I have a friend that is looking to sell a 150G tank + stand (bottom and top part of stand) for 250 dollars. Everything looks pretty clean besides one crack at the top part of the stand. Only thing I am not 100% sure on yet and waiting on clarification if the glass is tempered or not. Is this a good price and what is the overall outcome of monthly/yearly cost to keep something this size running with about 8-10 fish? Any help will be greatly appreciated.
