It does barely attach to the sand/shells I have around it were it's verrucae are but the base doesn't attach to anything.
When I bought it it was completely white but now it is starting to get color so it is getting better. It got dislodged today (water flow, not on it's own accord) and I replaced it and moved a rock to a different angle to keep it in place. I looked at it about an hour after I replaced it and it looks like it has moved in and settled in between the two rocks I had it and has opened up to it's max. So now I'm guessing it has finally attached.
The one thing I am kinda worried about is it is not eating. The food sticks to the tentacles but it doesn't take it in. I'm shot it with mysis, given it squid soaked in vitamins, and shrimp. It ate the shrimp once but nothing after that. The color is coming back so I'm not so worried yet. My lfs
is going to get some silversides in next week so I hope that works.
The gbta (I've had for over a year) takes in any food I give it and swallows it in under 20 seconds easy. And the new bta I have is taking in food pretty fast also, but it is still bleached. It has gone from total white to white tentacles but the brown/tan has come back in the two weeks I've had it and it's moved about 1'' from were I first put it in so I'm happy that one is doing good.
I found some good info on quarantine procedures for anemones- doxycycline dips that have been very useful in successfully keeping newly introduced and sick carpets and H. magnifica that is worth a shot if a last resort.
