My 1 year old male panther is currently in a 18" x 18" x 36" aliminium screen cage. He obviously need more space and I was planning to build my own but I've had no luck finding materials. Are flexariums good? I'm hoping to buy the biggest (260 gallon). I'm told they are ugly (they don't look it in the photos
) but I don't really care - it's for his benefit not mine. Or is there something better than flexariums? As I have been told it is hard to maintain humidity and temp in these.
