Notes

Siamese Dwarf Rasboras are another nano fish species that prefer softer water conditions.  They should be kept in large groups to feel comfortable and safe, so aim for more than 8 if possible.  Although they can get by in a 5 gallon tank, 10 gallons is recommended for a good shoal effect.  Keep water parameters stable as they're sensitive to fluctuations and nitrates.
