DATNOIDES: Please help. Reddened pectoral fin joints? Funny behavior

[Lima_dat_alone]

I have two old datnoides. I recently added a bubble stone to my tank and thought they were just acting funny due to the extra O2, as one was playing in the bubbles and hiding in them constantly, but now I'm not so sure.

One lays on the bottom, in the corner, in an indentation he dug. He ventures out for swims and food, but his swimming seems to require a little bit more effort than usual.

The other, just seems to float at a 45 degree angle near the surface. HE would not eat tonight, but did have a bowl movement.

I have administered two oral doses of geltek ultra cure BX, a nitrofurazone antibiotic to the first fish. And I administered one does manually to the second fish tonight.

I have included pictures of the fish, and you can see the reddened joint on the first fish.

Please help me diagnose this, so I may proceed with injections of antibiotics if necessary.


Fish 1

Fish 2

(The damaged eye was from a bout of popeye several years ago.)

I can provide any further information necessary, or more pictures or video.

Do you think it may be haemorrhagic septicaemia? Have you thought about treating the tank with a broad spectrum antibiotic such as maracyn and maracyn 2 ?

Any chance of chemical contamination getting in the water somehow?
Fumes of some sort pumped in by the air-pump?
If either of these cases are likely them maybe a 50% emergency water change may help. Also remove anything you've recently added to the tank which coincides with the illness.

Good luck.

I had an exam done. There was a large amount of a small coxii shaped bacteria. I've got baytril injections. I hope they come through.

I'll keep my fingers crossed for you, I hope they make it

Any more pics of this?
Is there a greyish white film over their bodies? Or are they scraping against anything in the tanks?

There's a slight film over the "nose" of the dark fish you can see in the picture. They are not rubbing against anything. The dark fish swims in circles still but, is doing it more vigorously than before the first injection. The lighter fish still lays still at the bottom. They do not breathe laboriously.
