I’ve had the Sargassum Angler for six months now. It’s quite active and definitely not for beginners. I keep it with larger fish and it hasn’t attacked any of them. The tank is 60 gallons and it’s thriving. Needs a lot of space and a good hiding place though.

This fish is bold and interesting. I expected aggression, and it’s not shy about it. I made sure to have a spacious tank and plenty of rock structures. It’s become a centerpiece in my reef setup. Worth the effort if you’re prepared for its behavior.

It’s aggressive and I had to remove a small shrimp that got too close. I’m not sure if it’s reef-safe in a mixed community. I’d recommend only keeping it with larger, hardy fish.
