Object or artifact?

    This DECaLS object (not central galaxy), pic below, doesn't seem to be showing up in visible light, but clearly in Models / Residuals.

    What is causing this? It doesn't looks like DECaLS artifact to me. I searched other surveys but then either shape or position aren't the same
