Making a splash with Zac’s tank tales

Dive into the vibrant underwater world of the Mornington Peninsula’s very own teenage coral reef maestro, Zac Curtis. With a fervent curiosity for reef ecology and a knack for underwater chemistry, Zac’s journey into the life aquatic has been quite the adventure.

Starting with a modest freshwater tank, Zac soon realised that the colourful world of coral reefs was where the real magic happened. He’s now the proud owner of two tanks: a large 200-litre and a small 52-litre set-up. These underwater wonderlands are home to a bustling community of tropical fish and coral, creating a mesmerising scene straight out of a Pixar movie.

For Zac, the joy of tending to his tanks extends far beyond a hobby; it’s a therapeutic escape into a world of tranquillity and wonder. As he watches the graceful dance of soft coral and the playful antics of his finned friends, he finds solace in the rhythmic ebb and flow of underwater life.

His favourite fish is the coral beauty angelfish, which follows him around the tank and eats out of his hand, and his favourite coral is the colourful and varied zoanthids.

But with the beauty comes responsibility and dedication. Zac must meticulously maintain stable water conditions, monitoring levels of nitrates, phosphates and ammonia. Weekly water tests and regular 20 per cent changes ensure his aquatic inhabitants thrive in a healthy, balanced environment.

Despite Zac’s diligent care, he’s had his share of fishy escapades, like the time one adventurous clownfish decided to pull a Finding Nemo and make a break for it through the overflow. Other unexpected mishaps include the unfortunate fate of one fish being eaten by a voracious coral banded shrimp, and another being bullied by a larger tank mate.

Yet amid the trials, Zac’s tanks are thriving. He’s learnt the ins and outs of coral growth – that some prefer water flow and light more than others – and moves it around to different spots in the tank to help it flourish. He’s also invested in a generator to safeguard them during unforeseen power outages, as tanks can only remain idle for a short time before permanent damage is done.

Feeding time is a spectacle in itself, with fish eagerly gobbling up algae and mysis shrimp like it’s a Michelin Star meal, while the coral are treated to a buffet of phytoplankton (microscopic plant-like organisms) and copepods (small crustaceans).

Zac’s top tips for aspiring tank enthusiasts? Take it slow and steady; research at your local aquarium rather than online; start with a second-hand tank but invest in new equipment; don’t rush into adding new fish or coral too quickly; and be aware that it can be an expensive hobby.

As Zac continues to navigate the watery world of his coral reef tanks, each day brings new discoveries, challenges, and many moments of joy.
