Is it a problem if the temps stay around 75 during the day and 70 at night ? I have had pacmen before but not in a plastic tank. It is a 5 gal for now with Eco earth water that is easily accessible by him. It's a albino pacman witch i belive is a cornuta correct me if I'm wrong. It's still a small guy about the size of a half dollar. Is there anything that I new to get that I didn't say already? And for a ornate what should I do differently compared to a normal pacman
