5 ways Reef Hobbyists can lessen impact on world’s oceans
Here is a list of ways that all the reef hobbyists could do to lessen their impact on the oceans everywhere. This is an important task as we try to conserve our beautiful oceans around the world.
2-When possible, buy fish that have been captively bred
A perfect example of this is the celestial pearl danio. This fish was discovered in 2006 and immediately became a largely popular aquarium fish. By the next year, there were already reports of wild populations being close to extinction, and of habitat was being severely damaged by collectors. This is what we are trying to avoid happening to all fish that are desirable for our collections.
3-Dry rock, not live rock
The simple answer as to which you should use is you have a choice– you get to decide what critters you want in your tank and which ones you don’t.
Live rock is great in that it comes covered with nitrifying bacteria which covers up the scent of ammonia and converts it. Unfortunately, it also comes with lots of things you probably do not want to see and you don’t get to decide if you want it or not.
For example, a lot of people who have gotten live rock that has critters that can overrun a reef tank in just a few days if not taken care of quickly. Even if you remove the ones that you can see, there could be many, many more that you can not see hidden in the rock that will eventually give new life that will run your tank. One of the worst is the Kraken worm, that grow up to 4′ in length and eat corals for their meal. You won’t even be aware that these pests are in your tank until you see corals disappear or bleaching, which no one who cares for a reef ever wants to see. These pests are even harder to get out because you can’t always see them as they are very small and some only come out at night. In the case of the Kraken worm, you will have to tear apart your whole entire tank to get to them and remove them.
With dead rock, what you see is what you get no pests. I would suggest to you to buy the rock that’s been out in the sun for long enough that it’s bleach white. It won’t have anything unwanted attached to it, and top of that, you can watch your tank mature as the rock will change color as bacteria and algae grow. It is also a good idea to use live rock as a seed to help the process along, so long as you get the live rock from someone with, as I said before an established tank and there are no chance for any unwanted guests.
4 No Cleaner wrasses period
- Damselfish were smaller sizes than average.
- Fishes that typically lived in the area were 37% in population
- There was 23% less species richness per removal reef.
- The removal reefs showed a incredible 65% reduction in fish likely to move between reefs, or juvenile visitor fishes.
- There was 33% lower species quantity of visitor fishes.
- and finally, 66% lower abundance of visitor herbivores such as Tangs.
Quite frankly, cleaner wrasses have an impact on coral reefs, to the extreme, that they impact the ecosystem by being removed. This study makes it obvious to see that their removal creates less healthy fishes, by means of smaller fish sizes and reduced populations.
“It isn’t just a $10 fish at stake. It’s an entire reef community you impact with your purchase of a cleaner wrasse.” Leonard Ho said.
The most important impact these fish have is the cleaner wrasses ability to attract fishes to join a reef community. When they are removed it drastically lowers the amount of fishes that decide to visit a reef. The effect they have on our oceans is amazing, and when we remove them for our pleasure, we are hurting our oceans we claim to love.
