4 inch for $65 is a damm good price for MBU's. The are hard to find puffers in the hobby because they grow too large for LFS to keep one around especially aggressive behavior. If i have a 100 gal tank i would buy it but i already have one too many tanks in the house the lady wouldnt appreciate too much..heh.
Hope you guys will get the Irrubesco soon..i will definately buy a few. Especially juveniles!!! Please keep me posted on your PUffer stock!!!
