Here are young/older photos of our Koran.
We got him in Sep 04, he was about 2 inches.
Now he is about 4 inches.
They are listed as NOT REEF SAFE. He has been in our softy reef for about 3 months.
He did eat one rock clean of some polyps he thought was tasty, can't remember what they were. Since then he has left most everything else alone. He does nip at the clam mantle occasionally.
He had a 60 gallon all to himself for about a year, then we made the decision to put him into the 250. Now he is MUCH happier.
