I'm no expert, I only recently purchased a couple ADFs myself, but yes. Brine shrimp and bloodworms are both suggested for the little guys.
They won't get very big though. From what I've read, they get up to about 3 inches.
Loki, a lovely EE plakat in a five gallon tank with some shrimp and a snail.
Beo, a beautifully ugly little guy (or gal), who's fins are still too ripped and his age too young for me to tell anything beyond "small and brown" in a temporary 3 gallon.
Dr. Jekyll and Mr. Hyde, two ADFs rooming temporarily homing with Beo.
Will eventually add a matching five for the frogs or Beo, depending on so many factors.
Hope to someday own a pea puffer with possibly some otos.
