my 3 Colisa Lalia have died but not all at same time

the first about 3 weeks ago i put it down to natural causes
the second about 1 week ago and the last of them was today

my question:

are they a weak strain of fish and prone to disease or do i have a problem in my tank

no other fish has been affected or shows signs of illness

but none of the dead fish showed any signs of illness either

water parameters havnt changed as thats one thing i have trying to keep on top off

although they are not ideal values they have been stable

another question is what should the average lifespan of these fish be?

Colisa lalia have a poor reputation at the moment due to an iridovirus that has infected the breeding ponds in the Far East and shortens their lifespan. If you want to keep them, then it's a case of trying to source quality stock from a local breeder.

I agree with Eyrie; I bought a superb looking pair (although I knew that there would be a fair chance they would have the viral problem). They only survived for two to three weeks and looked perfectly healthy to the end.
Maybe try to find someone breeding some from uninfected stock?

Cheers, Mark

thanks for that it has put my mind at rest a bit

is the virus contained to the Colisa Lalia or does it spread through the rest of the gourami family

Haven't heard that it affects other species, but willing to be corrected.

Just to correct the species name, it's currently Trichogaster lalius.

Is anyone in the AAGB currently breeding it perhaps?

Any idea why the second element of the name has changed from "lalia" to "lalius"?

It's because of the latin grammar, they just put the species name into a correct declension based on the genus name.
Colisa is a feminine noun so the species name had to correlate with it. Now it's changed to Trichogaster, which is a masculine pronoun so, they had to change lalia to lalius, feminine form to masculine form.

Haven't been near Latin since I left school, but that's very clear - thanks /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

For me Latin at school is also a long time ago, but when I read the following article Trichogaster is feminine.
The species name lalius is regarded as a noun, so it's always lalius whatever gender of the genus.
Feel free to correct me if I'm wrong. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

So are u saying it should have been Colisa lalius all along?
That doesn't sound right to me, but I wouldn't bet any substantial sum of money on my knowledge of latin /blush.gif" style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" />

I can't open the article but I'm pretty sure that the -er ending means a masculine noun.

This makes sense.

I think you're right Henri and it was even described with that name.
