Fishkeeping & breeding

Firstly I need to precise that I'm a big fan of fishkeeping, ocean world in generaly. I really loved the aquatic update 1.13 but I feel a miss.

I suggest to add a way to reproduce fishes but not in the classic way of Minecraft "eat and reproduce", I think that's could be more interesting, take care of conditions of reproduction that should not be the same for tropical fish and for cod for instance. Conditions could depend on the biome, the surface of living, or/and the number and type of aquatic plants for each species of fish.

Fish could make eggs like turtle but under water, or like frog, or just nothing but after 2-5mins, one fish spawn (little or not).

The goal is firstly to add a way to "farm food", in a smart and playful way, learn to people how to protect theses species. I add that we could make some crossing to have different tropical fishes for instance.

You can add some ideas of tell you're version of this idea.

Thanks for reading, I'm not a native english so I surely did mistakes, sorry about that.
