Gday guys, Im looking to sell my parents fish tanks but I have no idea how much theyre worth. Just wondering if theres any fishtank connoisseurs out there who could give me a hand. Theyre all in very good condition but need a bit of a clean. Theres three tanks and they all have stands and pumps and hoses and heaters and stuff. They were for tropical fish. I'll get some sizes for them when theres more light tomorrow. 1. This one has some rock stuff at the top and the water flows through it which I presume is a filter of some sort. Approximately 3 times larger than the 2nd fishtank 2. 3. They will be up for sale once I find out how much theyre worth. Thanks!
