As the title says, my beardie has been acting strange lately and I don't know what it is. He had trouble pooping for a few days but I managed to help him with warm baths. However, every now and then he starts moving insanely fast around his enclosure almost like he is having a seizure or something. This includes fast head bobbing, running into the glass, very dark beard, and even some nervous twitching sometimes. I have been trying to stay on top of his calcium to make sure it's not his bones, so what is happening? Any help would be appreciated!
