What is good to breed in a 10 gallon? Just want to do it for experience.
Dwarf shrimp. Cherry shrimp are easiest. Just have a heavily planted tank and a sponge.
You can’t really breed for fun though, as the tank will overstock.
After a year, you may want to start selling some for profit.
It depends on exactly how you plan to breed the fish. There will be no selling for profit, it is selling to offset some of the expense of keeping the tank.
If you intend to put fish in the tank for spawning and then remove them when they are done, there are literally hundreds of Tetra, Barb, Minnow, and other such species that will spawn in the tank. However, if you want to put fish in a tank and let them breed so that fry have to grow up alongside the adults, options are more limited. I found Celestial Pearl Danios to be a good fish for such a tank. A nice clump of Java Moss in the middle of the tank and after a while fry will start popping out of the weeds. Close relative to this is the Emerald Pygmy Rasbora, and it would also work well. I had two pair in a 5 gallon tank and had fry popping up all the time.
