Need your advice, what kind of pellets/Flakes do you feed your guppies?
Do you concentrate on Hikari brand or others?.
Is it necessary to cover the tank with dark background?
I have a tank 1 feet x 1 feet x 1 feet custom made and still bare/clear glass.
What type of filter you use? Which one is better, filter box with cotton wool inside or sponge filter.

I used filter box but my tank become slimy very fast. Do you have a way to settle it.

Please pm me your Blue Grass price. Really nice. Is it s train you get from Japan?
