I have a 210 gallon 6 foot long with 6 yellow tail Acei's, 6 Cherry Red Zebras and 3 Saulosi. I am wanting some blue color in there what would you recommend for some additional tank mates. Everything is now 2 males to 4 females I believe except the saulosi which is 1 Male and 2 Females

You will want 1 male or 3...especially on the zebras. I would add 2 female saulosi and 4 estherae (red zebras) for every male in that species group.

I like 1m:7f Pseudotropheus cyaneorhabdos Maingano for a brilliant blue.

I have heard they are tank killers?

 

[DJRansome]

Not anymore than estherae IMO. With the right tank dimensions and the right ratios and the right tank mates...most fish are fine and not tank killers.

I did have them in the demasoni tank for many years and may get them again.

I second the Pseudotropheus cyaneorhabdos Maingano... no they aren't tank killers at all, I've had them many times, and they've been fine.
