on the "huge" remark
Ok, to give you some kind of perspective of how much it's grown here's a pic of when we first got it, it was in a 29 gallon tank, it got so big that when we did the water changes it would be close to bringing it out of the water, time for a new tank, now we have a 60 gallon, moving it was a joke, it was attached to two rocks.
We've had it for a little over a year now, it has gone through multiple spots in the 29 gallon tank, it has fallen all sorts of things and has bounced back every single time. It's become one of the centerpieces for our tank. I'd say the bigger clown is a little over 2" not including tail and the little one about 1 1/2 not including tail.
Here's a pic of how it looked in Jan of 2003.
