What species of fish that can reproduce using the rotifer B. plicatilis as food?
Most of the common species (clownfish, gobies, dotty backs, grammas, etc.) If it's a demersal spawner(lays eggs, doesn't release them into the water column), chances are relatively high that the larva will be able to eat B. plicatilis for a first food, but you have to remember that the larva can't subsist off of rotifers for forever.
Already the fish that spawn in the water column, the rotifer B. rotundiformis would be, in general?
I would suggest Wittenrich's Complete Illustrated Guide to Marine Aquarium fish. What do you mean by power range? I am having trouble reading the text, and am very confused about this post. Are you asking if pelagic spawners' larvae would eat S strain rotifers?
