This nudibranch is absolutely breathtaking. The purple spots against the yellow body make it a highlight in my 30-gallon tank. It’s peaceful and doesn’t seem to bother other inhabitants. I’ve had it for three months and it’s thriving.

Beautiful and unique. I was cautious about adding it to my reef tank, but it’s been stable for months. The movement is subtle and elegant. I recommend it for experienced aquarists only.

A true visual treat. The cerata are delicate and add a lot of texture. I didn’t expect such a vibrant presence in a small tank. It’s peaceful and doesn’t eat anything I’ve noticed.
