Thank you all very very much for your replies! That was very helpful in putting a lot of things in perspective and I appreciate the help.
The tank already comes with a shark that is fairly long , it has a hermit crab and some other fish that I do not know for sure but they look beautiful. As the Tank is a High vs Long, I dont know if it neccesarily appears as big in terms of its profile.
The dimensions are 8 ft wide x 6 ft tall x 2 ft deep. I am supposed to pick this tank up from someone over the weekend but was going to ask you guys :
1) What are the key things that one would look at to make sure the tank is in good shape?
2) I believe the filled weight is about 6,500 pounds aproximately. The house i am living in has carpet and vinyl floors . Where would you guys recommend keeping it? What are the potential challenges you foresee with respect to damange to the carpet or vinyl? I believe it will be there for atleast 1 year if not longer.
With regards to live stock, the person I am buying it from told me that I can not do corals as ample light may not reach since it is a high tank. Hence he said he has 'live rock' and gravel and that if i wanted to get stingrays i would need to add some sand on top of the gravel.
From what the owner told me , his maintenance cost was primarily electricity, food and 2 gallons of water a day ( 50c per gallon ) that needed to be replenished due to evaporation ( he said he kept the top open as it allowed the water to stay cooler and replacing the 2 gallons per day were the same as doing a water change).
I dont know if this is true or he said this to make a trade but I thought i would see your thoughts and opinions about whether you think he was being up front and honest with regards to his costs.
Again thank you guys for all the help!
