Frequently Asked Questions (FAQs)

 
Is having a fish tank worth it?
Searching for a new fish tank or aquarium for your aquatic friend is exciting! From picking out the perfect one to decorating it and filling it with everything your pet fish needs, it is a fun process.
 
How much does a 100 gallon aquarium cost?
The cost of a 100-gallon fish tank varies depending on where you get it and who makes it. At PetSmart, 100-gallon (380 liters) tanks cost anywhere from $1000-$1700
 
Is it good to have a fish tank at home?
Fish don't bark, meow, play fetch or get the zoomies. While those are great qualities of other pets, the opposite is what makes fish so great. These pets are calming, quiet and serene to watch as they enjoy their environment.
