Rock Flower Nem or Majano?

rsucre · 02/02/2016, 04:28 PM

I got these beautiful "rock anemones" (or Majanos?) from a friend. There were 18 of these in a rock and I easily moved them to my rock. After a ReVive dip most of them released from their rock and I moved them with twizers.

They are from 0.5" - 1" in diameter. Skirt/tentacles are relatively short, without bubble tips and burgundy/red color. The oral disk is dark gray (almost black) colored.

I really like them. Somebody suggested they could be Majano anemones, which are considered pests in mixed reef tanks like mine -- specially a 10G nano reef like mine.

But I don't want to jump to conclusions too fast. I want to be sure that they are Majanos before I consider getting rid of them.

Maybe they are Rock anemones or a less invasive variety?

They were most likely wild caught here in Panama, caribbean sea.

Your help is appreciated.

pest or not... they are pretty cool looking

Agree. People rush to say they are Majanos, but I'm not sure about that. From the pics I have seen on the web, Majanos have bubble tips. These ones have no bubbles in their tentacles.

I spent some time reading and looking at Majano pics and I don't think these are Majanos. I see that most pics of Majanos show clearly that they have some bubble tips, which these ones don't have. The polyps on this ones are straight, gradually reducing as they get away from the body. Also the color. I read that most Majanos are brown/green, these are purple-red.

Anyone can point me to a good description of Majanos? I don't want to get rid of these guys without being a little bit more certain.

I'm not positive, but I believe these are tulip anemones. Closely related to Mojanos, but not as invasive. They'll still multiply fairly quickly though.

they sorta look like wartah anemones.

Thanks for your feedback.

I took a look at Waratah anemone (Actinia tenebrosa) and they are from New Zealand and Australia. These ones were most likely wild caught locally (Panama, Caribbean). Also the color is different.

The shape of the tentacles is similar: cone shaped, no bubble tip.

Lots of anemones (or green hairy mushrooms

) can reach plague proportions in your tank - majanos just do it faster than most. Agree that these don't look like the classic majano, but it's an imprecise term anyhow. They may become a plague; or not.
