Hmm....trying to decide if I want to debate this or not, but honestly, I cant control myself and a love a good discussion about this subject, so I will chime in
Good to know
I could give you plenty of examples on species that occur together in the wild and eat each other, but I wont, because what I just said makes my point.
Sounds like it would probably work, they all contain the same toxin, TTX, and are all similar sizes etc. etc. etc..
I am not very experienced with
Bombina, but from my limited research I thought they would try and eat just about everything? Why not attack a newt? Especially one as small as
Lissotriton.
Here's the thing, is there any benefit to the animals themselves? I would imagine no, so there are really only potential risks. Though it depends on the species.
Here's what you have to look out for:
Eating tankmate of other species.
Different toxins.
Mating problems.
Cross breeding.
Aggressive behavior ( not eating ).
Stress from tank mate of other species.
Suitability of tank for both species.
Suitability of temperature for both species.
There might be more, but that is what I can think of off the top of my head.
Trust me Stuart, I LOVE the idea of a multi amphibian tank, but honestly I try not to think about it because I don't want to get drawn into doing it. There is most likely no benefit for the amphibians, and possibly only potential risk.
Obviously there are some compatible species, but in general, I find the idea of mixing amphibian species to simply be denying what years of trial and error has taught hobbyists.
Thanks for sharing your views, though. I definitely feel the hobby has gotten a bit up tight about the subject ( axies can suddenly not be mixed with ANYTHING except food ). And like you pointed out, some species are probably fine together, but the majority of the time that isn't the case. I like the optimism, though.
I have said it before, and will say it again....I would love to hear your experiences with species mixing, simply to gain knowledge.
Thanks for reading
Have a nice evening/night/day Stuart.
