Yeah i like a more real looking substrate. I have been thinking of going bio on Pat PVC. Pat loved the Reptichips and was digging in it the first few days. I dont think he ever saw the stuff before lol. It was like i had a little yellow boa for a few days. He doesnt really dig in it any more but he does sit on it a lot at night along with playing scuba steve in his big water bowl on the floor lol. Guess a few people i talked to said males do that a lot where as females usually just maybe move from one perch to another or get a drink.
