What to feed a Hippo Fry

I was given a baby Hippo fry. 1inch in length. As of today I have it all by itelf in a 10g QT tank with a couple pieces of LR, a heater and an airstone.



What should I feed it?



....I have frozen-mysis but need to know if I should feed it some kind of Fry Food like OceanNutr Instant Baby Brine Shrimp
