I disagree with you on this one.Either of those guys will tear apart your plants (at least in my experience). My EBA's and GBR's love to rip plants apart.
They SHOULD color up once theyre out of the stressful environment. Definitely do NOT get 2 unless you KNOW theyre male and female. They WILL fight, especially in a 29 gallon tank.
In a 29 gallon you could do 1 Ram, a small schooling fish that likes warm temps (Rasbora Hets) and a small school of Kuhli Loaches. Those Rams really like WARM water, like 84 is perfect, so finding compatible tank mates is a little tricky.
@DuaneV : You'te talking about GBR's in your post and later about Bolivians.Yes, you can keep Bolivians cooler, but in my experience they do better in warmer water. I keep mine at 82. And mine shred any plants I have with them. They literally tear apart my Amazon Swords, Dwarf Water Lettuce roots, Banana Plants, Java Ferns, etc. Ive stopped keeping plants with them because of this. Could just be my bad luck, but it's all the experience I have to go by.
