Are pictus catfish compatible both temperament wise and water condition wise with silver dollars

I have a 38 gallon tank with 2 silver dollars(about 3") and 1 clown loach. Would 2 or 3 pictus be good companions?

They shouldall get along okay but the Loach would really prefer a higher pH than the other 2 species. Also the Loach and Silver dollars are schooling fish so you might want to consider getting more of those 2 species as oppposed to adding a 3 rd species.
