Fancy Goldfish Sick- White Spots and Red Streaks on Fins

We've had a fancy goldfish and a small catfish in a 10 gallon tank for a few years now and recently (April 4) added 4 ghost shrimp, 2 mollys, and 1 platy to the same tank. We noticed the platy was nipping at the goldfish, so we removed it and gave it away to a friend. All seemed to be going well after that, but last week we noticed the goldfish exhibiting what we thought were swim bladder issues. We tried to address that with fasting, but over the few days, we noticed a lot of white dots on the fins pop up as well as red streaks. As of today he's mainly been gasping towards the top of the bowl we put him in (removed him from the 10 gal tank 2 nights ago) Any hope for saving this guy!? Not sure about the water parameters for the tank we have our fish in. Haven't seen anything unusual with the others but do we need to treat them with anything or change water? Any insights appreciated! Picture of the sick goldfish and our tank attached.

 

Hi! It looks like he's got ich. It can be treated with medication like Ich-X, or with a high enough dose of aquarium salt. (I'm not a goldfish expert so I can't say how much, they can tolerate a lot of salt.) But judging by the history you gave, it sounds like this is a result of stress. It could be water parameters, tankmates, a disease or parasite brought in on the tankmates, or something internal. My guess is that adding the tankmates caused an ammonia spike, which stressed him out. The gasping and redness are likely ammonia poisoning. He's in a very small bowl, so unless you've been changing the water in that bowl multiple times a day, ammonia is building up in there like crazy. I know you want to keep him separate from his tankmates for their sake, but keeping him in that bowl is very likely making him much worse. I'd put him back in the tank.

I know it's not easy to get stuff right now, but a test kit will go a long way to helping you figure out what's going on. Most people consider a good test kit to be nearly essential to aquarium ownership. They're an invaluable tool. For the time being, if your nearest pet store is still open, you can take some tank water in and ask them to do a test, just about every store will test your water for free. (Just make sure to practice social distancing while you're doing that!)

Thanks for your help and tips on testing the water! Just put the goldy back in the tank (was not thinking about the ammonia spikes!). Will definitely look into getting Ich X, soon.

 

Goldfish shouldn't be with barely any other fish other than their own kind. I would get him a new tank or even rehome him asap, those fish are bound to bully him to death. He has ich, which you can treat by raising the temp and adding aquarium salt or an ich medication. I would use Minn Finn if you want to go for bottle medication. Do water changes once a day on your tank, the water parameters are definitely off. He's a beautiful butterlfy, I hope he makes it.

 

What everyone else said Is good advise, I would add some things, which is to get him a 20 gallon or 30 (if you want him to have a tank mate) also get an air stone and something to power it if you do keep him in a bowl. I recommend the largest bowl you have or a bin works great too.
Hope he gets better.
