When using Furan 2, follow the instructions on the box and redose after a water change. The discus is stressed and the white feces can be hex, which is opportunistic when a fish is stressed.
General Cure won't really help with the external issue.
Have you aged your water or reduced the percentage? If these things along with salt don't work then I would use the Furan 2.
Excellent idea on the Brute! During the summer, my water ages without the aid of a heater or air stone. During the winter when the water is colder, I use both.
I'm not sure where you live, but most LFS carry Furan 2, although it's much more expensive than online. Also, you can use the salt and they say it won't hurt your bio.
Thanks. Wouldnt be able to get rid of all the salt in the tank without multiple water changes. I ordered 3 boxes on prime and should be here tuesday. It will give me 2 days to slowly adjust the temp from 88 back down to 82.
The circle on the back fin has dissapeared with salt but the main 2 white circles on his body look like they are turning red in the center
Also 2 of the discus continue not to eat. The guy in the pics with the 2 white spots still has a full appetite tho
I wish there was more to say, but I think you were unfortunate to receive sick fish from a bad supplier. Have you called Discus Madness about this? They may have some additional ideas... I seller who cares about their reputation will also be there after the sale. I'm seeing very mixed reviews about them...
I wouldn't approach them as challenging them, just call and ask for advise. This will make it easier to communicate with them and they may actually agree with our discussion here.
To be honest, this could be something as simple as aging your water or other subtle changes. I'm just a little stumped and it's easy to make an assumption when viewing a photo of a fish that is obviously a little stunted. I've never had to deal with issues like this so I can only make recommendations based on what I've seen others do and hope my memory serves me well.
Dissolved gasses are always present in pressurized water systems whether ph changes or not. As these gasses expand and evaporate there are chemical reactions to the water and this can cause stress to discus. Adding stress to a less than perfectly healthy discus can cause their system to become more susceptible to things that would not not normally be an issue. For the most part, most people can do 25%-30% WC from tap with no side effects. More can be stressful. During the summer time, I can do 50% straight from tap - during winter only 25%...
Yes and yes!!
Furan will kill off gram positive and gram negative bacteria which means your biofilter will take a hit as well. You will have to be diligent with you water change schedule post treatment so you don't get ammonia & nitrite spikes
