are there any live foods that reproduce too fast, grow too big or hide too well so that my rainbow shines can't eat all of them. (or at least live foods that last a long time)
i was thinking to add blackworms and hope they'll hide in the substrate, keeping both the substrate loose and serving as a snack.
asellus aquaticus, are already in my tank (added these 1-2 weeks before the fish)
if i manage to find them somewhere i'll add scuds as well.
preferably species that will live off of algea, dead plant matter, fish waste. (as that saves me a little work with cleaning)
