Zoogeneticus Quitzoensis

[dwarfgourami]

I am a little tempted by this fish but confused by the divergent advice given. In the Baensch atlas it says they need between 25-28C and are likely to suffer from fish tuberculosis if the temperature goes under this. The goodeid web site I found, on the other hand, claims that they will get fish TB if the temperature goes above 22C for any length of time. Clearly, they can't both be right. I am inclined to believe the web site, as its creators may well have kept the fish, whereas Dr Baensch can have hardly have kept all the species listed in all those 4 volumes. Besides, with a few exceptions (such as the Ataeniobus toweri), most goodeids do seem to like it cooler. But if anyone has any first-, or indeed second-hand experience, I would be grateful.

how about this. Screw the guides. Tuberculosis shouldn't be affected by temperature.

As far as I know TB isn't caused by temperature. Temperature can effect the immune system but not cause a disease. TB is fairly rare and I am not sure why they would say it is caused by high temperature. I have read that most goodeids like to have the temperature at a slightly lower than normal for most tropical species.

I don't suppose they mean the fish TB will be caused by the wrong temperature, merely that the fish will br more susceptible to it. And the one thing they all seem to agree on is that the zoogeneticus are quite susceptible to TB anyway. Which makes it particularly vital to know which particular conditions they are going to dislike. Most goodeids like cooler temperatures, but there are a few expections.

Fish TB is very rare, especially in freshwater fish, and it doesn't "come out of nowhere" regardless of ambient temperature. It's a bacterium that needs to be caught from another fish. So I think the temperature / TB relationship is probably dubious. A quick look at Fishbase suggests a temperature in the mid to high 20s, so I'd go with that based on their natural habitat.

Mind you, they do suggest a maximum pH of 7.19999980926514; make sure you don't go above that!

See my comment above- I fully appreciate that you cannot catch a bacterium from anything other than contact with said bacterium. Still, unfavourable conditions might make you more susceptible to a bacterium, also said bacterium might be more frequently present among certain fish populations if they happen to be particularly susceptible= provide favourable growing+ spreading conditions.

No question. I just don't think this is a big deal. A lot of aquarists apply "Fish TB" to all kinds of bacterial diseases with broadly similar symptoms. I wonder how many of them actually autopsy their fish? Or look at blood or tissue samples? Not many. Take Dwarf Gouramis -- how often to people say they died from Fish TB?

If it were me, I'd keep them at 22 C and see how they go. If it's too cold, they'll get whitespot, which is easily cured and they you could raise the temp to 25 or whatever.

Thanks, makes sense, I might go for it.
