Exodon Paradoxus Factoids

Origin

Amazon basin

Temperature

Regular community tank temp
Size 6 inches possible.  4 more likely.
Age  8 years possible, but many kill each other.

Substrate

Dark substrate shows them best

Security

Best kept in schools or they eat each other

Foods

Just like any other tetra

Breeding

Like other tetras but not likely

Threats

Each other, insufficient food, poor water

 

 


LA
That green airstone measures one inch.


Origin:  Originally from the Amazon River, you occasionally come across these nasty little biters at your local fish store.  They are pretty (and a bit unusual) but rarely get along with other fish for extended periods.  We would recommend that you pass these particulars fishes by unless you can provide them their own quarters.

LA
Truly a schooling tetra.

LA
Exodons work best in schools.

Behavior:  If you do decide to keep these guys, get a large bunch.  They fare fine in schools or as single specimens.  Don’t be tempted to mix them with other mean fishes.  We seen these guys back larger piranhas (which can be sissies) into a corner.  Your exodon will take center stage and wreak havoc on most other tank mates.

LA
Four-inch Exodon paradoxus in with same size African cichlids.

 

African Cichlids?  You can mix some of the other nasty characins with African cichlids, e.g., leporinus, anostomus, abramites, and distichodus to name a few.  So, we dropped three exodons in with some same size African cichlids.  After a week or so, the Africans had all retreated to the corners.  The exodons ruled the tank.  The stressed Africans wound up catching ich.  We removed the nasty exodons. 

LA
Very attractive coloration. 

LA
Pair of the mean little bucktooth tetras.

LA
Mouth of the biggest one.  I don't see any buck teeth.

LA
Here's a recently deceased one -- no spectacular dentition.

Name:  For some strange reason, these guys are called buck-tooth tetras.  I can detect no teeth of any kind on these guys.  They are, however, mean enough and speedy enough that they need no teeth.

LA
Young exodons possibly spawning.



Breeding:  We never tried to breed them.  Why would we want a couple hundred of the nasty little cannibals?  No one reports breeding them, but they probably breed like most other tetras.

LA
Young exodons look good.

Foods:  Exodons ate whatever we offered them.  Small ones were a little pickier but quickly adapted to flakes and pellets.  Naturally they prefer live and frozen foods.

LA
More mature exodons look better.

Last Words:  Exodon paradoxus are attractive, easy to keep, not expensive, and long lived.  They just don’t get along with other fishes or each other.  They’re on our Not Recommended List.  LA
 

Bertrand Sant, Malta, November 4, 2009
Hi LA Aqualand. Your site really helped give me a brief summary of the bucktooth tetra and now I've got a shoal of 16 together with 6 banjo catfish. In the article there was said that they have no spectacular dentition. Well I've took some pictures of them and wanted to share them with you so that you can post them on your site and people could see the bucktooth's dentition clearly.
Before I forget, I've kept banjos with them because they submerge in the
sand during the day and re-emerge at night for food, so they're safe with these "mini- piranha". Thanks and regards,
 

 

 

 

 

A:  Thanks, Bertrand.  I'll add your pix to my Exodon page.  LA
