Would a dorado work with my tank/fish?

[focker]

Well the ATF and payara are the new guys while the dat has been in the tank for close to a year now.

theres no way i would do it. chances are ur payara will be the first to die then ur atf. if u can get 3 inchers and u want to keep them for awile and get rid of them id say go for it but as they get larger the mean streak comes out.

If you start seeing welts on the payara from the dats, divide it soon or put in a separate tank. Payara will stop eating and won't last long afterwards.
Good luck on the dorado, lookin to do the same down the road
