hello everyone. i have been thinking about upgrading to a larger tank since my fish will soon outgrow my 2 tanks. the problem is that both grow large, and neither tank will coexist together. So i had this idea to build a pond that is 6x5x2 and divide it into 2 sections so that it would be 3x5x2. This would be enough room for all the fish to grow into. I would like to build it so that it is viewable from all sides. I do not have any experience with building tanks, so any help at all is appreciated. Thank you!!
