OUR REVIEWS

Great store and staff, every time I've gone in for products or advice I have been helped promptly. Everyone there is very knowledgeable and if they don't know they go out of their way to find out.
I've recently bought a complete set up for Axolotls (my boys love Minecraft 😁) not knowing a thing about them the staff helped me along the way getting things up an running, making sure the water was right and that all the plants, fish and equipment was what I needed.
The axies are healthy and active and my boys are wrapped with their new pets.

This has been my default aquarium for a bit over a year now, the staff are always up for a good chat and genuinely care, every person who works here knows what they are talking about and proves it when they don't 100% know something they will always say so.
If you are in the area always make sure to stop by

Incredible experience! Josh helped us pick everything for our tank, he provided us with heaps of information and was so amazing we wanted to buy everything. Can't wait to set up our tank at home.

Nautilus Aquariums
is the place for the best advice, products and service. The owner’s (Scott) many years of knowledge and experience in producing the “Aqua Pics” range of products has resulted in the best products one can buy for their aquarium or pond needs. I’ve been using Aqua Pics for many, many years and can vouch for the quality of the products. Aqua Pics uses the highest level - “pharmaceutical quality” ingredients, which means optimal water quality, healthier and happier, and longer living fish. You’ll find his products - “Aqua Pics”, in all many shops and if you can’t don’t bother wasting your hard earned money on anything else. Scott’s advice and customer service is exceptional. I often find his advice saves me money. This level of service is often lacking in other shops. That is why I always go back to Scott at Nautilus Aquarium and Pet Supplies and it’s where you’ll get the BEST advice, products and service too.

This is my favourite aquarium. Scott knows more about fish than anyone I have ever met and Joey the manager is a brilliant aquascaper - it is worth calling in just to see his aquascapes. The two new staff members Samantha and V are lovely.
