what might have happened?

i had a 2-3" blue acara i got 2 weeks ago,i just purchased a salvini and a jag the same size about a week ago. They have been hanging together with my 2 O'S which are about 8" since i got them ,eating together and getting along great . now my blue acara is gone , no trace, do u think one of my o's ate him after 2 weeks ? the only live food they have had is ghost shrimp and red wiggler worms.no fish

its possible one of the Os finally caught him, sometimes fish can just snap, but its also possible that he died (either from stress of being picked on, water params/etc) and then the other fish ate him, usually dead fish dont last to long in a tank with bigger fish, did you notice him being picked on at all? salvinis especially can be pretty brutal what size is the tank?

Salvini and Jags are very aggresive, Acara's not so much. My bet is they killed and ate him Im not quite sure how large your oscars are but if they cant fit the acara in their mouth then i'd say pass the blame to the other two.

i moved up to a 90 gal about a year ago. I didnt see him getting picked on at all they all have been hanging out togethr like buddies

if you have a jag and 2 Os in a 90g then you are going to need a seriously bigger tank (like a 6x2), and pretty soon, the jag probably felt pressed for space and killed the less aggressive acara and then they all ate it

my bro might take the o's and i will just have the jag and salvini , do jags grow fast? never had one before its about 3" now

could the BA have jumped out? there's been a few occasions where I thought a fish had been eaten, only to find it behind the tank a few days later . . .

your os ate that 2 inch fish and will eat the others if you dont get them out. put them in a grow out tank for a couple months and if you keep them all you will need a 125 minimum but a 180 would be much better.
