OK I was worried. The other one had some sort of internal bleeding. When I pulled it our of the water there were red lines showing through this skin that's why I think it is some kind of internal bleeding. I have an arowana. Jack dempsey 3 peacock bass and a pleco the catfish and peacock were relatively the same size. Arowana is about 6 inches long and the jd is about 6 inches long.Yes swimming upward is normal even if they do it for hours. What caused the other to die? If the tank is too warm that could cause them to die. Also the fish are very calm and can easily be picked on. What tankmates do they have?
I actually don't know. I've never gotten or used a kit. I do weekly water changes of 30-40 gallons and my water is pretty clear so I've never bothered to get one. This is the first fish in my tank to die and not be eaten. I'll look into getting one and test my water when I get a chance.Red streaks and redness on the body, fins, head here and there often indicate hemorrhagic septicemia, usually the last step of some other illness. It's a bacterial infection, not bleeding.
What are your water parameters and what kit do you use?

It is very highly advisable to use a liquid test kit, e.g., API Master kit. I don't want to come off pushy or arrogant, but there is pretty much no way around it. If one wants to keep fish, they must have such a kit. It's only $20 and good for hundreds of tests.I actually don't know. I've never gotten or used a kit.

Got my test kit. Went to pets mart and bought this kit for 26 bucks not sure if that's a good price. But what ever.It is very highly advisable to use a liquid test kit, e.g., API Master kit.

WCs and water clarity are not something to go by. Your clear water may be laced with plenty of poisons and toxins and kills fish while the murky, muddy water in a nearby body of water is pristine and fish are thriving in it.
