An expensive hobby

After longing for a saltwater aquarium for over 2 years, I finally took action. I first purchased one 12gallon aquarium from on Thanksgiving weekend but it came dead on arrival – it was leaking because it was damaged during transportation I guess.
So on Tuesday I bought another 25gallon aquarium (with stand) from a UW doctor and set it up. I just realized how expensive it is to have such a hobby – I need live rocks! Each pound of live rock is sold at $7.99 to $15.99 here and I would need at least 70 pounds! I had thought 7-10lbs are enough that I brought one rock back from Hawaii last week but I would still need over 60lbs!
I am anxiously searching over ebay, craigslist, expo for cheaper live rocks… God bless me find some!
