How about a personalized terrarium or aquarium with amphibians such as frogs or salamanders? You could also consider a guided amphibian tour or an exclusive behind-the-scenes experience at a local zoo or aquarium that features amphibians. Another idea could be a custom-made amphibian sculpture or painting by a local artist. Or you could take him out on a hiking trip to a nearby park or nature reserve where he can see different amphibians in their natural habitat.
Or you can get him a star map with the date of your anniversary.
