| You didn't upset me. I was giving examples and an explanation.
This happens frequently. People think that they are doing their fish a favor (and in a way, they are), by putting them into the wild when they outgrow the tank. The problem (especially with prolific breeders like rabbits, rats, and fish) is that all it takes is two individuals of opposite sexes to populate an area. I can't find any information on the size of a lionfish spawning, but considering their spawn are called "larvae," it is likely to be a pretty big spawning. Then, considering that there is little, if anything, in the Atlantic that possesses the ability to get past a lionfish's formidable defenses, any young produced by that one spawning are likely to survive and thrive.
The idea that one or more pairs of lionfish found each other over the past few decades is more likely than a pair of lionfish surviving a trip through the Antarctic (or through the locks of the Panama Canal).
This is a problem that we talk about a lot on Fishlore, usually every couple of months. Last year, we had a discussion about a New England pond that had Chinese lungfish living in it (the state it was in decided to sterilize the pond rather than risk them spreading). |
