what the heck is wrong with this BTA

[MacdaRippa]

So this is my Green BTA, been in the tank for about 2 months. Always had great extension and was a perfect until about 2 weeks ago and now will not extend tentacles. Below is my Red BTA, another beautiful specimen on the same rock about 6 inches away and could not be happier.
Any ideas what’s going on with the green one?

chemical warfare?

Not sure on that, both are BTA’s they really should not have issues being in the same area. I thought that initially, but after extensive reading they should be able to co-habitat. Thanks for the input!

Ehh I had problems mixing green with red. One will eventually kill the other, I tried wild caught and tank raised with the same outcome. Lost 2 greens but my reds are doing fine go figure.

+1 chemical warfare, I also wouldnt run nitrates and phosphates at zero, Ive had bad coloration and bleaching in the past using such low nutrients
