It’s getting hot in here!!! 🔥🔥🔥🔥

60+ heaters, one very important job.

Our team has been busy fitting Aquael Ultra Heater D/N 200s throughout our bay tanks to help maintain stable temperatures across the store.

Because keeping our livestock comfortable and healthy is always a priority, even if things are getting a little heated behind the scenes. 🐟❤️

Meet the Collector Urchin!

Looking for a unique addition to your reef? Collector Urchins are fascinating little clean-up crew members known for their quirky habit of picking up and carrying bits of rock, rubble, algae and even shells on their backs!

They’re not just interesting to watch, they’re also great grazers, helping keep algae under control as they move around your rockwork.

Come check out our current Collector Urchins in store! 🪸
