why can't they put coral in the aquariums?

Question

i went to the local aquarium and they said that there is no real coral in the tank. if the coral is in the ocean, why can't they put it in the aquarium with the fish that they put in the tanks? they told me that the aquaruim has concrete shaped as coral. why?

Answer 1

it is cheaper to put in concrete and make it look better. the coral is a living organism that requires high maintenance from the zoo. they won't employ people to care for the coral. there is no reason to put it in the tanks. out in the ocean it grows on its own. it has a limitless environment in which to grow. a controlled environment is way too risky for coral. the business owners have already concluded that the best way to make money is to not have the coral.

Answer 2

I am surprised your public aquarium has no live corals. However, you certainly can keep corals in the aquarium. Reef aquariums have really become popular in recent years. Years ago live corals did not last long in aquariums but our knowledge of coral husbandry has come a long way. Corals do need some special care such as very clean water with little waste products dissolved in it and high intensity lighting to keep the algae that live symbiotically in the coral tissues alive. Many home aquarists keep live corals successfully. Live corals can even be "fragged" by cutting off pieces that grow into new whole corals. Lots of aquarists exchange these frags and thereby reduce the aquarium hobby's effect on the world's reefs. Corals are fascinating and beautiful animals.

One reason you public aquarium may not have had live corals has to do with the fact that many fish eat corals. If they decided to keep certain types of fish that eat coral they would leave the coral out. Or if a tank has lots of big predaceous fish that eat a lot of food and produce a lot of waste it would be harder to keep the water conditions clean enough for coral.

If you mean putting dead coral skeletons in the aquariums I can tell you why they do not do that. It is irrespsonsible to buy dried coral skeletons which are often sold as curios in shops because for the most part these are not washed up on the beach but live coral animals are killed to get the skeleton. That is not right when the world's reefs have enough problems. Also, dead coral skeletons are not exactly natural looking (fish are not usualy found swimming on dead reefs) and the skeletons get covered with algae pretty quickly. About 15-20 years old dead coral skeleton pieces were often used to decorate aquariums but that has fallen out of fashion for the reasons I mentioned.

Answer 3

Coral is a living organism, and it's very sensitive to environmental conditions. So, it's very hard to keep coral alive and healthy in an aquarium environment. Additionally, many corals are protected species.

With lots of work, though, it is possible to keep coral in an aquarium. Many specialized fish stores sell live coral for your home aquarium.

Answer 4

When coral dies it turns white. The fake stuff can be any color and is less fragile. Live corals are difficult to care for and many fish destroy them so people have just coral tanks with a few safe fish.

Answer 5

we are only as anxious about "WHAT" you want to paint as a results of actual reality the paint you want to observe. we've considered too many situations the position fish were poisoned by employing skill of issues positioned interior the aquarium which released poisonous compunds or chemical elements. we do not recommend putting something into an aquarium which replaced into not made to circumvent into an aquarium, so do not take this suggestion as our approval of your theory: the in basic terms paint shall we recommend might want to nicely be marine epoxy, or style interest epoxy paint, which has been allowed to medical look after 2 weeks before use interior the tank. Ceramic units might want to nicely be acceptable-glazed and fired before use. If the incorrect paint is used or the object being painted isn't inert, you would possibly want to regardless of the reality which have problems with this. if you're able to, i might want to attempt this, yet pay interest. 2-section epoxy paint.

Answer 6

mainly 2 reasons coral is very hard and expensive to maintain right (tons of equipment and time needed) and also alot of people are contributiing to the conservations of the reefs by using fake corals, the reefs are being damaged by the aquarium industry, thats why most reefs are protected from harvesting

Answer 7

Coral is hard to maintain, it has an unique feeding process and would be very hard to keep well fed and maintained. They have a hard time keeping coral alive to do research on it, keeping it alive in a fish tank enviornment would be even harder.

Answer 8

I don't know. I have had coral in my aquariums. Always dead coral tho that was cleaned really well. I don't know why they wouldn't have it in theirs when I have see coral in pet stores aquariums and they sell it. But why wouldn't an Aquarium have it, I have no idea.

Answer 9

That's a good question, I was wondering the same thing myself
