Looking for help from any other people

[Aiden]

So I have a newish 75 gallon tank and am just wondering on help foe litterally anything no the water isn't murky its the hard water on the glass ive gone through and wiped it and am still slowly cleaning it. Also I know I have plastic plants but In the near future I am hoping to get real plants and way more unique wood and coverage also im planning for a loach as you can see in the bottom left and hoping for any advice on the best chiclids to add I have two golfish and one koi which is a smaller breed of koi but the golfish are almost the same size because they are pigs.
