tl;dr even with the best filtration, you’ll probably still need to increase water changes to keep the goldfish.

*Typically if you have measurable nitrates, the ammonia cycle is where it should be.

Just a quick primer: there are specific bacteria that oxidize each form of nitrogen into less toxic molecules. Nitrosomonas oxidizes the ammonia into nitrite. Nitrobacter oxidizes the nitrite into nitrate.

Its likely that the necessary bacteria is healthy and in sufficient numbers, but filtration/flow is lacking – and this is the key point – for the bio-load in your setup. Water changes will be the only fix here.

I’d test for nitrite and ammonia just to rule out loss of one or more nitrifying bacteria. If you have measurable ammonia, you could step up water changes (frequency or volume or both), or remove the grubby, stinky goldfish.

Back in the 90’s, the local aquarium hobby store where I worked had around 1k feeder comets in a 55gal tank in the back. It was plumbed to a massive wet/dry sump that was full of “bio-balls” (the height of filter technology at the time) and pumped by a 1.5HP pool pump. IIRC, the total water volume was over 125gal. We had to change the water in that system every week to keep the water clear and clean.

Maybe its snobby of me, but it never seemed worth it to me to keep goldfish. I prefer Mollies for hardy fish, and they have more personality for my $.

Bonus: now I live in Central America, and swordtails and mollies nibble my toes when I swim in the rivers and waterfalls here! I would love to open a hobby store, but not sure if the government here allows it.

As the other commenter posted, a 20g just isn’t big enough to support them. But the fish in the existing 20 sure would appreciate if the goldies moved!

I worked at a different shop.

Poor water quality is the most common cause of color change in goldfish.

You mention 50% water changes. If you really want to keep these goldfish, you probably need to step up to 80% water changes.

Goldfish are big polluters. In a 20gal tank, they are likely too much bio-load for that tiny bubble filter you have (unless there’s another filter I’m missing) to keep up with, and all of the fish are going to suffer.

Remember: the nitrifying bacteria that reduce harmful ammonia and nitrite to relatively less harmful nitrate only live on the surfaces of substrate in your aquarium. That means that your filtering capacity is limited by how much water passes through it, and your little filter is low-flow and small.

Unless you can add significantly more filter capacity (underground filter that pulls water through the gravel, or an external filter that pumps water through cartridges or high surface area media – which still may not keep up with these dirty fish), my recommendation would be to remove the goldfish.

All that aside, goldfish can also change color when they are growing very quickly. They will eat as much as you give them, and if they get more than they need, they will grow very quickly. There used to be a myth that they grow to the size of their environment, but I’ve seen them in a 55gal and remain one inch when fed sparingly, and also have seen them grow to six inches in a 10gal.

Goldfish are good starter fish because they jump-start the ammonia cycle and they’re relatively hardy. I don’t like them as long term community members because they’re dirty and can increase the workload for new aquarists, causing stress for other fishes and discouraging beginners from the hobby.

Edit: typos

Not a fix, but a workaround I use when symbols and punctuation are treated this way: I use lowercase letters to precede folder names to get the sort I want.

aFolder1
bFolder2

Not elegant, but it works in your case. You could also try other file managers, like Thunar to see if they manage sorting differently

s38b35M5, 12 days ago

Yeah, that sounds like a better long-term solution for you. Once you change your workflow, you shouldn’t have to do it again anyway!

If you dare, you can automated it with some simple scripting. If I had more than 20 or 30, I’d probably go that route.

s38b35M5, 12 days ago (edited 10 days ago)

I’d use the find command piped to mv and play with some empty test folders first. I’m not familiar with Nemo, though I’ve used it for a short while. I’ve never tried the bulk renaming features if they exist.

Depending in how much variation you have in the preceding underscores, REGEX may be useful, but if its just a lot of single underscores you can easily trim them with a single version of the script.

Edit: corrected second command typo. I think there’s a rename command I haven’t used in ages that may have args to help here too, but I’m away from the PC

The capitalism-or-death crowd will still likely use it as an example and point to the shrimp idea as a miscalculated attempt to help the masses that failed because of the greed of the poors.

s38b35M5, 10 days ago

That makes me happy.

I can’t take credit though; its a frequent utterance from Karl Bode. It certainly fits!

Joke’s on you, Google! I uninstalled the Play store weeks ago!

Its a real catch-22 engineered by SCOTUS to do just that, I believe. The number of cases that receive QI where the judge regretted that the way it works results in a finding that “reasonable” officers wouldn’t know just boils my blood.

Thank police unions and the justice system for making victims think settling is their best way forward. Fear of getting no justice at all after what they’ve been through is a powerful deterrent. That’s why I am glad when a well funded activist organization get behind victims (or are themselves the victim) and take it to trial.

I would be hard pressed not to accept a settlement in the neighborhood of a million dollars, as things are so effed up for workers in this economy and that would set me up for life invested properly.

Despite Dare’s documented actions of violating a plea agreement, breaking and entering, trespassing, discharging a firearm in a residential area, putting residents at risk for serious bodily harm, and being a neo-nazi, he was only fired from NJ State Police and is not facing any criminal charges or barred from future employment as a state employee or police officer.

Kid gloves…

I’m also interested in the true size comparison without the skewed size that occurs further and further from the equator when you make a flat, rectangular map from a sphere.

Now that you mention it, I think I can tell yt-dlp to give me vorbis, but it might still entail a conversion.

Good heads up. I haven’t loaded in yet as my region is experiencing power outages. Last season grind was really rough and I wanted the final level of skins at level 200 for Artemis and Aphrodite, but I didn’t care about the others, so getting to 190’s got me there and I said I’d likely not worry about the pass this season as the grind was really a slog for the past few weeks.

Actually, last month’s crew (or whatever its called) skin intrigued me for the level ups a few months later, but I ultimately let it pass as I don’t want to subscribe to a game and they often just rug-pull by selling skins in the store that I thought were exclusive in one way or another.

Edit: Can confirm I won’t be buying this pass. Possibly playing this season either. Cars, cars, cars… If I wanted that, there’s a game mode for that. Wish this game could decide what it wants to be…

s38b35M5, 16 days ago (edited 14 days ago)

Yes. the idea of scarcity/rarity is what makes my family pay for the battle pass some seasons. If the rewards of the pass aren’t enticing to us, we don’t bother. If we spend money and grind, only to see those skins for sale, it’s a betrayal of sorts.

Thx for this comment.

My main drive for self hosting is to escape data harvesting and arbitrary query limits, and to say, “I did this.” I fully expect it to be painful and not very fulfilling…

Haven’t done this yet, but this is a source I saved in response to a similar question a while back.

It might help others if you update your OP with the solution

We call those “whisker balls” in our house, but I love peanut whiskers.
