I have a 30gallons fish tank and I was thinking about getting 2 honey gouramis, a rainbow shark and an ADF. I'm escaping the tank so that it has lots of hiding places and an area where its shallow for the ADF to chill on. I was wondering if I could feed them small live fish or maybe frozen shrimp, but I am not sure if those type of fish are predatory, or if they would even eat the fish.
