Breeding

[newfishaddict]

Hi, eventually I want to try to breed my "Red line torpedo barbs (Denisons barbs)” Puntius denisonii. I expect this to be a great challenge and welcome it. There is little or no information available regarding breeding these fish. Any ideas?

I know:
-I want a mature male and female that I condition on live foods while each is alone in a tank (does this actually mean live or does it mean frozen foods?)
-then I transfer each of these fish into the same tank that is at least 3 feet long.
-raise the temp to 81 F
-use lots of java moss, or some means to protect the eggs.
-removed the pair after mating

I have noticed that these fish are called barbs, but they do seem to resemble Flying Foxes in many ways, any comments here?
àI am going to do some more research into the taxonomy of this fish soon….

I don't know about breeding them
but they are also known as
Barbus denisonii, Crossocheilus denisonii & Labeo denisonii
the valid taxa is Puntius denisonii.

here is fishbases listing for it
http/www.fishbase.org/Summary/speciesSum...sname=denisonii

and here is a list of references they used

>>> the valid taxa is Puntius denisonii.

There are a great many people who do not accept the validity of the genus "Puntius" and will regard all "Puntius" species as "Barbus". If you put a "Puntius" man and a "Barbus" man in the same room and let them go, you'll get a blood bath.

The important thing to recognise is that if a fish is called "Puntius xxx" and you don't get many google hits, try searching for "Barbus xxx" as well.

The fact that Barbus denisonii has not been bred makes me wonder about the classification. They are expensive fish, and that usually encourages those with $ signs in their eyes to breed them, either at the hobby or farm level. There has been no good record of this suceeding which for a barb is most unusual as they are ready breeders. Makes me wonder if they are Epalzeorhyncus, Crossocheilus or similar which are a totally different prospect with regards to breeding.

It suggests that the fish is not a barb at all, or that to date, all the fish tried have been immature. There are a few other possibilities, (remember when M. boesmanii was first imported - they were all males...).

My barb breeding procedure is described in this thread. With adult fish and the right water chemistry, this has rarely failed. There are tricks if they are retiscent. Sudden water temperature drop of a few degrees suímulates rain - often works, (very good with Rasboras), dropping the water level has the same function, it simulates the flooding of otherwise dry land, this also announces the rainy season.

I don't have the space to work with them at the moment.
