Don't have a dwarf puffer yet - just ordered a Spec V to set up though!
Will have plenty of snails from the main tank for food, but was also wondering if dwarf puffers like scuds? I fight them all the time in my shrimp tank at work, could easily put them in the Spec while it is cycling - I know they will breed! Give the little guy something to chase once the tank is ready for him!
So, do they eat them?
