What other fish do you like? You could either add another cory school or up yours, stock more endlers (~10) and have a schooling fish as well (harlequin rasboras, cardinal tetras, glowlight tetras, ect) if you want. Maybe a dwarf gourami as a centerpiece. Here's what I would do
1 DG or honey gourami
15 endlers
10 harlequin rasbora
8 albino cories
8 panda cories
AqAdvisor puts this at 126% percent but they are extremely conservative in their stocking guidelines.
