what do u feed them?

Michelle, it is a Heros Efasciatus, most probobly male, even red line/dots not too intense on it head. How big is he? Did you just got him? Very nice fish. Don't forget to give him Romain hearts lettuce, and some other veggies daily.
JD bellow is a female..

he is about 7 inches, the female around 6, i got him about 2 months ago, owner of LFS was cleaning out his tanks to grow out some others and wanted me to have this pair, so I took them in. TJ she eats almost anything, he is picky, the only thing he really seems to enjoy are bloodworms and brineshrimp(live) when I put them in. Thanks Alex I will feed it to them.

Nice.
