Tenecor was once one of the big dogs in the business of specialty, custom and jumbo size acrylic aquariums but it appears that Tenecor is no more. Times are tough and the economy is taking a toll on all types of business and although Tenecor was once a heavy hitter, it seems like a variety of factors have forced the company to close its doors, shutter its website and turn off the phones. Over the last few years we’ve heard less and less about the once iconic acrylic tank manufacturer and we’ve heard that they’ve been struggling to supply products all year. At first it was unclear what was up with Tenecor but a statement on their website reveals that they are no longer in business. Unfortunately a few customers have been left hanging out to dry with undelivered goods and we hope that they eventually get taken care of in some shape or form.
