Keeping different CRS grades together?

[fishpoo]

Hi,
I was wondering if anyone has kept different crs grades together... my concern is if i keep high grade crs together with the low grades... will their offspring be of low grade?

Yes offsprings may become lower grade.

It is better to have a tank for mixed grade and another tank for high grade CRS for selective breeding if you want your CRS to produre good grade CRS.

oh i see... i don't have the luxury of getting 2 tanks... thanks for the info anyway.... however is it possible to increase the grading if let say a SS grade breeds with a A grade for example? or would all the crs deteriorate to lower grades over time? let's say to A grades only
