Brought home a nice big yuma a couple weeks ago. It adjusted very well, placed low and in indirect light. Last week I upgraded my lights to LEDs and the yuma looks to be falling apart. It started out by looking like it was vomitting, now there are small pieces falling off its outside tenticles. What is the deal? The rest of my tank is thriving in the new lights, but this yuma isnt. I also brought home a different yuma the same day as my other one and it wont open up any more. My parameters are good and I do regular water changes, Whats the deal? Ill try to get some good pics. Thanks
