Thanks for all the responses. Well he has them together since yesterday. They SEEM to be fine. They are even haning out fairly close. The Senegal crawled right over the Fisher. I just checked on them but I'm going to speak to my husband this evening about their housing situation. I am even wondering IF the potential problem might be sexual maturity or mating season which might kick in aggresive behavior. How does the mating season or maturity work with Chams? Is it by age or particular season? Both? We had the Fisher treated for parasites by the vet. We used to have the Senegal in a cage with fake and live plants. The drainage from plants and mistings went to a bucket beneath the cage. We misted once or twice daily and used a dripper and day/night lighting. Now we have a reptarium that includes everything. What about live plants? Are they a neccessity even with proper set ups? My husband's "fever" is worse than just Chams. We have a Toy Poodle, Yorkie, Macaw, Cockatiel, 3 Sugar Gliders, 2 Hedge Hogs, 2 four foot Iguanas, Boa, Corn snake, Beardie, a few arachnids and these 2 Chams. The set ups are nice but I am the one stressed because I am constantly concerned of their needs. My husband is a procrtastinator and I'm a doer so a lot of the work falls on me. UGH! THANKS FOR ALL THE ADVICE! I just hope I can get my hubby to take it into consideration. I warned him he would probably need another reptaium. I warn him of impulse and pet store owner's advice all the time. He hears what he wants to hear! Ugh!
