I have a few small discus in my 110g tank mixed with 30+ 4 to 5" discus. They don't do very well with the big boys and may be stunted in their growth. They need to be rehomed to a smaller tank. They are about 2 to 3" size. There is one blue diamond, one pigeon blood, one gold discus, and perhaps one red melon.
If you are interested to try out discus and have something (plant, fish, anything) to trade, you can have them. If no one offers trade, then the first one who wants them free will get them. I am located at Maryhill Bypass area, just a few minutes from Port Mann Bridge.
