Hi, As a newby to tropical fish tanks I have done loads of reading and found some good advice. One thing that still elludes me however is the correct stocking level for my new Juwel Rio 180 litres . There are a number of different guides but nothing definitive. I have tried AqAdvisor which says I would be overstocked whilst others use a ratio of 1.2 x litres which would put me easily under. My current set up includes a number of live plants including Amazon sword and Cabomba with a few pieces of bog wood for decoration and the intention is to have the following: 5 Zebra Danios (already in tank) 4 Sunset Platies (already in tank) 5 Green Glass Cobra Guppies 2 (or more if can) Opaline Gourami 2 Diamond Gold Angelfish 2 Bristlenose catfish Does this make for a good combination and would they all fit in a tank of this size?
