I found this tank on craigslist. I'm told it's a 70gal but its got this odd cavity/column in the back-center. I guess the filter goes there..? Any ideas?
They used it as a terrarium (hence the white sticky stuff but I plan on filling it with H2O). Has anyone seen this type of setup before? Where do I get filters and stuff that work with this kind of tank? That center column is water tight and does not fill with water so I assume that some kind of filter or something goes in there but I'm a newbie and have no idea... Help!
