I believe I saw it here and other sites that some people put rainbows with their discus? Prior to owning discus I had rainbows and found them to be very active and ummmm, sorta dumb. What type of rainbows are people keeping with their discus if they are keeping them together?
I have five 1.5” rainbow fish in with my discus. They all get along fine. My rainbow fish completely leave the discus alone and visa versa. All in all they make good tank mates for discus. I have had them in my tank for around 2 years now and have not lost any.
Those are nice, I never owned those, just the bigger ones . What size is your tank and how many discus do you have in there too? What temp do you have the tank?
