My kelberi are outgrowing my orinos, they are around 12" while my orinos are around 8". At one point the kelberi were just a tad bit smaller than the orinos, but they eat tons of massivore every day. The orinos eat 1-2 massivores/day and sometimes don't take any interest in the food. The smaller two orinos get picked on all the time by the kels and often will have nipped fins/tails. Planning on moving the trio into my the 150 once the azuls/monos are big enough to go into the 240. Also getting a 225 this spring (have the money), just need to figure out the best way to pick it up from california, get it into my house, and rearranging all my tanks to maximize on living room space.
