40 Gallon Tank Sick Dojo, bacterial?

40 Gallon Freshwater, Heavily planted, 6 month cycled (started off with filter media and substrate from a longer established tank to begin with)
tanks in the household: moms 2 and my 4
ammonia: 0
nitrites: 0
nitrates: 5ppm
temp: 72f
PH: 7 to slightly lower than that

stocked with;
1 striped talking catfish
2 golden weather loaches
5 tiger barbs
1 hillstream loach
1 bristlenose pleco
3 endlers
2 sterbi cories (hatched from accidental egg batches from a different tank)
1 panda Gara
5 cherry barbs (have always gotten along with these tiger barbs, it's weird)

Hi yall, my mother's golden weather loach has suddenly come down with some weird. lumps and bumps, and some redness. Said loach and it's buddy loach have been in the tank for a few months. This loach has had swim blatter troubles before but they've been under control. The other loach is perfectly healthy and happy and thick.

Sickly loach now has a few lumps that are the same color as his gold as well as an irritated red area, a swollen and red (I'm assuming) anus, and red gills. He's also been chilling upside down but that's not entirely a new thing for him when he's not feeling great. Photos attatched.

He is currently in a quarantine tank with melafix, aquarium salt, and some cattapa leaves. This is all I've had stocked up and it's currently late.


Does he have a chance at survival? What should I get at petco/smart tomorrow for him? Is this something he could have always had?

Everyone else in the tank is doing really well and aren't showing signs of stress.

Thank you all!

 

As of this morning he's still alive. I am currently at work so my mom did the water change/re-adding the salt and melafix I suggested.

She says he looks less read over all and that his vent looks less irritated than it does above. Once I get home I'll grab new pictures.

I had thought he was dead when I checked on him this morning before running to work but he's just being very still and sluggish.

We're going to give him so frozen blood worms to see if he eats later tonight.

 

Another update: I've gotten home and he looks much better than he did last night. He's swimming a bit and resting right-side up on the bottom of the tank instead of upside down at the top.

We're adding some epson salt to the mix because while I was at work I found that this is probably steming from a prolapsed anus, possibly from overeating possible from something he already has.

His vent is less swollen but more red but the red rash is significantly less angry and I don't see all the lumps now.

I'll keep this post updated because all the dead end "sick loach HELPPp" posts drove me mad while digging for this little dude.

ps: the water is now tinted with tannins but not enough to hide the red rash.

 

He passed this morning

 

I’m so sorry to hear about your loach! I was hoping for a happy outcome. My loach seems to have the same issue. He has a couple of lumps and an abscess on one of the lumps. I treated him with some kanaplex and metroplex And it seems to have calmed the irritation. But the lumps are still in there. I’m going to add a little bit of salt to the quarantine tank and see if that works. Thank you for this post is it gave me a little bit more idea.
