i feed it medium feeder guppies.. my aba loves them
also small shrimps when they are available in the LFS, mine's always been tough i have 2 abas and when they were small i placed them temporarily in a 50 gal tank separated with a glass divider and they would try to bully each other 
. Can you upload a movie while it is cruising? My aba-aba is about 10 inches, and it hides all the time. I am thinking of getting a 24" specimen, but I think that size needs to have it's own tank. I am scared to let it go in my 330 with my big Dats.
