Flamboyant Cuttlefish are semi-aggressive and should be kept in species-only tanks. They are not reef safe. The species is extremely toxic, and the toxins are comparable to those found in tetrodotoxin. Handling should only be done by expert aquarists or individuals with extensive experience.

Carol Skinner –
I have kept this fish for six months in a 50-gallon tank. It’s visually striking with vibrant colors, but it’s not for beginners. I had to learn a lot about handling and tank maintenance due to its toxicity. It’s a great addition to an expert aquarium, but requires careful attention.
Molly Davidson –
The colors are absolutely stunning. I’ve seen it change shades throughout the day. I keep it alone in a large tank and monitor water parameters closely. It’s not aggressive, but I do avoid keeping it with any invertebrates or corals.

I tried to keep it as a beginner project, but the toxicity warnings and care requirements were too much. I ended up removing it after a few weeks. It’s clearly not suitable for inexperienced aquarists.
