The fact that you can have your own t-shirts printed for super cheap nowadays is totally cursed knowledge for someone like me. Now to commission someone for a proper design... 🦐

My new Zoanthid coral came with an Asterina starfish. This is why you quarantine your corals folks! Well, except if you're me—I hope to adopt a pair of harlequin shrimp soon, which exclusively eat starfish. Go forth and multiply, little Asterina.

Completely forgot to share the latest issue of PFK Magazine! My article "Demon Damselfish" goes into whether these small, cute, and astoundingly angry fish are suitable for your reef #aquarium.

Went into the pet store for some RO/DI water and they had a nice Tubipora musica frag for a tenner. Don't mind if I do! 🪸 Now to get a light that actually makes this baby pop... #aquarium #reef #coral #reefkeeping

Google Photos reminder: exactly a year ago I went #diving in my home country for the first time. So different and magical! This was at Grevelingenmeer.

My fish is front and center on UltraMarine's new cover! In this edition, I talk about meeting the masked butterflyfish Chaetodon semilarvatus in the wild—and whether this yellow stunner is right for your reef tank.

Here are two Tetraodontidae I met in the wild in Thailand: a dogface puffer, Tetraodon nigropunctatus missing an eye (but clearly thriving!), and a spotted porcupinefish, Diodon hystrix.

🐡 My latest article for Tropical Fish Hobbyist is out in their July/August edition! This feature discusses the wonderful Tetraodontidae—not just how to keep them in your saltwater tank, but also lots about their natural ecology, taxonomy, and more.
