Stocking and moving around fish 225g and 75g

[try2catchmike]

This is what I have and they are all still pretty small,
225g
-Blood Parrot
-Jack Dempsey
-Red Tail Shark
-3 Giant Dainos (May add more or just get rid of them)
-4 Silver Dollars (Will probably add 2 more)
-Jewel Cichlid
-Green Terror
-Gold and Green Severum
-Firemouth

I was thinking about maybe adding some catfish or something different because it looks kind of boring all these fish occupy about the same space and the bottom is empty. I could also move some back over to the 75g because honestly the tank is a bit boring.

75g
2 Peacock Cichlids
Convict Cichlid(May get rid of, its still small)
African Knife Fish

I was thinking about making this an african cichlid tank since I already have a couple. Its basically empty because I moved most of the fish over to the bigger tank.

i think that a poly would work out nice in your tank if you want to keep it simple a common senegalus will do (as they stay small and can't eat anything in the tank other than the danios) However depending on the size of the others you may want to grow them out a little more or you could just buy a baby sen and have them grow-out together
