Did anyone ever find a definitive answer about the BTA tips --straight or bubbles?

[Angel*Fish]

I've been away for a while. Do we know now? Is it the current? Wave makers? Water quality? Lighting? The bubble fairy?

 

[Christian_S]

that's a good question

think probably is a flow cause when I always go and see it a the LFS, they always have it where is not so much flow and the anemones looks amazing but when your buy one and you put it a your tank with a lot of crazy flow around, anemone always straights the tips

well this is always my case

 

[garygb]

No, still no definitive answer. Some say water flow, some say hungry vs. sated, some say bright vs. less bright light, some say fish vs. no fish. I have both GBTA and RBTAs under t-5s that are always bubbled. The same clones under MH seldom bubble. I think it may be light intensity and perhaps Kelvin combined with other factors like water flow. Someone really should make this their marine biology dissertation topic.

 

[BonsaiNut]

No answer. In the wild, in a colony of clones, all located in the same area, some anemones will have bubbles, some not.

I lean towards lighting and zooxanthellae population, personally, but I have absolutely no evidence to back it up.

Here, I'll stir the pot a little.

This is mine midday:

again at 9ish:

and again at 10:

I have had this RBTA for about 3 weeks. The tank is over a year old and stable with a GBTA and sebae in it, both doing well. The GBTA stays half bubbled almost all the time regardless. I have the tank on a 15 hour light cycle and the RBTA does this almost everyday between 1 and 5 hours before lights out, sometimes earlier. I don't dose anything, I don't do many water changes, I feed twice a week. Water stays clean due to a good skimmer and a great biofilter.

I would have to say it has something to do with light intensity.
At night, mine shrinks and there are no bubbles, it is in rest mode for a couple of hours and then gets the bubbles back.

Once actinics come on, it expands with bubbles swaying.
Once the full lighting comes on, 6x39w t5 my rbta will most most of it's bubble tips but not all.

Mine has placed itsself halfway down my tank on a maxima shell and has grown from a 1.5 inch anemone in July to 3 inches now.

 

[Randy Holmes-Farley]

I agree with lighting being important somehow.

At one point I had many clones in the same tank, and only those in the brightest light were bubble tipped.

I recently posted a research paper on how coralimorphs change physical characteristics in response to UVR and zooxanthellae populations (which in turn affected internal levels of dissolved oxygen and production of free radicals). As soon as I saw that some coralimorphs bubble up their tentacles in response to increased UVR, I immediately began to wonder about BTA's.

Mine has been in several places through out my tank. Bubble tips/no bubble tips. Who knows? I gave up trying to figure it out. I just turned the halide on and there are no bubbles. I'll report back later with my findings. :lol:

add this to the pot ...

add this to the pot ...

I've had my RBTA for about 6-8 months. It has had bubble tips and not. I recently fed it a whole silverside ..now it has bubble tips on 1 side - toward the light and in the return from a Mag 9.5 ...so who knows:lolspin:
