Have you tested your water?
Yes
If yes, what is your ammonia?
0 ppm
If yes, what is your nitrite?
0 ppm
If yes, what is your nitrate?
0-5 ppm, slightly above 0 but not very high
If I did not test my water...
  1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.
Do you do water changes?
Yes
What percentage of water do you change?
21-30%
How frequently do you change your water?
Every week
If I do not change my water...
  1. ...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.
Need some help, this is now the second fish I have had with this condition. The first one was a couple months ago, I have since lost that fish and now have another one showing the same symptoms, but I could not figure out what was wrong with the first one. As it progressed for the first Surinamensis it was a little bloated, his color was dull and had sub-dermal redness in the front of the face and redness/swelling at the base of his pectoral fins and along the body at the base of the dorsal fin. The fish's breathing became a little labored but otherwise their behavior seemed normal, continued to eat (at least they looked like they were trying until near the end).

The fish that is showing the symptoms now just started showing them yesterday and I hope to get some info on what it is so I can treat them before it progresses like the first one. I now have 5 Surinamensis in a 130 gallon with a couple peaceful catfish, there are no aggressive fish in the tank and all of the other fish in the tank are healthy. I’ve had them for about 2.5-3 years and nothing new has been added in over 1-1.5 years. I have added photos, the first two are from the current fish that is sick and the last two are from the first fish that had the same symptoms a couple months ago.

I use municipal water, but i don't think that is the cause, since between the first fish and now this one I have moved to a different county and no longer have the same source and I will post the water parameters below, it was tested using a master test kit (liquid test solutions), and my pH is 7.2-7.4.

Any advice is appreciated, thanks.

How often do you perform water changes weekly, bi-weekly or monthly? Also do you shake your Nitrate test bottles before testing?

I change 20-30% weekly. Yes all bottles are shaken before testing and the tubes are rinsed with tank water before adding water to test.

I suggest removing more water 50% or more each week and see if things improve.
