i have a 40 gallon breeder that i want to set up. right now i have one fire bellied newt in a 20 gallon long, it's a really cool tank, but it could be better. i was thinking of mixing fire bellied newts and fire bellied toads. maybe 2 newts and 2 toads in a 40 gallon breeder. is there any issues, advice or suggestions about my idea, it would help greatly.
