Hi All! I have what I call my peaceful tank. It's a 60 gallon high and presently holds four gold gouramis (1 male, 3 female), 2 angels (sex as yet unknown), one red tailed shark and one 4" pleco. Everyone gets along just great and it's a very relaxing tank to observe. I'd now like to add one more pair or trio that might get along with my permanent residents! Any suggestions? I'm running two aquaclear 70's. Something with a little color would be great. Thanks in advance for any suggestions.
