Natural immunity of aquarium fish, explained by the fish doctor Gerald Bassleer in the Fish Room(NZ)

You mentioned just a little bit earlier natural immunity from wild fish. Can you talk to that a little bit and how that kind of works, behaviorisms and all that kind of stuff, please. Well, as long as the fish lives in contact with parasites and bacteria nature, he develops an immune system. It's like we as humans, you know, we live daily with bacteria and viruses and we have known and learned. If we have regular contact, we regularly maintain our immune system. If we shut off the contact with bacteria, we disinfect all the time. We avoid any contact in social context. We lock ourselves down while we lose our contact with the natural environment and we lose our natural immune system. That is a permanent training program and that's something that happens in nature. The fish have permanently a challenge, a challenge to fight off the bacteria and the parasites. That doesn't mean they're healthy, but that means they have a way to survive. The problem in breeding of the fish that they are in an enclosed specific environment with specific food. Always the same food, the same water and the same conditions. So their natural immune system is not natural. It's not natural. It's an stim. It's an artificial immune system. And sometimes what happens with the tank raised fish, they come in contact in an aquarium with wild fish or fish from another breeder and they got in contact with bacteria and viruses they have never seen before. That's sometimes the problem when you start mixing fish from different origins. For example, the, the discus people, the discus world. The main thing I always tell to the people who keep discus because discus is an expensive fish. Never mix different origins unless you have put them in quarantine and challenge them with the water of the other fish. But don't introduce wild fish with tank resources from Germany or Thailand or Vietnam. You're going to have problems, obviously very high risk. And it's the same for humans. We travel to Africa or to the Amazon or I would come to travel to New Zealand. Yeah, I would have a risk that I get attacked by bacteria and viruses from New Zealand that I don't know in Belgium. I should be aware of that. So I have to be make sure that my immune system is well taken care of. That means I rest well, I eat well, I have a good health, I do a good maintenance of my body. And I try to be natural influence. And that's a basic rule in life. People with a natural immune system, the people who take care of their body necessity for fish, take care of your fish and they will have a good natural immune system. That's with good water, good food, avoiding stress and the fish will develop and get a good natural immune system. Absolutely. That explains it in a words that I said. Do you think.
