To bubble or not to bubble?

I have been considering the reason for bubbles or no-bubbles has more to do with the environment around the foot and column of the bta.

I specifically designed my rockwork around keeping BTA's so have 2 islands with lots of crevices. The two I currently have are in the exact same spot that I put them in when I first got them, at the top of an island with lots of places to plant their foot.
 
Mine are well fed- shredded shrimp every 3 days or so. And all 3 are in the same group of rocks at the top of an island. 2 no bubbles, one bubbles.

I'm not sure what live food would be suitable, other than small live fish which is not something I feel is necessary.



I asked because a) some people give them ghost shrimp and feeder mollies or guppies.
b) I've got one of the tanks where mysids reproduce like crazy and lysmatas release larvae every 8-10 days. The anemone in that tank surely snacks on some of those swayed by water flow.

Horrible pic. But halide is off.

Anyways 2 rainbows always bubbled one split from the other. No feeding other than what they catch floating during broadcast feeding. I have clowns but they show no interest (because of the bubbles) params are 76 degrees 1.024 salinity. Rocks are rough and feet are in cracks.

Lighting is 150watt 14k mh with rb and uv led supplement.

Other. Possible considerations are age, oxygen in water, oral disk size.

I am looking to change over to a mag eventually and would love to experiment with my anemones to solve this once and for all.

Maybe I'll set up 3 10 gallon tanks one t5 one led one halide. All with controllable flow. Slowly change params. Maybe throw in different media to attach to.

Has anyone has a non bubble anemone turn into a bubble anemone with no environment change.

Awesome idea for the experiment!

Also good question ...
But from what I seem to understand most people buy bubbled specimens that loose their bubbles over time.

I had one split, one half bubbled, the other didn't. They shared the same rock, right next to each other. Neither were fed directly.

Did the original one bubble?
Could we assume that a clone doesn't bubble right away?

Because there is a thread from 2008 about a member with 70 clones with bubbles.


Has anyone else observed something similar?

The nem originally didn't have bubbles. It split and the clone bubbled and the mother stayed without bubbles.

It's looking like age might be a trend. Younger splits or younger specimens stay bubbled then as they age they lose the bubble.

One thing I do remember reading once is that maybe the stretchy tentacles are reaching for food? I keep my BTA's very well feed, so possibly feeding is part of the equation.
I've never fed my bta in the couple months I've had it and it bubbles. Weird.

Yep. The tank I got mine from had ai hydra's on pretty low settings and the rbta was doing fine. The tank had hydras on it since its release so it was doing good for several years.



Can you elaborate on low setting?

it was a 35g tank and was running the blues at about 30%, uv about 20% white about 20 as well and the red and green channels were really low, I think about 5%. The bta did climb to the highest place in the tank though so it could have used more light I am sure. It was healthy and stayed in that tank for many years like that though so I know the light can support it with no issues.
