Thanks for the comment Onion. They are around 4" now and are in a 125 gallon tank. They are still a little skittish but are doing much better. After Joe's tank cleaning advice, the tank is in perfect Nh3/2 and Ph levels, it just took some 20% water changes.
I have owned exotics all my life, 4 ferrets, 1 parrots and a female king cobra at the moment and this is my first fish experiance other than "normal fish".
Thanks again for all of your help
