Hej, en av deltagarna på APD (Aquatic Plants Digest)-mailing listan har problem med att artbestämma en fisk som han av misstag fick med från akvarieaffären.
Ni som gillar utmaningar, kolla bilderna på följande sida och kom med något förslag.

Siamesisk algätare ska det inte vara, mer likt någon tetra. Den är väldigt stillsam, "svävar" mest omkring, har inga skäggtömmar, dess fenor är ofärgade.Den är 4-5 cm lång.
<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>citat:<hr height=1 noshade id=quote>A big clue I suspect is how this fish behaves. As I mentioned, he is
quite passive in nature and his swimming methods are quite unusual.
Rather than appearing to actually swim, he seems to hover and dart around,
but fairly slowly most the time.
My unidentified fish does not resemble a SAE even remotely when you
see them side by side
1. Does the mystery fish have an adipose fin (small unpaired, often fleshy fin on the top surface of the cadule penticule, just in front of the
tail)?
Nope!
2. Do any of the fins have any color, or are they all clear?
They all are clear as far as I can tell.
3. Does the fish have any barbels (sometimes they can be very fine and difficult to see)?
Nope!
4. How much space (relatively) is there between the vent and the placement of the ventral fin (the unpaired in on the lower surface of the cadule penticule, between the vent and the tail)? For example, in a livebearer (female) the ventral fin lies directly posterior to the vent, while in a lot of other fish there is a considerable distance between the vent and the fin.
Pretty difficult to tell, but it looks like they are quite close
together.

Där har ni kanske något att fundera över?
