i think that it is nice that fish are in the caves it adds a way to get food when underground but I have found fish spawning in singular water source blocks below y-0

his is a single water source block (source out of view) as you would find in the old caves but at least 10 fish have spawned in it. another example

fish can be seen getting to the bottom of the water and a lot of bonemeal and raw cod can be found. i am happy to be corrected if this was intensional.
to confirm this is a singular water source just higher up in the cave that is flowing down so the blocks the fish spawned in is not a water source block.
