Aquariums and Fish Keeping

Does anyone have experience with seiryu stone in their aquarium? I'm planning a dieted tank and was thinking about getting some, but I keep reading conflicting information about it with regards to raising the PH. Either it barely raises PH at all or it'll kill your entire tank. What has been your experience?

Hi, I'm pretty sure my corydora has cotton wool disease on its top fin and I'm not really sure what to do. We've had him quarantined for nearly two weeks and are daily treating with PimaFix but it doesn't seem to be helping at all, rather it's growing worse.

The good news is that he seems completely oblivious to it all... he still swims around like normal and scrounges around for food.

Is there anything else I can do?

Edit: I've tested the water and all parameters seem to be fine. No nitrite, nitrate or ammonia and the pH seems average

Once I bought a set of plants cheaply, but the disadvantage was that even the seller himself did not know the exact names of these plants. Please help me roughly identify the plants in my aquarium if you have free time. :)

I know that there is a bit of Java moss in the upper center.

Thanks all for your answers.
2.- I think it is Ludwigia Repens. And it's across all of aquarium.

Recently planted this aquarium with stems and mosses. This long thin green moss-like plant showed up and I like the look of it. Hoping ot is something I can cultivate and use for a hanging vine effect on my driftwood and not a pest plant. Any help is appreciated.

I tried to get most of my 10gal aquarium setup secondhand, but I got a new LED hood with a day/night light feature. I have since caved to peer pressure and put a couple live plants in there, but while my Anubias Glabra has been putting out a new leaf on occasion, the older leaves have been getting black spots.

I'm not sure if the "night" light is just a blue light, or if it's a blacklight and I've been torching my bebe plant with excess UV beams for 12-14 hours a day.

It suddenly appeared and took over most of the aquarium floor and wrapped around some plants too. It looks terrible and no matter how much I change the water and vacuum the aquarium, it comes back after a couple of days.

Can I cultivate live food in the same tank as my Endler guppy? (I plan on adding other fish in the future). I have read that it is not smart to grow daphnia as they reproduce very quickly and outcompete for oxygen.

So is it possible to breed live food in the same tank to create some kind of biome, maybe with some other species? (Monia, fairy shrimp, Rotifer Brachionus)

How does the nitrogen cycle “survive” large or even 100% water changes? I don’t want to stir up a discussion about what is best, and I understand that we all live in different places were conditions and water quality is different and also that we all choose to keep our fish differently because we thinks its the best for them. Therefore I am simply looking for an explanation on how the idea of regular huge water changes works in practice.

I see recommendations of very large water changes in goldfishkeeping, especially in bare button setups and grooming setups. This is very practical, for systems that are heavily stocked. I also see them have filters in them, and this I can’t really understand, unless they are there only for mechanical filtration.

What stirred up this thought, came from a recent experience where I lost some fish. I had a tub with 10 fry in a tub (90 lit – 20 gal) with fresh tap water (no chlorine or chloramine in our systems here). I added a cycled filter from my main tank. I then added the fry (after acclimatizing them slowly) and I expected this to work well. The fish got a very serious fungal infection within 3-4 days, and I lost most of them.

My theory of what went wrong is, that the cycled filter did not have access to ammonia and nitrite to maintain the bacteria balance, and therefore crashed. The breeder that I got them from, told me that he changes the water daily, but he had approximately 100 fry in a tub that was the same size, so I assumed that a cycled filter would have not issue with keeping up. I fed them 3-4 times a day but very moderate quantities so I did not expect the system to crash like this

So my question is, do very large water changes work, if they are not made often? Don’t larger water changes crash or almost crash the filter in systems that reliant on biological filters? In systems that are reliant on biological filtration, is partial water change not better, to maintain a more balanced filtration performance?

I've been fighting it for awhile. Various nutrient levels, light levels, etc. Considering getting a nerite snail, but heard they can be a bit of an escape artist. Any tips?

I recently upgraded my phone, and I'm having a better time with tank photography. Here is the least potato pic I've taken of my boi Diogenes.

He's recently turned very blue. He deffo was not this blue even last week. He was, tbh, kinda shit-colored with blue tints in his fins when I first got him.

He's also the most puppy-like out of the couple-few bettas I've had. Corbulo was leery of fingers and faces near his tank, but Dio just wants to see what's up. I wonder if it has anything to do with breeding -- are wild types or wild hybrids less grumpy than most bettas?

They're (impossible to tell gender until they quite literally start breeding) pushing past 2 inches! The patterns are coming in on the dorsal and tail especially right now! They will keep growing up to ~10 or so inches, so a long road ahead! They'll be the tank boss when they're bigger but for now that's left to the Angelfish and Electric Blue Acara :)

If you're curious what an adult looks like, check out this great video by PrimeTime Aquatics (channel definitely recommended)

My poor dude Corbulo kicked the bucket a few weeks ago when I fucked up planting his tank. I've been waiting to see if I killed the plants, but at least one (1) is growing.

I already had 'Diogenes' picked out as a name for my next betta, and it seems like a name for a something in the yellow-red spectrum. Except I also liked the look of the 'alien' boys, which mostly come in blue.

So I picked a rather bland speckled boy who may or may not be a wild type. I hope he brightens up as he grows.

My crypt undulata has had 3 weeks to melt and be dramatic, but I can't really tell if it's doing anything under the fuzz. How long before I can say that I gave it a good run before I yoink it for something else?

My anubias, planted at the same time, gave me a new leaf so I'm not totally hopeless.

About 10 days ago I noticed a baby fry (believe its a guppy) and now there's 3 more! Funny thing is that I took this picture earlier this morning and now there's another one! So I now have 5 baby guppies!!!

Got back in to this hobby about a year ago. Currently only have a 20 gallon tank, which houses 12 fishes, making it a community tank.

Things have been great but have to admit I have lost some due to not knowing what I was doing.

Fast forward and things have calmed down, without any others dying. Nitrate has been a constant battle which has led me to weekly water changes (50%). Also as of late but cutting how much I feed them in basically in half.

What it seems to be happening is that one of my Goldfish who is currently all white (used to be gray) is now turning orange. Is this normal?

I picked up one of these fluval 13.5 gallon aquariums, and it has a little chamber for filtration on the back. SOMEONE ripped up the default foam block that fits in there, and it got me wondering if I could use some of that modular foam that comes in pelican cases? Or should I just buy the replacement?

This fish has been getting worse over a longer period of time. It does not seem to be related to swim bladder issues, but more neurological. I suspect that it has gotten an aneurysm or brain damage some how.
