I got a true Siamese Algae Eater a few months ago, and he's done a great job clearing a problem tank... but he's grown super fast and gotten very spoiled. I know he'd be happier in a larger tank. I love SAE's and wouldn't want to not have one, but I'd be willing to trade my big guy for a really small one, in the 1" range. Mine is probably around 2-3". I'll have to try and measure him.
