Hi all, just recently brought in a full box of small cardinal tetras from Columbia(still living in hope of eventually finding Apistogramma diplotaenia as a bycatch)

The contaminants always thrill me more than the cardinals and is the main aim of bringing in so many. This time they sent small cardinals and amongst them around 12 Poceilocharax weitzmani and a few unknown tetras, amongst them is this characin which i cannot ID, it looks to me to be a Odontocharacidium possibly cf aphanes but im not at all well up on this group of fish and dont know the distribution of Odontocharacidium.

Any help would be much appreciated. I only got 2 so ill be a lucky boy if they are opposite sexes!! for now im just feeding them well and putting a bit of meat on them.

Poor pic but they hang at the back of the tank and are difficult to capture.

Here's a picture of some Odontocharacidium aphanes that I bought from Glaser last year:

The males get a nice deep rep colour.

Do you guys ever get Gnathocharax steindachneri as a contaminant among shipments of cardinals?

Also, and more on topic, are Odontochcracidium as easy to keep as Characidium spp.?

I've never kept any Characidium so I can't really compare the two. But Odontocharacidium seem pretty easy to keep. I've only fed them with live foods so I don't know how they react to frozen food or dry food. And they aren't active swimmers, they stand still most of the time and when they move they seem to dart about.

Thanks Pete.. Appreciated. Its a long shot but if i have both sexes they will become a breeding project!

I had to google Gnathocharax steindachneri and the answer is no, ive dont think ive come across these, ive had similar fish but not that one..

Ive not had Characidium before so cannot compare, ive only just started keeping Odontocharacidium so cannot comment on their upkeep although upto now they are doing ok, feeding on plenty of live baby brineshrimp and keep fairly stationary close to the substrate..

Does anyone have any further info or tips about keeping Odontocharacidium in aquaria?

Fairly easy to keep provided you can give them small live foods such as brine shrimp nauplii, grindal worms and Moina (Daphnia will be too big unless you sieve them. They seem to prefer soft acidic water and males will get a bright red body colouration. Males also defend small territories chasing away both other males and females. Some people have reported them being extremely aggressive and killing all conspecifics but I haven't had that experience. 

Wouldn't keep them with anything other than very small and timid fish. The Odontocharacidium are not active swimmers and they usually look like they're hovering sort of like a humming bird rather than actively swimming around. When they do move it is with a very darting movement. 

 

I would also go as far as saying that it's probably one of the smallest characins? Never managed to breed them but I've heard people have been successful in doing so in "V-tanks".

Great info, thanks Gustav. Don't think many characidiins have been bred in aquaria so interesting to know this one has.

There was a text about keeping and breeding of O. a. by M. and P. Hoffmann in Datz some years ago. Before 2000...
