tvwong, how do your blue hippos get along? I upgraded to a 210 and ordered 3 little ones, unfortunately two of them were so so skinny, would never eat and finally died. The other one is fat and happy, will be going in to the 210 DT tonight after hypo because the other two had a spot or two of ich. Now I am worried about ordering a couple more as I heard they will even fight in a big tank. Nice tank by the way.
