Ya, never any guarantees with BTA, but I've had one in my tank for close to 4 years & it has moved, but never very far. Early in the game it moved behind, almost under the rock I placed it on & after about a month I had to turn the rock, otherwise it would have wasted away due to lack of light. That was a pain, since the rock was supporting others & most everyone knows what happens when you start shifting one rock....

It has split a number of times & has always hosted a Maroon, first a single, now a mated pair. The original BTA & one clone are still on the same rock, I've sold or traded at least three other clones. Things that will help keep them in place IME are, as mentioned already, a slight depression or hole for their foot and probably also a clownfish partner. The original BTA I have shifted again just recently, not sure why but possibly due to some nudging by my Maroon female. The pair has been spawning for some time now & quite often will encourage the nem to make room for the spot they select to put down the clutch of eggs. Just as I was starting to get a little nervous about where it might end up, it stopped shifting, not all that far from the spot it's been anchored on for a couple of years. I have two VorTech pumps & they would no doubt make short work of a wandering nem that got too close.

That really scare me. I would prefer one that stay in the sand and does not require too much high light. Maybe a hiteri? That way I would not be afraid of it wandering in the pump.

Today I had to put a net over my duncan...it does not look too good today and it is all shriveled. Usualy it is fully inflated at that time of the day with the light on.

It was ok with the male because he was more gentle but the female is a freaking bully!

As soon as I put the net over the duncan, the make went to try and coach the female to adopt my other duncan, wich I also like but has shorter tentacles and it is even more anoy then the other.

sign...no way around getting an anemone or getting rid of the clownfish. If only I could find an artificial anemone :)

I bought an anemone
 

I got an anemone but now if the fish are going to go in it is another story. It's huge! It did not look so big at the store but in my 75 gallons it's a monster, about 10" across. I think it's the long tentacles, not sure, but it is one of the type that stay in the sand and are supposed to host clownfish.

Now beside the photo tric, any way to make the clownfish adopt it?

Time and patience.

If you discourage it away from your duncan it'll go looking for another home, so it make host the nem sooner. But don't stress out your fish! Just give it some time.

You must really like your clowns... When ever I had the issue of a fish pestering corals I've always removed the fish. I don't have alot of patience for unruly fish...:biggrin:

I try to accomodate every living thing in my aquarium and yes I do love my clownfish :)

But the anemone is nice now that it has settle properly...it's big though :)

The clown have started to go near the anemone tentacles. The male touch it sometimes but he does not really rub its full body yet, but I think it's will be just a matter of day. I put a net over the duncan and it is recovering. Today it looked much better, although the net is preventing it from fully inflating. That's still better than having a clow pestering it.

I am going to wait and see but I think there is good hope now that he's showing interest.

Can it go the other way around? Can a coral kill a clownfish? Had a baby ocllaris (1") in a tank with a torch coral. One morning the clown is gone. Never did find the body, not on the floor or anywhere else. I'm thinking maybe the torch got hungry?

Had an elephant ear-type, very large mushroom coral close up over my eating-frzn mysis mandarin goby about 8 years ago. One minute the goby was sitting on the coral, then next the coral was closed over the "stupid" fish, (I thought it was smart enough to swim away), and a few minutes later, when I looked again, the coral was slowly opening up with the goby dead in the middle. Mandarin gobies are poisonous I believe, so the coral didn't "eat" and digest it, but it certainly killed it.

no, I don't think so. your clownfish probably dies and the cleaning crew ate it.

My clownfish went into the frogspawn and decided it was not a pleasant experience and did not return but it was fine.

I even doubt a torch can sawllow a whole fish.

What do you mean a few minutes later?? you did not pull the fish out?!!??
