Cory catfish is twitching

[RainGamma]

That's so weird. Video?

I will try to get one, that’s the dead catfish that did it.

not sure why they are losing their barbels @JuiceBox52
it’s kinda hard taking A video but I will try

 

[RainGamma]

Caught these two doing it, not on video but I will try. I am doing 75% waterchanges everyday

I swear this is petcos fault.. I bought these 3 little Cory catfish and they all seem sick. This happened after I bought them. My other big Corys are fine they probably fought whatever this is off.. and so is my betta

Have you added anything to the tank? I would do what Colin would probably advise which would be wipe down the glass and clean the substrate along with a 75 - 90% water change

the fish in the last 3 pictures are covered in excess mucous and one looks like it has a problem with its mouth (possibly Columnaris).

I have no idea what has been said previously but the excess mucous is either poor water quality, chemicals in the water or an external protozoan infection (Costia, Chilodonella, Trichodina).

2 heaped tablespoons of salt per 20 litres, and water changes.

Any salt is okay? Also I never treated any illness before

rock salt, swimming pool salt, aquarium salt, its all the same stuff.

Okay, how long should I wait Till I change the water and how long should I do this for

I thought Corys didn’t like salt I really don’t know what else to do so I will do as u say, but I could also get meds from my fish store if needed

 

[RainGamma]

also I don’t have a seperate tank, I’m guessing u want me to add salt to my main tank?

Colin has recommended the lower dose because cories are in the scaleless range. Yes salt is fine but make sure you do the 2 tablespoons to every 20litres. That salt is perfect. When you water change make sure to add what you take it or you will end up diluting the salt out.

Ok so I have 20 gallons, so like 8 scoops.

20 gallons is 75 litres, I would do 7 to be on the safe side.
