What species does these code refer to?

[keehoe]

Hi all, my friend send me some eggs and two of which having label: R.xip and N. Run. Any idea what species these refer to?

[whuntley]

Rivulus xiphidius is the first one.

The second one is a total mystery, to me, unless the "b" turned into an "n" and it is Nothobranchius rubripinnis.

In this day of cheap computers and printers, bad writing on fish bags is a thing of the past. Permanent markers harm the fish, anyway. They contain lots of toluene, and even methylene chloride, and go right through the plastic.

Clean printed labels are less likely to be misread, and can be protected with a strip of scotch tape to keep ink-jet ink from running when wet.

PS. If it is wrong in your data base and you use printed labels, you can propagate the misinformation all over hell and gone! :-)

Thanks Wright, I have just receive confirmation from the sender and check our local census maintain by JianYang. It is currect, but our census also show RUN. for Rubripinnis. Any comment?

[CM Media]

RUB is used to represent Trigonectes rubromarginatus
RUR for Nothobranchius rubroreticulatus
RUI for Rivulus rubripunctatus
RUP for Aplocheilus rubropunctatum

And thus RUN is use to represent Nothobranchius rubripinnis

Hope I get it right. Anyone wants to comment on this?

My only comment is - If you're right, it would mean it's the second time Wright has been known to be wrong

I'm sure he's right, though I haven't bothered to check ROTOW, which is about 18" away, right now.

Sheesh. Do we have to keep score?

Wright

[stormhawk]

Wright, its not a football game so scores aren't too important here.

Back to the issue, yes, XIP is Rivulus xiphidius and RUN is Nothobranchius rubripinnis. RUN is also applied to those Nothos labelled as Notho. sp. aff. rubripinnis.

Therefore those from the Lisinjiri River and Mbwemkuru River populations are also given the code RUN.

Guys, now i have another problem. My friend mix the egg of
Fundulopanchax filamentosus "Ouidah, Republic of Benin" + Rivulus xiphidius together. He say Rivulus xiphidius's egg is much larger
should be able to identify by sight.

Can i raise them together and able to tell which species they are from after they hatched? Their female should be very different right?

[stormhawk]

Yes you can tell them apart quite easily. By body form alone and eventual pattern you can tell them apart very very easily.

[whuntley]

Also, the big ones eating the little ones will all be XIP, I suspect.

Wright

[keehoe]

In that case i wait separate them only after they hatch. Fundulopanchax with long tail and prefer surface while xip like to stay near bottom of the tank. Am i right.

[stormhawk]

Not exactly. The fry will usually be all over the place. At a certain size once some colours develop you will be able to see the differences clearly.

Even if they don't eat one another, I still don't encourage you doing that. You'll have greater satisfaction knowing how many fry you've left per species

...Fundulopanchax with long tail and prefer surface while xip like to stay near bottom of the tank. Am i right.

Kee Hoe, since you're unable to differentiate Fp fry from Riv, may I suggest that you raise and sort them by size until you can confidently say, "Yup, that's a gardneri".

Raising a bigger group of fry has the advantage that there's less uneaten food, provided you don't overfeed in the first place.

Regardless, do have some ramhorn snails in there. You may not fully understand their purpose but it does help.
