many, many rinses. Is this suitable/sufficient? I plan on setting it up for my Vitts, or Bicolor. I realize Bicos are far more terrestrially based than Vitts, but I really like the tank my Vitts are currently in, and my Bicos are in a temporary home. What if I try and make it a deep low tank(like the opposite of vert), do people do this? Thanks for any and all tips/suggestions!
