aquaponics is one of the best concepts to be used in betta fish tank
The fish poo andpee and all that waste-water gets broken down by beneficial bacteria into nutrients.
The waste-water from the fish is then pumped up & upcycled as an awesome organic fertilizer for the plants. The plants take up the nutrients and, at the same time, clean the water which then falls back down for the fish.
There is no soil – the plants are growing just on rocks and there’s no need for any artificial fertilizers – it’s all organic!
The minimum betta fish tank size is at least 2.5 gallons. Betta tanks are available through traditional pet stores that are far too small to house a betta. Betta fish should NOT be kept in jars, bowls, cups, or small aquariums, regardless of whether or not they can survive. You could keep a dog alive in a tiny crate for its whole life, but that doesn’t make it right.
