Made An Interesting Discovery By Accident!

Hello everyone,

Made a curious discovery,

PICTURES ENCLOSED, PLEASE REFER

My friend gave me a 1 gallon goldfish tank ( with 2 goldfishes ) to lookafter as he was going away on a foreign holiday

3 weeks back, I did a 100% water change. There was a sheet of glass in the aquarium, the same size as the bottom of the tank. That day, I was in a hurry so, I keept the glass sheet tilted against the side of the aquarium so that the tank divided into two portions. I only feed them the plant chara ( to avoid bloating)

I was very busy these weeks and did not care much. About 2 weeks after water change, I checked the tank and lo and behold, the water was crystal clear. Normally the water used to get cloudy afrer 5 days ( no filter or air bubbler in this tank ). Actually, there is a bubbler, but it won't work.

The curious stuff is, it seems that all the waste is neatly deposited in the part of the tank enclosed by the glass sheet. It occupies maybe 1/3 of the tank.

3 weeks, no water change, no cloudy water, only water refills ( it is summer here in ) and 100 % natural filtartion and crystal clear water.

Still haven't the foggiest idea how this happens, the goldfish live in the other side and have no acess to the encloses region. The only way the waste could have got there is through the small gap on either side of tilted glass ( about .3 mm wide )

The part of tank where the fish live has no waste deposit. I do not think the goldfish could possibly carry waste in their mouth and spit it through the .3mm gap ( for there is waste deposited throughout the middle of the enclosed region)
On curious thing is that there seems to be a heap of waste on the farthest left corner of the enclosed region.

This is a very good natural filtration way.

But still I haven't figured out how this works.

Anybody had similar experiences?
Maybe it has got do so something with osmosis, if so, could anyone please explain?

Looking forward towards hearing from you all.
Awaiting your responses.

The only thing I can think of is with the positioning of the glass and gap ether side the fish movement is naturally causing a current and pushing everything light to that one spot, they're in a small space so movement is more than if they were in a 10gal

Tell your friend how to keep fish the right way, those two goldfish need at least a 30 gallon aquarium with a filter a heater (Because goldfish still need a heater to keep a consistent temperature) and a bubbler.

I agree with the above, minus the heater. Goldfish are not tropical and prefer cooler water, and none of my tanks that house goldfish have a heater. They can tolerate very low temperatures and are frequently housed outside in cool environments with no ill effect.
Goldfish do, however, require very clean water which will require water changes of large amounts. Please tell your friend that his goldfish would be much happier in a proper setup and can live more than ten years.

Agreed. Goldfish do indeed prefer cold water.
I do disagree with the lifespan though. They can live anywhere from 5-45 years, though 5-10 is more common.

OP, this has happened to me before. I once tried to introduce some plants to my brackish 10 gallon. The inhabitants (fiddler crabs) ripped them up after about 3 weeks, but since then the water has been perfectly clear (I added some brackish water plants).

I like having a heater in a goldfish tank just so I can keep a consistent water temperature I normally keep goldfish tanks at about 73 degrees Fahrenheit

Its called brownian diffusion
Thanks, I do agree

Thanks for the quick response

I don’t know but I am not receiving any notification via mail when someone is posting in the forum. It is quite frustrating. Also to see this thread, I had to search it in fish lore website. In my content, it is vanished. Anyone know how to fix this?

I’ll send a screenshot to my friend right away, maybe that will change his mind.

Do you guys think this method can be used to keep small tanks clean?

Although the waste is behind the glass it's still in the tank, so you'd still need to perform water changes and vacuum the substrate. Yes, it makes it easier to collect the waste but doesn't alter the need for proper tank maintenance.

Yes, I’ll keep that in mind.
Also, feeding fish on 100 percent plant diet reduces ammonia buildup, doesn’t it?

Can it substitute filter using this technique in small tanks where I keep shrimpers and guppy fry?

Since a filter only collects waste in a sponge and degrades it, isn’t this technique similar? Will bacteria buildup in the are behind the glass?

Huh. That sure would be useful in my baby betta's 1 gallon tub. He's small enough that 1 gallon is enough for him, but I can't imagine having 2 of those goldfish in that amount of water.
I siphon out waste with a turkey baster so having all the waste in one spot would be useful.

Welcome

A filter is much more than just clearing waste. Its a home for good bacteria that break down ammonia and nitrates. But water changes are especially important or ammonia builds up to toxic levels.

Its complicated at first, but read about the nitrogen cycle you will understand how a filter is essential in any aquarium of all sizes and for all sorts of fish.

Its a neat waste cleaning tool, but it doesn't substitute a filter. What this would make easier is scooping out debris in between water changes if this was on a larger tank.

So this separator plate is just relocating the solid waste. It is not cleaning or filtering. This is 100% like when my kids would hid their dogs pee spots from me . Plant based data will not reduce ammonia. Waste is still produced regardless of what product is ingested. You must filter the water to remove ammonia, and nitrite and maintain a healthy nitrate level.

Feeding goldfish a plant only diet isn't a good idea, either. They need protein and as varied a diet as possible, as do many omnivorous fish.

Thanks for the constructive replies. But they 75% get bloat if I feed them fish wafers. What else to feed them that won't cause bloating and swim bladder disease?
My goldfish eat API and hikarI fancy goldfish sinking pellets along with broccolI and other cooked veggies, duckweed, hornwort, anacharis, occasional algae wafers and bloodworms and whatever flake food they can scarf that their white cloud mountain minnow tank mates miss that float down.
SwI'm bladder issues can sometimes be caused or contributed to by high nitrates in the water, which build up very quickly with no water changes.
My goldfish are housed in 75 gallon tanks(4 in 1 tank, 5 in the other) and they get the water pretty much completely drained every week to keep nitrates and organic waste levels down. In a one gallon tank with no water changes I would be surprised if you don't have very high nitrates with two fish in there.

processed fish foods usually contain some grains, like wheat. which can cause bloating and sbd. you can use fresh or dried natural fish foods like spirulina, worms, bugs, daphnia, misc aquatic plants, leafy green veggies, peas, etc.

I am currently using the aquatic plant chara.

I see that they no longer eat dead shrimps from my shrimp tank after planting chara.( what can be the reason ?)

It is impossible to get worms and insects as my LFS do not stock them and I live in the middle east.

do they sell freeze dried worms? just soak them in a cup of tank water to rehydrate them first.

My lfs doesn’t carry worms or any of that either so I feed my fish fluval cichlid pellets mixed with herbivore pellets but I don’t know anything about goldfish because I keep cichlids

This betta tank (though too small-don’t get one) works by the same principle. It’s called the “Betta EZ Care.”

It’s funny how they actually didn’t put a betta in the tank for that picture they just photoshopped it on

Best to underfeed Goldfish than to overfeed. I didn't stop having fish contract swim bladder disease till I STOPPED feeding them manually and started using an F-14 automatic feeder. It SLOWLY puts a feeding into the water over the course of an about an hour. The fish can't "gobble up" food like a vacuum - they have swim to find each individual pellet. Makes them more active and they're feeding more naturally. Downside is - they care little for me now when they see me. LOL

I weigh the largest fish - and compute the amount of food that fish needs per day - then I divide that by three and fill that amount into three trays of the auto-feeder and set it to feed three times a day.

EDIT: Also my Dragoneyes do better in 75 degree water than anything below 70. I do not use a heater since my house AC keeps the tank between 70 - 75 degrees.
