roberts tetra
 
Hello,

I have been looking for the roberts tetra (Hyphessobrycon bentosi), but I coudn't find him in local fish-stores.
I think it don't belong to the standard-stocklists.

Can anybody tell me, if it's wild-catched or captive-bred ? This fish is my favourite, I will try to breed.
I know, it comes from the upper amazon region in peru, but don't know anything about local water-parameters.

Greetings

Axel

In our profile (click the shaded name) of Hyphessobrycon bentosi, you will find data on water parameters and the natural habitat.

As for being wild/tank raised, I'm not certain. I know my fish (I have a group of these in my 115g tank) are wild caught, I got them direct from the importer. It is not a difficult species to spawn, so it may well be commercially raised. Sorry I can't confirm that. If you find it online, the source should be able to tell you; they will likely be wild caught.

Wild caught fish are seasonal, due to laws in many SA countries now restricting collection to specific times of the year as a means of ensuring the species is not over-collected and threatened. Some areas are also more easily accessed by collectors at different times of the year due to flooding, so this can also affect the availability of some species.

Where I am, this species tends to be available in the late spring and early summer. This is a truly beautiful fish, and well worth waiting for.:-D

Thanks Byron,

I agree, this fish is very beautiful, but not always available. Where I am (in Germany), I saw it rarely.
I have had the closely-related rosy tetra 5 years before in my community-tank and it seems to me, this species is very restless and it don't shoal.

Thats why I am looking for the roberts tetra. But I am still thinking about the rosy tetra, if I will not find it.

Best regards

Axel

I have had both together in my 115g, and currently there is just the Roberts (plus many other chatracins, etc. of course). These always remain in a shoal, though they are not very active (swimming). Mine remain among the plants, they do not like overhead light and will always seek out the darkest areas in the tank, so floating plants are necessary. They remain together, displaying periodically. They come out and to the surface to feed. But they do not swim around the tank, as Rummynose will do. The rosy clade is much more like cardinal tetra. Remain in groups among plants.
