Aquariums: Are redchin panchax begginer fish or difficult to keep??

I was looking for a center piece fish for my 20 gal with 8 pygmy corys and this fish caught my attention because originally I was gonna get golden wonder killis but they get too big and would eat my corys.. But the redchin panchax only gets about 2 inch mabye 2.5 so I personally think I could keep a pair or possibly trio IF they are for easy to care for because ive only kept fish for about 2 year ish. my water parameter are: 15 gh (267 ppm) 5 kh (90 ppm) 6.8-7.1 ph and temp is set to 74 f. Opinions?
