Hello im a newbe to both the forum and to fish keeping. I have two 30ltr freshwater cold tanks and im looking to up grade to a 100ltr or there abouts, what tank or tank system would you recomend? I have some redfire or Rathbuns bloodfin Tetra, some Dwarf Golden Barbs in one tank and some platies and some white and gold Cloud Mountain Minows in the other with real plants and bog wood. There are also redcherry shrimp in the tetra tank and Amarno shrimp in the platie tank plus snails... we want to combine in to one tank. Thanks in advance for any advice...
