what species is this?

[Gregh]

Keeping fish with paddletails is generally a bad idea because it usually ends in the fish being eaten. Now it can be done but there is a lot of thought that needs to go into finding a fish that can tolerate the same conditions and is big enough to not be eaten, but then you run the risk of the fish stressing out your newt. So please do take all this into consideration before deciding on getting some fish.

Oh here is a link to one of my labiatus tanks.

Beyond that it apparently stresses them I had one with my algea eater recently being new to newts, and he didn't eat the whole time he was with him, once he left the newt was eating fine.
