Newts with fish? Crayfish?
Posted 02 May 2019 - 08:27 AM
I stumbled over someone keeping native newts with fish and really liked the idea. That said I wonder how it would work in a well stocked tank. My main interest would be in keeping an aquatic adult eastern newt in a 120 gallon tank with killifish, banded sunfish, ghost shrimp, and maybe some flag fish. Obviously I would need a land portion of the tank.
But my main concern is that apparently all native newts are extremely poisonous. This is a defense against predators and is supposed to be released if something tries to eat them. My concern is if this is released through their skin would it foul the water so that fish or shrimp die just from being in the same tank?
I see people online keeping a few small fish with newts but have not seen anyone heavily stocking a tank. Has anyone here kept newts with fish and shrimp before?
And finally I briefly wonder about newts and crayfish. My initial thought is the crayfish will eat the newt and then die from poisoning. But then I wonder if they would recognize the newt as off limits for that very reason?

I kept a couple of what I identified as peninsular newts in a 90g with a variety of fish for a couple of years. AFAIK, no harm was perpetrated by or against the newts or co-residents. I assume the newts ate some Heterandria, but I never observed that happening.

I find newts in water that doesn't hold a large number of fish. There are fish, just not a lot. I don't know if this is typical or not.

Thank you guys for the responses!
Doug based on your experience it sounds like the toxicity issue won't be a problem. I am planning on having a crayfish which unless someone tells me its ok to put in a newt I will just assume will preclude the newt. But if the crayfish becomes too much of a problem for the plants I want to have I will rehome the crayfish and get a newt.

crayfish will become too much of a problem for your fish before they become a problem for the plants. crayfish hunt at night and eat sleeping fish.
