Got it not even 2weeks ago. Went from roughly 2" to 3" and you can tell the difference in girth. I havent seen one before will be interesting to see what it turns into. Seems it may be a monster.
It got upgraded to a bigger tank. Hard to show comparison but in about a week it has grown almost another inch!. Those albino ID's were about an inch longer (they've grown about 1.5")than the redtail/lima when I got it.
