fish tank equipment

  1. Betta Fish Care
    Hi, I was wondering what kind of equipment will be suitable for my future 20-Gallon Community Tank. The fishes I plan for my tank are: 1 Male Betta, 3-4 Guppies, 4 Cories and 8 Neon Tetras. So, what are the equipments needed? Are there certain types of heater, filter, lighting, etc that'll help...
