Urgent Loach Emergency!

[CoolWater]

I have never had a emergency before, so I am panicking like hell knows what!

It is my common weather loach. His back end keeps rising up and remaining high.
This may not make sense to people who have not kept a weather loach before.

Please can someone tell me what is wrong with him. Is he going to be okay? Is there anything I can do to bring his posture back to normal?

I can not describe any better than, his back end it raised all the time, which he has never done before, and it is unnatural.

Please, help.
Thank you.

Can you post stats in ammonia,nitrite,nitrate,and ph, has he darkened in colour or gone pale, do you mean his spine is bent, don't know quite what you mean, is he bending into a s shape.

His okay! For some reason when i went to scoop him out into a q-tank to get a better look at him, he swam off just fine, and has not bent his back since!?

No no, he was laying the right way up on the substrate, but his backside was sticking upwards, not verticaly, but crooked upwards.
No change in colour and he is in a year old established tank, though i do not have any test kits with me for exact stats.

I am guessing he was maybe in a deep sleep..?
Anyone else have an explanation?

It sounds like a bacterial infection as my plec did that and died, what do you feed the fish, i would put some shelled peas in for him, and issolate him and get him on a bacterial med, he's not right.
Plus as he lost weight and is his breathing heavy.

I feed the loaches (there are two) tetrafin flakes, plecochips and recently i have tryed them with bloodworms.
He is not breathing heavy, and although he has not lost any weight, he is not as fat as his other loach partner.

The only q-tank i have is a 2.5 gallon, which is not suitable anything long term really, let alone a 4.5 inch fish!

He only did this once when i reported it. Are there any other signs i should look out for?

Bent spine and wasting away, check for when he goes to the toilet as well, and if he bloats up, and colour changes.

This sounds like a minior swim bladder problem. Usually these result from another cause, the most common of which is constipation which causes pressure on the swim bladder. the next most common cause is an internal infection resulting in the same thing. if the problem has gone away and doesn't return, then the odds are good it was constipation and it has passed (excuse the pun).
