I don't use suction cups on mine anymore. I zip tie them to small rocks to keep them in place.
What i like to do with all the ornaments and etc. that are gonna in contact with aquarium water is to soak them in hot (just hot tap water) with high dose of salt to sterilize them! Just a precaution thing
