I can only comment on the fish we get over here, They are all SW as far as i know but can survive brackish. I've been thinking about catching some and very slowly reducing the salinity to brackish.
I'm sure there are freshwater "lizardfish" somewhere in the world, but i don't think there are any in australia, i'll do a bit of research tonight cause i want one haha
Damn are they flatheads?
Man they are one very tasty fish! Never knew they were kept in aquariums either or as a freshwater specie.
I would assume they would just stay still on the sandy bottom waiting for prey as this is how they are here in Aus
Nice!
i just googled it and got it cause its cool
