Oxygen Levels
#1
Just found out what is wrong with my Dwarf Gourami, he is starved of oxygen, LFS checked the levels for me and they came out at 2mgll and according to them it should be between 6/8mgll. I didn’t register with me because none of my other fish seem to be effected, the thing is as I said before I chopped down my heavily planted tank pretty drastic, that’s the only thing altered in my tank.

The thing is now how do I get it back up quickly, I have done a 25% water change but as yet no change, I have a good supply of air bubbles and a vigorous surface agitation, I have read that leaving the lights on for over 16hrs will help ????

What do the learned members on this forum suggest I do, please any comments will be greatly appreciated.

My tank has a well fit glass top, should I remove this?

Regards Bob

Sorry Bob, but that is a weird advise.
(Dwarf) Gouramis are "equipped" with a second breathingsystem cause they live in stagnant waters that are very low on oxygen.

So for any other fish I would understand, but this can't be the issue with a gourami at all.

I concur with DD.

If the O2 concentration really is 2mg/l, then any non-labyrinth fish in the tank (i.e. those without DD's 'second breathing system') should be dead or dying. Is that the case*?  If not, I suggest that the shop's oxygen test is either no longer fit for purpose, assuming it was at one time, or that it was conducted improperly. 


* edit : I've just seen that it isn't.

The fish has an issue, not the water.

I am glad you you said that DD, because I have been convinced that since I saw Berts mate on the bottom of the tank dead I believe that ALL gouramies have a genetic gene that might cause unexplained deaths, I wonder if there are any fish keepers out there that have had fish just die for no reason that can be explained.
He is really acting as though he is sick, but apart from his laboured breathing, and lethargic manner he looks OK!!! and of course his lack of appetite.
DD is right Bert has an issue, BUT what is it ?????????

The reason I ever joined the UK forum were dead DG's in Hollamd by an unknown cause.

Ian @plankton was the one that welcomed me and pointed me to Dwarf Gourami Disease. A virus that we have "bred into" this beautiful fishspecies. It is disastrous.

Yes, the iridovirus that they have is due to the way they are bred and raised in a cocktail of meds.
This makes their immune systems unable to cope with normal problems.
I did ask on your other thread about the temp, as I thought it may be that he may just be taking in lots of oxygen to cope with it.
If at first you don't succeed....

Enjoy your fish, shrimps and snails!

Thanks for all your replies but I am sorry to say that Bert my D/G passed away peacefully during the night.

I couldn’t see anything wrong with him, no lifting scales, no slime, gills nice and reddish, bright eyes must say he looked as good dead as he did alive.

My two angels are being re-homed today so I have to decide what to have next, I fancied fancy guppies but after reading up on them, and all the horror stories of keeping them alive for any length of time in a community tank I don’t know. I can not seem to raise the really soft water I have, so maybe should keep to small fish that like soft water conditions, the 5 Cardinals I am left with are doing fine, so maybe something of that ilk, something with a lot of colour, and panache LOL
