Well I wanted a few more discus so I purchased 3 marlboro reds. They're about 4" and I'm just acclimating them into the QT tank. They'll join the red turks and pigeon bloods and hopefully bring out the pigeon bloods from behind the bushes. I think I'm complete now with my 110 gallon.....but I'm going to turn the 47 gallon into a salt water tank......after lots of research of course.
