Two questions here:

1) A few weeks ago I purchased six of what were sold as Rummy Nose Tetras. From the information elsewhere on this site I realise they are in fact Firehead Tetras. Five of the six quickly showed off their lovely red colouration, but the sixth took a day to fully show the colouring. Looking closely at the sixth fish the white stripes on the caudal fin are actually cream almost yellow. The other five white striped fish shoal closely, but the sixth cream/yellow striped fish spends less than 50% of the time shoaling with the others. Is there much variation in the caudal fin stripes, and why is the cream fish a loaner? The fish seems perfectly healthy in all respects. I’ve not seen the yellow stripes in any pictures of this fish.

2) The fireheads consistently restrict themselves to the lowest quarter of the 250ℓ aquarium. Is this typical as I did not see it in notes for this fish on this site. They are not threatened by other fish, their companions are false neons and ember tetras.

I've never heard anybody call these fish "firehead tetras". They are universally known as rummynose tetras.

This very site (Seriously Fish) calls them Firehead tetras http://www.seriouslyfish.com/p.....file.php?g...heri&id=515 and says that whilst they are very commonly sold as Rummynose tetras, those are in fact Hemigrammus rhodostomus http://www.seriouslyfish.com/p.....file.php?g...omus&id=516

The pages also state how to tell them apart.

Wikipeda also refers to firehead tetra.

Umm yeah I've never heard anyone actually call H. bleheri 'firehead tetra' but thought it better not to have two species with the same vernacular name in the database. /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" /> Think Mr. Bleher himself might have first referred to it like that?

Steve do you think you'd be able to get a photo of your 'oddball' fish?

Yes I can get a photo in the next few days. The trick will be to get the white balence correct, and one of the standard fish in the shot too. That way the difference in the colouring will show correctly.

Here are a few pictures. I have also noticed that the dorsal part of the different fish shows slightly gold, instead of the silver of the normal fish. I've done my best to photograph this, but it has not been easy.

Hmm definitely one of the two Hemigrammus at least (a dark blotch at top and bottom of caudal peduncle). Do you know if these were wild caught Steve?

The fish were purchased from Prestwood Petzone. Sometimes they list fish as Wild Caught (as they did when my partner bought some Norman's Lampeye). These were not labled like that, but that does not mean that they were not wild caught. I'll ask if they know next time I am there.
