FAQ about Fish

Can fish live with other pets in the house?

Yes, but make sure the aquarium is placed securely out of reach of curious cats or dogs, and supervise children around the tank to prevent accidents.

How do we keep our fish tank clean?

Change about 20% of the water weekly, use a gravel vacuum to remove waste, and regularly check filter function to keep the tank clean and healthy.

How often should we feed our pet fish?

Most fish should be fed once or twice a day, only as much as they can eat in 2-3 minutes to prevent uneaten food from polluting the tank.

What do we need to set up a fish tank at home?

You’ll need a suitable aquarium, water conditioner, a filter, a heater (for tropical fish), gravel, decorations, and water testing kits.

What type of fish is best for beginners and families?

Hardy fish like guppies, platies, or goldfish are great for beginners and families because they are easy to care for and adapt well to a new aquarium.
