[firehazard]

im trying to get info on where people put their fish tanks.. and im not talkin about their living room... im talkin about the unique places people find to build a custom fish tank... after seeing people macking massive tanks with fiber glass.. i want to make one too.. or should i say try... so basically does anyone knows or built any thing out of the ordinary... it doesnt have to be a full blown reef... thank you..
