How do I Breed Two Red Oranda fish?
The method is pretty much the same for any variety of goldfish. You need to have a fairly large tank (at least a 20 gallon, preferably larger), fish of both genders, and something to induce spawning. With goldfish, the trigger to spawn is usally brought around by seasonal changes, so you’ll need to simulate the change from winter to spring – increased daylight and warmer water temperatures. A pond is an ideal setting for breeding, since everything will happen naturally, but orandas and other fancy goldfish tend to be targets for neighborhood predators if the pond isn’t deep or large enough. Some other items you’ll need that you may not have thought of – spawning grass or spawning mop (goldfish naturally lay their eggs over plants, so a bare tank is less appealing to them) a second tank (you’ll either need to remove the adults or the eggs so the eggs or fry don’t get eaten by the parents – it can be easier to move the adults). Any you’ll need microorganisms such as infusoria, microworms
