Should I worry about cross breeding?

[kipa25]

I got a bunch of cichlids, very cheap, a couple of days ago. All are around 1 inch to 1.5 inch.
I got:
-Marmalade Cat 1m2f
-Benga Sunshine 1m2f
-Eureka Red 1m2f
-Ruby Red 1m2f
-6 yellow labs (unsexed)
My tank is 60 gallons and has a sump (filters up to 90 gallons) and a rena xp3. I know it overstocked, but if crossbreeding is an issue would it be okay if i kept the males and yellow labs?
All look a little grey for now but ill wait till they color up and then try to vent them
P.S. Im new to cichlids ,so any help is greatly appreciated. Thanks

If you aren't looking to breed, Id get rid of the females...and yes there is a chance you will have crossbreeding, I believe all your peacocks are capable of breeding with one another, not sure about the marmalade cats though

Clown is right all the peacocks can breed each other

Ok thanks guys... ill probably keep them for a few more weeks and vent them, they are still pretty small.
