VERY FIRST TANK 30 BREEDER. I still have it in my storage. I have been trying to find them but I think the 30 breeder has been discontinued. I love the size of it though will never get rid of it. I have 2 my first tank was one as a display and the other was under it with a couple peices of plastic sheet siliconed in place worked out ok for a really cheap start, basically free...
