Polleni and stingrays as tank mates?

[SaltyPlum]

I have a 300 gallon tank with a motoro pair, 5 XL silver dollars, 9" JD and 12" spotted gar.

Came a cross a 4/5" Male polleni for a good price and wanted to know if adding the polleni would be a safe move?

I've always wanted one and I know they have a reputation for being aggressive, but it being the smallest and being intoduced to an established tank im hoping it would learn its place abd get along. Would appreciate any members suggestions/opinions before i buy it.

My Paratilapia were always aggressive with each other, and other similar iridescent spotted, similar shaped fish, but mostly seemed to ignore any species that didn't look like they did.
