Hi there, I have a 42g, 32in long 14in width 12 height. I currently have got 12 zebra danios and 7 Cherry Barbs. I am planning on future stocking. Here's my plan: 12 X Zebra Danios (2 red, 10 Blue) 7 X Cherry Barbs 8 X Cardinal or Harlequin (or both?) 5 X Pristella Tetras 1 X Dwarf Gourami 1 X Ram Cichlid Base on Aqadvisor I am kinda close to over-stocking? I would like to add a Ram too. But not sure about the compatibility esp with Gourami. or even get both Cardinal AND Harlequin. I want colors in the tank. I already have cherries and red zebras. So I would avoid more red. Any suggestions? Thanks!
