Presently I have 8 White Labs and 8 Saulosi in a 55 gallon tank. I know I have four male Saulosi and equal number of females. I have eight female Saulosi in a 30 gallon qt tank. If I added them to the 55 gallon giving me four males and twelve females. This with the White Labs would total 24 total for the 55 gallon. Is this too over stocked?
