hi all
I lost a Tetragonopterus argenteus the other day.
no know reason other than the cloudy eyes in the following pic.
however all were fine the night before and all water params were within the std for this tank

anyway to the point
this loss gave me a chance to photograph the fish against a ruler and it has given me an idea.
if we loose a fish, for whatever reason perhaps we could all do the same and build up a database of true
sizes of fish
what do you think?

pics on the next reply, so they don't load as the first post one every page
 
What are you trying to get at here Wolf.
The YAAS and the FBAS publish show standards for tropical fish in their shows. One cat. is size.
They are not wild caught size charts but what is actually achieveable in the captive envoirment.
Why do we need to photograph dead fish?
 
so without further ado

what I'm getting at is
a picture is worth a thousand words
 
I see you are measuring from the tail fin, fish measurments as a rule are taken from the snout to the caudal peduncle.

But to be honest who really cares what sizes they publish. Its good to see what sizes people actually have there fish at when I lost an AT a couple of weeks ago I measured it and was suprised at just how big it was I thought it was about 4" but it was almost 7" wish I had a pic now. I know alot of people who measure there fish when they die good thread wolf mate.
 
Good idea Wolf, id much prefer seeing a photo as evidense then reading it in an out-dated book anyday.

I often quote total length (T/L) as a size for a fish rather than the scientific measurement,
this is because as a hobbyist we need to know the full length on the fish.
for instance my Adonis pleco (A.Adonis) had a 6 inch body but to the tip of the tail it measured almost twice that.
that is something that should always be taken into account when judging tank sizes.

also
showing a pic that includes the measure from the tail, allows scientific types to draw a line from the caudal peduncle
and deduct the tail for their measurement.
 
You would need to list other information about the fish, specifically thinking age here, so it gives an understanding of whether the fish was an "adult" or not.

I can understand why this would be useful :) its often difficult to appreciate size when its just a number talked about. Actually seeing it works well :)
 
hmm looks like fin rot to me
the ragged fins are due to the other inhabitants having a nibble after death.
the point is not why this fish died, the point is pictures against a measure.
