Goldfish with a cut?

[KatFish]

Parameters: (and please ignore the cloudy water in the tank- The nitrogen cycle got re-kicked off when my old tank leaked, and I put them in a new one, so I'm dealing with the algae bloom) 
Temp: 68*F  
Ammonia- (scarily high) at 8ppm
Nitrate- 20ppm
pH- 7.4
Nitrite- .05ppm
I have been doing 50% water changes everyday on the tank, to help fight off the algae bloom. 

Here's a question for you all- 
Can goldfish bite each other, or give each other what looks like cuts? 

Because they haven't been showing complete hostile behaviors- I don't see signs of fin damage, or them being on separate sides of the tank. 
But when I first got a close up look at Crabbe, it looked like he had a coloration spot, and I thought it was just because he was growing. 

But now with this "cut" I'm not so sure. 
I put maracyn into the tank, as well as some stress coat. 
Here's what Crabbe's "cuts" look like. 

This is the one that I think is the coloration:


And this is the one I think is the bite/cut:

 

Do I need to separate Crabbe and Goyle? 
Is there a different type of medication I can use to stop the "cut"? 
Or am I just being paranoid and this is a coloration?

I've only dealt with Tropical fish before, and my accidental owning of mystery snails- so goldfish (pun intended) dropped me into the deep end! 

Thank you so much!

I do not think its because of them fighting nor I think its a cut I believe its because of your ammonia is so high plus your nitrite which both are extremely harmful to fish. https://www.thesprucepets.com/treat-fish-for-ammonia-burns-2925396 Most likely ammonia burns

Thank you! 
this is a really helpful article!

Tank update- 
Thank you so much @DiscusLover for the article! I did a big water change on my tank, and that helped out a ton. 
The water is already so much clearer! 

Here's a picture of the tank in general- and yes, I stuffed a basil plant in my HOB filter 🤣, I have seeds in the terracotta pot as an experiment- (but honestly, they came from a kit that had an expiration date from like... 4 years ago, so... I don't exactly have any hopes of the seeds survival.) 

Also- I realized that (before I added the basil plant) my HOB's filter had a carbon thingy in it. sighs  
So am I going to have to redose my tank? It's only been a few minutes since I put in the dose. 
Advice would be appreciated.

Yea your tank is way to small to fit 2 goldfish. You do know how big they get right?

What would be doing with ammonia at 8ppm nitrite at 0.5 is 50% water changes twice a day and you can dose seachem prime up to 5times the recommended dose in emergency to help detoxify any ammonia or nitrites ammonia at that will kill your fish is water levels always that low or is it because your doing a water change if it is I would recommend filling you tank up  to the top  and I would recommend using a canister filter with goldfish I use a fluval 307external canister filter and a ziss 300f bubble filter for my 12 in fish that works well for me not detectable ammonia or nitrites and low nitrate 10ppm in short term large twice daily water changes till your ammonia and nitrite constantly stay at zero is what needed @Swampbones

Follow Colu's advice. Ammonia and Nitrite can and will kill the fish. Daily (or twice daily dechlorinated water changes will help. But ultimately you want both at zero at all times. You should feed VERY lightly if at all until levels get in check.

Yes. My family and I are well aware. We live in an 18x60 mobile home in a mobile home park. 
when the county tax rate for where I live is no longer 8.5% on major assets like a home- maybe then we actually qualify for a loan to buy a real home with a backyard for me to give the Comet Goldfish the space they deserve. 

I appreciate your advice, but this comment was unnecessary.

I currently have 3 sponge filters and a HOB that came with the original 10g kit that claims to filter up to 20g. 
But I am doing daily water changes. 

The current reason as for why I don't have the water all the way to the top, is because it seems like the HOB overflows with the cartridge it recommends you use. 
The water goes right up to the very tippy top of the HOB- and this is before me putting in the basil plant.

I put in the plant to help block the water flow, and give the natural nitrogen cycle help like ACO's guides and videos recommend with live plants. Same thing with the terracotta pot. It has seeds growing inside of it, soaking up the water through the pot. 
Once my local garden center opens back up- because they close up once august ends- I will buy another terracotta pot, and then be able to raise the water level. 

I hope by that time however, I have been able to think of a better way to work on the aquaponics set up, for the tank, to make this a non-issue.
Thank you for your advice on the medication- I couldn't remember what the name of the product was I was looking for, it's in my shopping list to get once my family gets some more money.

For now, it's twice daily water changes, and active monitoring.

I would also add some aquarium salt 1 table for 1 gallons will provent methemoglobin toxicity by blocking nitrite adsorption though the fish Gill's and the salt will help to relieve stress on your fish kidneys caused by ammonia poisoning @Swampbones

Should I pre-dissolve it in dechlorinated water or just let it into the tank? 
 

[Colu]

I deslove salt in warm dechlorinated water then add it to the tank
