The emerald I bought, in the span of four months, grew from the size of a dime, to the size of a dollar coin. He was HUGE :notsure: I eventually took him back to the LFS where I bought him, and even they were surprised--I now visit him every other saturday in the 200g display tank they put him in. He was replaced with another small emerald which I've only seen three times--last sighting, saturday afternoon.
