Hello.
I think these days I want to keep Cerberus rynchops.
Therefore I have a question.
Which should I use fresh water or brackish water?
"We can keep they in fresh water." clerk said.
However, when investigated, the information that the mangrove zone etc. was inhabited was found.
If they keep in fresh water, I'm worried that Cerberus rynchops may suffer from skin disease, parasitic worm, and etc.
thanks
