I upgraded the 10 gallon to a 20, for the sake of more plants. Now I am told I need more fish! (this is a hard concept for me as I am neurotic about not overcrowding ) The fish list now includes 3 german rams, 2 cory cats, 5 neon tetra, 5 glolight tetra, a CAE and a betta. Miscellaneous inhabitants are a dozen ghost shrimp and 2 (I hope) apple snails.
