One of my small three bar indo datnoid is kind of sick. He was good at the morning and ate well, but in the noon I found it swimming bowing the head downside in the middle of tank. They have never swum in the middle of the tank before at the daytime. They always swim at the bottom and are shy to come out when I'm near. It was bit slow at swimming too, that I can even get my hand close to it in the water. Other one was bit of chasing it and knocking. I put some dry shrimps then, but this sick guy didn't eat, while other was eating. Then I add some salt to the tank and in the evening both ate shrimp well. However again now in the dusk it was much worse again and the other guy was seriously knocking this guy and it was not defending or swimming away. So I now get it separated till it will get better. I don't know what is wrong, he seems breathing very well, but just keep bowing the head downside and swims everywhere in the new apartment like a sick one. Normally they are shy and hide whenever they see me.
Is this something I should consider seriously? Hope your help. They are small than 2.5".
