nice sev, I have 2 green sevs male and female breeding pair they are beautiful! Especially for a green severum which is the less colourful ones take a look at my pictures and you will see himSmall schooling fish would just make for fast moving snacks for big cichlids. Silver dollars are fine with the big guys. I have 6 in with a JD, green terror and 4 Severums in my 125. Look into Severums if you want colorful large cichlids. This is one of my red spotted sevs.
