My current set up is a 30ltr tank with some small live plants and 4 odessas 4 roseys 1 golden sucking loach and a flying fox all of which are around the 1 inch or less size, once christmas has come and gone i intend on getting a larger tank but sticking with the same fish just more barbs. any ideas on what size would be good for these types of fish and what sort of layout?
