Hi everyone! My name is Gav I'm from the UK and just about to embark on my first big setup! I currently keep Malawis in six tanks ranging from 5 to 6 foot tanks in a fully insulated shed but have decided to have a go at fresh water Rays after 12 years. My initial plan is to loose the tanks and build an indoor pond of 6x7x2 feet from possibly blocks or a vat if they make one this size and a glass front. This is my first diy attempt as normally biy tanks so any advice would be greatly appreciated
