I've have nothing but good things to say about Blue Rams. I've got 3 in my 20 gal Amazon-ish tank with a group of about 10 neons and a few painted tetra. Their colors are really starting to come out these days, especially since I put a Flora Grow bulb in there..it seems to make their colors really shine. The red streak in their eyes just jumps out at you against the black line running through it. As for behavior, I've never kept any other "ciclids" so I can't really compare. They do however show some really neat territory practices, even if they are pretty shy and all talk for their actions....it's still pretty cool to watch. I wish they would put a little more of a scare into the Neons, they are just too used to the tank and never really group together as much....maybe my tank is too small and they can all stay in eyeshot of each other, i dunno?? They don't really get too big either, so maybe consider some Bolivian Rams?? I heard they are a little bigger fully grown and a bit more aggressive. Some food for thought, GOOD LUCK!
