Oh I didn't know your tank was planted lol. Yeah man Bolivians are great. I have two of my own(male and female). They are so fun to watch and people may say they aren't as colorful as your GBR's but trust me, with the right care and variety in their diet, they'll light right up. Mine have yellow bellies and are red throughout their body with their tails being black, grey, with red tips. Blue on their pelvic fins too. They're great fish.
