Do they prefer shrimp or snails? How many shrimp do I need before adding the puffer?Dwarf puffers will go after almost any snail since it basically gets its beak in there to eat their flesh but leave the shells unless they are really tiny snails...
Fat Homer Could I do a Dwarf Puffer in my 4 gallon with the Scarlet Badis? There are plenty of snails and plants to keep it distracted.
+1Tough call... since a 5-10G is usually the minimum that most recommend, due to their activity levels, but i guess in a planted 4G a single dwarf puffer could do okay, just watch out for fin nipping...
