Obsessed with the Flood - # 1 Freshwater and Saltwater

>

The problem of saltwater and/or freshwater animals often is used to try to pull down the feasibility of the Flood model as effective tool to understand the formation of the today's world biology and geology:

[Q] Just like all fresh water fish will die in salt water and massive temperature changes.

[A] No they won’t actually, if they have a chance to acclimatize gradually. I saw this for myself many years ago at Underwater World in Queensland, Australia. They had a freshwater and saltwater fish in the same tank. They achieved this by gradual adjustments to salinity in both fish until they could cope with the same salinity.

The excerpt taken from the page:

 ....gives us a good hint to understand the conditions at the moment of the Flood, which allowed both freshwater & saltwater fishes to survive: thermocline and especially halocline.

Halocline is the gradient (difference) of concentration of salt in seawaters, along the vertical dimension of the sea ("is a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water" - Wikip.).. 

BUT the gradient can be also HORIZONTAL:

Q: What happens where fresh water and salt water meet?

A: They mix, sometimes quickly, sometimes slowly. Some mixing takes so long that people think that they are not actually mixing.

I dare an explanation for the existence of freshwater fishes in inner continent lakes, rivers, even lakes on mountains: being the freshwater density lower than saltwater, in many cases the vertical separation was stirred in an horizontal one. In many cases  the freshwater  could have overlapped on the deep layer of high salinity waters, the freshwater naturally submerged the tops of mountains and/or the surface of emerged continents, as the saltwater flew away - bringing there the fishes living in the freshwater:

 The Flood and the Ark are not a tale of fantasy, but something that happened and GOD wanted humans to keep a record of that event, to continually recall  the judgement waiting for them.
