I just saw the Piranha episode of MQ.  Wow…talk about scrapping the barrel for topics.

Fish, at one time, were a great hobby of mine.  At one point in my life, I had seven tanks going, all with very unusual and exotic fish.  This does not make me an expert on piranha.  But…I'm probably one of the few people in the US who have had both Redbelly Piranha and a true Black Piranha as pets.  So I do know a little bit on the subject…something that I'd like to share.

The premise of the show was to determine if a school of Piranha were in the Lake of the Ozzarks in Missouri and could they survive.  I share the same opinion as the biologist who has been working the lake since 1991….and that opinion is "Um…no."

Let's start with their strongest point.  They went to a water source and determined that the low temperature was only 57 degrees.  I question that finding, yet…ok.  Not exactly sure how the piranha, who are not indigenous to the region, would know where this spot was and would they be able to find it year after year?  Um…no.

Now let's discuss the "common sense" approach to the problem posed by MQ's resident idiot marine explorer.  *In my best idiotic voice*…"It's a BIG lake.  If someone dumps in a pet…how would people keep fishin' them up?  Just doesn't make sense."

Hmmm…it would if you knew anything about Redbelly Piranhas (Serrasalmus nattereri).  They are NOT some crazy super-dangerous monsters.  Actually, they are quite timid fish.  Fish that will not confront their prey but instead will ambush it in a cowardly fashion.  After feeding them, I routinely put my arm into to tank to move around plants or for just routine maintenance.  They never came near me.  Not much of a monster.  Oh…back to the idiot's theory…

Someone throwing a pet fish into the lake isn't going to take some back way access into the lake.  They will throw it into a bucket of water and dump it near an easily accessible pier.  Since Redbelly Piranhas are shallow water fish and timid fish at that…it probably isn't going to stray too far.  So when a little girl fishes off a dock and pulls one up, which is what they were droning on about…well, it's not exactly proof of a breeding population, is it? 

Also in the show, the went to South America to show how mean piranha are.  For examples of this, they used the Black Piranha (Serrasalmus rhombeus).  Comparing a Redbelly Piranha to a Black Piranha is like comparing a fat, lazy house cat to a Saber Tooth Tiger who's DNA experiment went terribly wrong and it's now 30 feet long, can breath fire, and turn invisible.

I cannot stress how much I do NOT recommend that someone takes on a Black Piranha as a pet, even if you are very experienced with fish.  Just to clean the tank, I would have to box her in with plexiglass…if not, she'd jump out and try to snack on me.  Without question, it was the most dangerous fish that I have ever owned.

Anyway, I felt that it was a classic…and excuse the pun…a "bait and switch" move on MQ's part.  Show how dangerous the Black Piranha is and relate that to the Redbelly Piranha and hope nobody catches on.  Whatever…

Overall…just weak sauce all over the place.  Your monster is something that people in the northern half of the country can go and buy as pets.  Yet…I do give them a couple of Revenant Points.  Why?  Because at least these "monsters" are real…

I don't think piranhas would survive very well  in cold water, especially the further north in the country you go.Maybe here in South Texas,since we rarely get snow or ice, and if we do, it's only for a day or two.

And your right, someone would do exactly as you say to dump the fish. If for example I had such a pet and wanted to dump it, I'd just going to take a bucket and walk down to the park along Cibolo Creek and dump it in. And your right, one fish doesn't mean a breeding population.

I didn't know there was a red belly piranha.All anyone hear's about is the black bellies.But your right, they are dangerous.

I'm surprised they haven't done the story about alligators in the sewers of New York. I've heard this urban legend for years.I do know some people have baby alligators as pets. In fact, I once saw on Animal Planet on the show Animal Cops, where they raided a drug dealers house, and the guy had an alligator in a tank.It wasn't fully grown, but was still pretty big.In fact there is near New Braunfels ,an Alligator Creek.

Thanks for the information on the piranhas.I'm glad you shared the information with us.

Hey HollyDolly, they actually have done an episode on that:  Season 3, Episode 5 – "Gators in the Sewers".    Smile

HollyDolly-  They did a single experiment concerning temperature.  It did show that Redbelly Piranha ran into some serious problems below 55 degrees.  I do applaud them for doing the experiment.  However, I would caution anyone to take away anything from a single experiment.  Much more testing would need to be done to prove anything definite.  Yet…for anyone who knows anything about fish…throw a tropical fish into cold water (below 60 degrees) and you've got a dead fish.  This is pretty much common knowledge amongst fish enthusiasts.  Your heater breaks in winter and you don't catch it…dead fish.  It's not exactly rocket science… 

They judged the temperature of the cold water spring to be 57 degrees all year round, including winter.  As I previously stated, I question that, yet…it doesn't really matter.  I still don't believe that the fish could survive in it for months on end.  The experiment on the show was done over a 5 day period, dropping the temperature from 78 to 50.  So really, the piranha were only in the cold water for a day or so.  In the wild…we're talking months.  And all of us know that through brutal cold spells, the temperature can really drop, thus severely dropping the water temperature.  I'm just not seeing them surviving.

And it's not surprising that you aren't acquainted with the Redbelly Piranha because you're in Texas and they're illegal in Texas.  In fact, here's a map that shows states where Piranha are illegal:

http://www.angelfire.com/biz/piranha038/images/Prohib_P.jpg

I was in both Michigan and Illinois while I had my two species of piranha.  Quite legal there.  I did live in Houston for quite a while and I do agree with the law.  You just can't have piranha in warm water states.  Then again…there are plenty of things in warm water that are much worse than piranha.

And just for the record, there is the Redbelly Piranha and the Black Piranha.  The Black Piranha, which is typically extremely rare to find in the US as pets, can be generally applied to several species, but typically it's the S. Rhombeus.  Yet…there is no such thing as "black bellies."  You know, just sayin'… Laughing

We had a piranha scare in Ohio a few years back.  An angler caught a a pacu in the Scioto river, and people started freaking out.  Over a pacu.  But they kind of look like pranha.  And of course the news latched onto it.  "Could there be piranha in Ohio?  What you're about to see just might save your family's lives."  Like you said, "Um, no".  The Scioto freezes over for crying out loud.  Think, people!

Wallydraigle- That's just one of those stories that warms my heart.  The mighty Pacu terrorizing Ohio.  Excellent…

Oh man…and speaking of that…I forgot to mention one of my favorite parts about the MQ show:

The brilliant MQ marine explorer (and I'm not quite sure how one obtains such a title…therefore myself and all of you are also marine explorers now…) had this killer idea to throw a dead plucked chicken into the lake.  This would surely draw the dreaded piranha out into the open.  They tied it down, set up a camera and waited.

When they returned…the chicken looked like something had eaten a bit of it.  The guys were very excited about this.  The one guy mentioned that it looked "shredded."  To me…it seemed like a water-logged chicken that was kind of naturally deteriorating.  So, perhaps the word "shredded" means different things to he and I.  Anyway…

They show the film.  What does it show?  Bluegill!  Oh…the horror!  Hide the children!  Somebody send for local professional shark hunter Quint from Jaws!  For anyone who doesn't know…Bluegill are harmless little fish found in many fresh water lakes and such.  On the "Oh My God It's A Monster" scale…they rate a half a step above Goldfish.

And the absolute best part…the brilliant MQ marine explorer guy would have none of it.  The water was very murky he would say.  Maybe they just weren't captured on film.  This guy just wouldn't give it up.  Seriously…the pathetic meter on this episode goes to 11…most shows go to ten.  But this one…just had that little extra nonsense…
