Good? They are great quit young though barely an inch not including the tail
As long as they don't get aggressive to each other you will be fine.
Part stress, part adjusting etc. your nitrates are a bit high for rams. Who are sensitive to then. I would do a water change.but wait till they have been in the tank 24hr. It would just add stress now. With rams you want to keep your nitrates as low as possible. 10 or under is good.
I don't have any stress coat what is it?
I don't know what it is at all what does it help where do I buy stress coat
