Today, I found a bargain tank in a charity shop that I just couldn't refuse! Am thinking of getting either an Emilia, Boehmei or Smithi. It's 30cm wide, 20cm deep and 20cm high. Would this tank be OK for any of these 3? I already have 2 Versicolor slings and would like a terrestrial T that I will get to see sat out rather than a 'pet hole'.
