those frogs seem fun! glad that they're all two separate tanks, otherwise I'm sure not much left of the frogs after parrots give them a nibble...
In doing some research on parrots I stumbled across this idea of "first generation" and "later generation" parrots, where the original ones had many more issues than the current ones, including a mouth that doesn't allow them to feed properly, swim bladder issues, etc. From what I understand, parrots for sale these days are more "healthy" than the original ones were. I assume there is still quite a bit of variation however, depending on the source/breeder, so I can't say that this is any kind of rule, but that's just something that I came upon in my reading.
I hope that Cinders and Flame become better buddies over the next few weeks! By the way, what kind of water parameters do you have? I've heard that parrots are pretty hardy and can adapt to a variety of parameters, but I'm curious what is working for you at the moment?
