nitrate has nothing to do with it many people with big fish are lucky to keep their nitrates below 100ppm

the nitrire is probably the problem

also what is the ph it chould be to low i have seen many NGT being stressed out out and acting the same way due to the ph being to low

ph 7.0-8.0 is good for NGT

also a 10g tank thats way to small

you also state your NGTs how many do you have in the 10g


Ok, to lower the nitrite I will try to do twice a week water changes of about 30% instead of the usual 50% weekly water changes. Hopefully that will solve the problem.

With regards to the tank size, it is a quarantine/grow out tank. Until they show they are "confident" enough, they're would have to stay in the 10G. They were in my 60G before I moved them to the 10G. They were the same way as they are now. They were playing dead before and they rarely ate because they don't come out a lot and just hang on their side. Come to think of it, I have never seen my NGTs eat... I decided to move them to the 10G so that there won't be too much competition for food.

I will check the pH later if more information can be gained from it. It will be posted later.

In the 10G, I currently have two 2.5 inch NGTs and one 1.5 inch Indo datnoid. The indo seems fine and it swims around. It also feeds in the guppies that I feed it. Once in a while, it also becomes stable.
 
because you have a nitrite reading your tank is not properly cycled and dats don't like immature tanks,how long has the tank been set up? i always practise fishless cycling nowadays it's alot less trouble,keep up with the water changes and with the extra hidey holes they should be fine
 
^Tank has been up for 8 months and I used media that was previously in another penguin 250.
By the way, water change hasn't been done. It will probably be done in the next couple of hours.
 
I did a 30% water change on the 10G then I tested NO2 and pH after. NO2 is currently at 0.05ppm and ph is 7.8.

To address the size part, I decided to move the 2 NGTs back to the 60G. By the way I also did a 30% water change on the 60G and I didn't bother testing the water parameters. All my fishes in the 60G are stable and there is always good competition for food. Bigger ones get more and the smaller ones get less or until the big ones are done eating. By the way even the silvers datnoids are now fully stable after close to 2 months of being totally unstable. All of the fishes in the 60G are now on the market bought blue anchovy diet which runs about $1.77/lb. I thinks that is worth mentioning because that will definitely save me a lot of money in the long run.

Anyways back to the story. I moved the 2 NGTs to the 60G. After about half an hour, I checked on them and sure enough, they are slowly starting to color up. Although they are now coloring up all they do is hide wherever they can. At least that is a step in the right direction. Hopefully I will catch a glimpse of them eating which I highly doubt. These two NGTs are in the bottom of the ladder when it comes to size. The smallest in the tank, an indo datnoid is 2nd in command next to a managuense.

On a side note 1.5 inch Indo datnoid is all alone in the 10G. It will probably have a handful of companions when I get feeder gupppies sometime tomorrow.

So yeah, that's the story and I guess the NGTs will stay in the 10G from here on.
