Yes, you have many large fish in that tank, you've only hadthe tank for two weeks now. Have you cycled your tank yet, and how did you cycle it? I would be worried for many of your larger fish that you have been adding.
Also, while your tank is so large, I would venture tos ay it is overstocked and you may want another opinion.
Your Tiger Shovelnose Cat will grow to 3' large and a 180g tank is the minimum size.
panasius cat.
pterodorus granulosus.
common pleco.
pims catfish
[These four tanks require tank sizes close to your 180g tank size so all together it makes your tank kind of full]
cute little clown loach.
2 6" parrot fish. [Do you mean parrot cichlids? These will grow decently large]
Your cute little clown loach can grow to 1' and you should have at least 6 of them since they are schooling fish and very social fish.
I would recommend cyling your tank because in two weeks I'm assuming you haven't and give away all your fish or sell them, and rethink your stock.
