I have had my dendro forever, and he was always happy, but now he seems to be upset at something. I recently upgraded my lights from PC to LED. I think the LED may have been to bright for him. And he started to recede, but right in the middle of him. His skin that coats the skeleton just got a hole. Hmmmm.... So i moved him to a lower light setting. And gave him a little more flow. No change. It cant be water chemistry casue these things are hardy, and my birdsnest and other more difficult ones are doing just fine. Help!!!
Should i completely put him in a different tank and see if that helps??
