You could do CRS an blue-pearl!! Might get a similar effect. Just get the pearls as babies and they should acclimate to CRS water conditions easier.
Which one do you want the most crystals or tigers??? In that answer might be your decision...the blue tigers are just stunning. That said from a girl with a tank full of CRS&CBS babies. I'm planning a blue tiger tank just getting everything ready for them they will be housed with blue-pearls.
Good Luck can't wait to see what you do :icon_smil:icon_smil:icon_smil
