sick CPD

[jonathan and Karen]

one of my cpds is spazzing out so much He's the one I've been having issues with for a while he is swimming very funny very similar to like a snake or a detritus worm in the water column he ate a little bit he was just on a full treatment of the bacterial and the paraclense not that long ago and was doing really really good. when I first got this fish the store had been having a really hard time keeping them alive for more than 3 days I got 7 out of 9 that lasted 2 weeks in the store I've been losing them every few months or so and it's almost been a year or at least 10 month. l what do you think you could be? is there anything I should try to do it's just today I've had issues I don't know where else to go sorry for bothering you and thank you for any answers. he did have a bacterial infection or some sort of infection probably a week ago which is why I started the treatment do you think it's old age or hit something in the tank. all the other fish are doing amazingly including fry that are teeny tiny like maybe a few weeks old in the exact same tank.

there was nothing left physically wrong with the fish mine is a few scales pulled up which that was what the fungus did if anyone wants to know it was some white fungus that ripped away the scales of the fish and there's a slight drop in the color He's not nearly as active I don't know what to do. if it be anything it would be neurological is what it feels like is this something they'll recover from or is it a death sentence

have you treated for internal parasites or worms? I see that you used paraclense but have you tried API General Cure? Whats your water paramters?

my parameters should be just fine because I just did a large water change of about 50% yesterday That's a normal amount for me anyway so don't see how there be anything on that front and I did the bacterial that is in the aquarium co-op quarantine trio

[jonathan and Karen]

my water is softer with the pH around 7.5 if i remember correctly and one thing that's also the note all the other fish in the tank today for some reason are more aggressive and more active The temperature is around 76 according to the thermometer I cannot currently test the other parameters at this moment
