Ive hardly ever posted (more of a lurker) BUT ive got a question.
when i first got my turtles i bought them a few bags of 'river rocks' for substrate, but theyre starting to outgrow them and with the ammount of scavengeing they do im beginging to worry they might end up swallowing some. SO, i went to the beach and collected a bunch of beach rocks. My question is, how (or should) i sterilize them ? Any help would be great.
