AUSTRALIA’S most beloved fish is getting a bit more poisonous.

A survey of aquarium owners has found the fish, the Blue Tuna, is becoming more common in the waters of Australia.

The survey by Aquarium Trends found that the Blue Tsunami is now the most common fish found at aquariums in Australia.

It has long been recognised that the freshwater fish is one of the most popular fish in aquariums and many people are still shocked to learn that the fish has become popular in the country.

But a survey of Australian aquarium owners found that they were becoming increasingly aware of the fish.

Aquarium Trends said it was very difficult to tell the difference between a healthy Blue Tsuna and a sickly one.

A spokesperson for Aquarium Brands Australia said it would be an “open secret” for the foreseeable future.

“We’ve seen the growth in the numbers of the Blue and the other blue-finned fish in Australia over the last few years,” she said.

“There are also a number of species that are becoming more widespread, and are not only becoming more abundant but becoming more prevalent.”

In our experience the Blue is the one we see the most, with more than half of all aquarists being Blue-Tuna.

“It is a very healthy fish, which is a great sign for the health of the aquarium industry, as it means there is a lot of competition for water quality.”

Aquatic Trends surveyed more than 2,000 aquarium owners, including aquarist trainers, aquarium owners with children and people who have never been in an aquarium.

A recent survey of the industry found there were more than 200,000 people with aquariums across Australia.
