Why is the Lionfish bad for the reef?

The Lionfish is originally from the Pacific and the Red Sea.

In 1984 the first Lionfish were spotted around The Keys.

Since the beginning of the 21st Century the Lionfish is spotted more and more and everywhere.

The fish itself is not bad for the reef.

Their habits are bad:

NOT EATEN

They don't have natural predators in the Caribbean.

So the population is not controlled in a natural way. 

Their natural predators are Groupers, Barracuda etc., fish you can also find in the Caribbean. But here they're not used to eat Lionfish. 

And besides, all the really big fish are caught by human.

EAT A LOT

They are greedy! 

They eat everything, even their own species. 

As long as it is fresh or frozen.

REPRODUCE QUICKLY

Lionfish start reproducing within 1 year. 

For example a cod fish within 3 to 4 years.

They reproduce 30.000 eggs a time.

Every 4 days.

+/- 3.000.000 eggs a year
