lets say you add lots of algae eaters as a just in case, lets say you need 10 hermits in your tank to have no visable algae. But you do think that you will upgrade lighting soon and get another fish, so why not get an extra 5 hermits as a just in case.
Now think about it, what do heterotrophs (new science vocabulary, its my nerdy moment) need to survive? They need to consume. If you get 5 extra hermits with no food to feed them, what do you think is going to happen? Its not IF you get more algae later so you should get more hermits, its WHEN you get more algae later you should get more hermits.
