Haddoni and rock

[falcondob]

A LFS in my region has what they are calling a haddoni for sale. It came from a local reef tank and had been there a year. They have had it for year and a half. So, it sounds like a pretty hardy specimen.

My question is, that the nem is, and has been, attached to a rock for that entire time. I though haddoni would not attach to rock. Is that true or are there exceptions?

He sent me a picture and (to my novice eye) it appears to be a haddoni.

IME with Haddonis (( been keeping them for 10 years )) they have all been in/on the sandbed. However, they are right at the sand/rock interface and will sometimes have their foot attached to the underside of a rock -- which can only been seen when attempting to move it.

If it is a Haddoni, and attached to the top of a rock I would say that that is very uncommon and could be cause by not enough light, not a deep enough (( or any )) sandbed, or it is an oddball.

+1 on above post. If the rock was beneath the sand or adjacent to the sand it might have been attached and been transported that way for easier removal. Also, the nem could have come from a BB tank. I did "rescue" one a few years back that did well in my BB tank.

A cell phone pic would make it easier to ID.

Agree with all the above

Also, as people have previously mentioned, these anemones are large animals and are surprisingly strong. In a BB tank, they can easily squeeze beneath/between large rocks, and possibly bring down your reef structure, including tumbling rocks into your glass-sided tank. In a sand bed, once established, they do not tend to move for years at a time. However if they are not happy they will wander your tank and cause all sorts of havoc, including going into your overflow, embracing a powerhead, stinging all your other sessile inverts, etc.
