Just the opposite gangster.......the three dull ones are from the HOB system. My son told me to keep the ten gallon system because it turns Xingus into Intermedias. He may be on to something $$$$$$$$
after a few days are they still different or blending in now?
Both tanks had the same type of driftwood, feeding, temp and WC. Only difference was the filter. I'll post pics at the end of the week to show if any blending happens. Currently they look the same as the day it was put in. Even the spotting and tail color looks different. One thing interesting is growth was not affected.
