I dont think this is a troll to be honest I just suspect they are quite young?
Look it is totally upto you if you listen or not but this is what you need to do in your tanks.
In the 180litre I would do
3angel
2gouramis
Tank-2- 190
4big convicts
Tank 3 -300litre
1oscar 1 half foot
2 Severums - not to sure about these to be honest it depends on the oscars temperment really...
1 unknown cichlid - depending on what it is
1 Plec - depending on species if its a common in the 300 if its a bn or smaller species probs in the 190
Then rehome to either a local fish shop or other fish keepers on here
6convict fry - With 4 convicts already breeding you dont have room for more pairs
1fliwerhorn baby ATM about 2-3" - should not be kept with anything in these size tanks if anything needs a bigger tank than the 300 liter to its self.
1afra - africans should not be mixed with the other fish
1unknown eel 2ft - your biggest tank is 300 liters any 2 foot fish deserves a bigger tank than that
Very large ghost knife 2ft - as above
that is putting it bluntly but it is worth saying a thankyou and a well done for starting to put the fish first I hate to tell people to rehome their fish but it really is the best thing for the fish. I genuinely want to help you and your fish but you have to listen to peoples advice here and just accept that you need to learn to start with.
And with the three weekly water changes its not terrible I know people that do worse but ideally you should be looking at weekly water changes.
hope thats helped
