Hello
I have Travancoricus too
It`s really nice and funny fish. 100% freshwater.
Mine eats red mosquito larvae, grindall, and small sniles. They dont brake the shell, they bite and bite their meat, until the snail is too weak, and can be sucked out of it.
I`ve put in a different tank what i think is a couple...
These one should be the male
and those, maybe, a couple
