As Pat said, saying it's a "Tremper" means nothing about the geckos health now. Hundreds of people have bought geckos from the original tremper and bred them. The reason some morphs have "tremper" infront is because he actually made those morphs. Like the Tremper Giant, he was the first one to create it. Just because the leo is a tremper doesn't mean it's actually from trempers private breeding stock, which means you can get a sickly "tremper" even though Ron Tremper only sells healthy geckos.
