Hello, I recently got these 8 myleus schomburgkii wide bars about a month ago but the more I read about them it seems like there's different types of wide bar silver dollars. Or that they look different depending on where they are from. I was wondering if you guys could tell me which ones mine are? And I was also wondering why some of them don't fully display their bar, is it due to there being more dominant ones in the pack? Any other extra info is greatly appreciated. They are currently in a 125 gal growout but would eventually want to house them in a 600 gal with some datnoids and Arowana
