Convict may still have a bit left. That parrot is going to get huge, 8-10 inches. Judging from your picture it doesn’t look bigger than 3-4 inches. Mine is 6 inches and still small. Unless it’s the way the picture shows, none of those fish look the size you say, and have a lot of growing left.
That orange peacock, what type is it? Reminds me of a juvie red zebra mbuna (nasty guys) more than any peacock.
Do you have better pics of the convict? Hard to tell it’s a female in the pic, and if it isn’t, it’s getting a lot bigger. If female, it is going to claim half the tank during egg laying season, and if the parrot is the opposite gender, you’ve got a whole other problem.
Both jewels and convicts are crazy, they go on killing sprees because they feel like it.
Packing more cichlids works for Malawi cichlids and only Malawi cichlids (maybe some exceptions). With American cichlids (or African riverine), it increases stress and makes them want to kill each other more. Then one wins out and you have lots of bodies to clean up.
