Hi,
Matt did a great job collecting photos/info on the different species of the indicus complex just for a pic reference.

Anyway, I swear I've seen a stomach content review for indicus, but cannot find it now. Lots of crabs...
Also, personal opinion, stick with the bugs, they're a perfect staple (I love dubia as a feeder)... crayfish and prawns get expensive
*just fyi, indicus used for example as they're better researched, and thought to be similar
Hi skip, been a while.
