Hi
Well deah that tank is huge for paros… we know from some reports that such an idea can work but not necessarily with breeding. One of the points that seem important to me is the idea of keeping other species with the paros. This I would not advise you to do or at least not in the beginning until you have made experiences with breeding and more importantly raising paros. Other fish such as boraras are very active in hunting food. Paros are not. Sometimes the artemia or whatever you might want to feed seem like they had to swim into their mouth before they will catch it. Of course there is a certain hunting instinct but the smaller and quicker fish are likely to eat everything before the paros even start feeding.
Nevertheless this is a beautiful tank!
