How many fish are lucky in an aquarium?

As per Vastu, you should keep nine fish within the tank to ensure a positive energy flow.

Can you keep any plants within your aquarium?

Yes. Plants that can grow in water, such as lucky bamboo and money plants, are best for aquariums. So you can keep these plants in your beta tank without completely submerging them in the water. Make sure that the roots are underwater and the leaves remain outside. Most of these plants absorb nutrients from the water, and you might also choose to add some liquid fertilizer for optimal plant growth.

Should you consider placing a fish tank with children around?

Ensure that the stand on which you keep the fish tank is solid and durable so it does not tip over easily.

However, avoiding glass aquariums and choosing an acrylic fish tank is best if you have toddlers at home.

Should the water within the tank need to be changed each day?

No, this will kill your fish. Never change the water in your aquarium entirely. Make sure you change twenty percent water only per week. If you have a filtration system, you must change thirty to fifty percent water in a month.

Do you know why you shouldn’t change the water frequently?

Because the microorganisms within the water help the fish survive, changing water entirely will wash off these microorganisms that might be fatal for your fish.

Can we keep aquariums close to the TV?

As per Vastu, you must not keep a fish tank near or on top of any tv or speakers. However, if you think you have no other option to place your aquarium, then the best option would be to keep it safe so that the fish do not get disturbed within the aquarium.
