I've got an Rose Bubble Tip Anemone and it has long and straight tentacles, they only had the "bulb" shape at the minute I put the invert into my tank. Do you know what could cause it? Is it a bad health indication or even worse? The clown loves it since it was introduced to the anemone and they have been living a beautiful relationship!
My water has "normal" parameters with temp at 79-81 and salt at 1.022-23
Mine would only bubble once in awhile than again I got her bleached so it took about a year for her to fully recover. Than she would bubble when she wanted to and I had the right lights for her too. I had Radion Pros 4 of them for my 280 that my uncle bought me when my T5HOs finally died and could not get them to work again.
It is definitely odd...even odder that no one has studied it. But I have seen two anemone side by side, literally a split from the other, where one bubbled and the other didn't. Strange and really neat all at the same time.
