ok so I gave in....I noticed my armi moving its jaw up and down and sometimes leaving it open....well I know that Piranha do that when they are hungry so I gave in and froze a minnow for 20 minutes and threw it in the tank. Right when it hit the water the armi swam to it...inspected it a couple times and swallowed it. Ive decided every 2 days ill freeze a minnow and feed him for 2 weeks just so he can get adjusted to frozen food. Next ill try pieces of tilapia fillet, if that doesn't work i'll switch to silversides
