jags for sure, i've recently named mine the demon for the reason that even though I feed it three times a day each time I feed it it acts like I have't fed it in a week.
hey i've got a sunset oscar who is 8 inces long and lives in a 200 litre community tank, and hasn't turned to eat anyone. shes got to be the best cichlid i've owned, but my fav has got to be a fully grown frontosa.
