How to find a good fish aquarium in Perth:

1. Online Reviews: Check sites like Google Reviews, Yelp, or Facebook for reviews from other customers. Look for comments about the quality of the fish, the variety of species, the helpfulness of staff, and the cleanliness of the store.

2. Local Forums: Search for local forums or Facebook groups dedicated to aquariums or tropical fish in Perth. Ask for recommendations from other hobbyists.

3. Word of Mouth: Ask friends, family, or colleagues who keep tropical fish if they have any recommendations.

4. Visit in Person: Once you have a few options in mind, visit the stores in person. Pay attention to the overall atmosphere, the health of the fish, and the knowledge of the staff.

Remember: It is important to choose a reputable store that prioritizes the health and welfare of their fish. Look for a store that has clean tanks, healthy-looking fish, and knowledgeable staff who can answer your questions.
