...affect them? i have a single blue beta fish in a glass bowl and want to place him in the shelf but the shelf is dark as in there is hardly any light around it. is placing my fish there going to be harmfull to it if it dosent have light?
does it matter?
Having no light will not harm your fish. Having him in a bowl will. Bettas need a minimum of 2.5 gallons. They must have a heater and filters are also great to have. Since they're tropical fish their water should remain at 78-82 degrees.
