3 RBTA, 3 different postures.

[guruduck]

Hi
I have 3 RBTAs in my tank. The biggest one is about 6 inches, the medium one is 3 inches and the smallest one is 2.5 inches. The medium one and smallest one were actually one piece 3 months ago. It splited.

One thing very strange is that, since I upgraded to LED lights, they all have different behaviors. The biggest one has a very big disc but shrinking tentacles. Weak, thin and curly. Some times the mouth is little bit open. The medium one has a long stem and the smallest one is short in statue and has a few bubble tips. In other words, the smallest one is the healthiest one, right?

They don't move often. So I assume the light and current flow is okay. They all receive the same kind of LED light (70W cool white + 70W arctic blue) 12" above them .

If the biggest one is not receiving enough light, it should have moved higher. But no, it stays there forever.

Please see pictures and suggest what is going on.
Thanks

Sounds like they are acclimating to the new
Light IMO. I have 9 bta's in my 46 and even after a year the biggest of my bta's are lower in my tank while the smallest are up high. Your biggest needs fed IMO. I would do that every couple of days to once a week. My rainbow bta is doing that as is it's clone is also. Feeding has helped.

I would definitely suggest, that they are adjusting to the new light. Acclimation, should be the same as you would if you were changing out bulbs in your previous fixture. I have an array various type's of anemone's, under 2 x 250w Tao Tronic LED's.
