What Does Shinehorn Eat After Taming

[Hengard117]

Exactly what the title says. I checked the wiki,but I don't know if the taming foods are all it eats. I have it on the island (Cross Aberration Mod),so even though I can craft Plant Species Z seeds,I am wondering if there is an easier food source for it.

Berries. Same for when breeding. Not sure if they might eat various varieties of shrooms too.
