We have 2 male beardies. They have lived together in a 50 gal terrarium since we took them both in. They are about 6 and 8 months old. Recently the older one has being acting dominant and I found a bite mark on the smaller one so we put a divider between them in the terrarium. They both have adequate heat and light, but they have both been angry since we separated them. One hasn't eaten in the past 3 days and the other has barely eaten, and refuses water. Any advice?
