Just got back from seeing these guys myself. The temensis is within a couple of inches of the pinima for sure, I can't believe how fast that guy is growing. And you must have given your man at the zoo the cichla bug since the first tank now has two small mono's in it. On a sadder note, I think that big daddy dovii is pretty close to the end, his eyes are all clouded over and he just hangs in a corner near the surface of the tank. The juvi, who's definitely in the 16 to 18" range is roaming the tank in full color. I'll post some pics of everyone up in a bit.
