Hi, I'm new to this. We have I believe a female Cuban rock iguana. She is about 3 years old. We had her in a 150 gallon tank and she has done well. My husband had good light humidity and she has the bark in there. She eats greens daily sometimes grapes carrots and apples. We were searching and searching for a bigger affordable cage for her. We found one. Like 7 feet tall, 8 feet long and about 4 feet deep. But it came with an iguana who needed a home. He is a male rino iguana. About 3 years old. They were doing ok together. Our rock iguana (roxy) is not afraid of Ziggs. They hang out together. But roxy is hiding under her cave the majority of the day and not eating any of the greens. Only a few grapes. This has been going on for about a week. I'm VERY worried about her! Help please... Any advise is greatly appreciated.
