How did this happen?

[PGUY1]

I haven't added anything to my 18 month ol tank in at least six months except snails. I have been trying to figure out the white spots on my monti cap that started last week. Two nights ago I found monti eating nudis. What? How did this happen? It is big, three or four layers deep and always healthy. I don't get it.

Could be the snails. They come with hitchhikers. Anything live can bring hitchhikers.

what will they eat if he had nothing in the tank but snails will the monti eating nudis eat only the monti's or can they survive eating something else? like aefw i have been told will starve out if i take all the sps out and leave the tank without any for 2 months or so . that eventually they will starve out is this the same with nudi's?
