You are over stocked. You've got a lot of big fish in there and 200 litres isn't all that big. You've also got a good few fish that shouldn't be housed together and require different water perameters.
5 clown loachs - can get to 18 inches each
2 green terrors - get to 8 inches or so
4 unknown cichlids - how big?
2 redtailed sharks - can get to 10 inches, although most get to about 6. Very terriatorial and should not be kept with other sharks
2 albino sharks - ditto
1 cat - what kind? What does it look like? How big?
1 bgkf - can get to 20 inches
200 litres = 44 UK gallons
You'll have at LEAST 100 inches of fish in there when they are all grown up, and that is a super conservative estimate and doesn't take into account the smaller fish.
Go onto a search engine and read 3-4 care sheets/species profiles for each fish. Find out what the recommendations are and either get a new tank or rehome some.
Even if all is peaceful now, aggression could break out at any time.
Good luck!
