I have been keeping aquariums for more than 30 years .... I have had as many as 8 aquariums up and running running at a time ... Mostly freshwater fish but I have had a coral tank and plan to do another in the future... here are some pics of my current aquarium set up. It's a 90 gallon Bucktooth Tetra tank and a 5 gallon tank with a few Ember tetras
