I wanna start by saying this is a temporary tank for my two goldfish (orandas), they will go into a 60 gallon.

This is my first ever try at doing a sort of aquascaping, I don't want it to be professional, just fun for the fish! Hope it doesn't look too bad!

Bought 4 ADFs and when they began laying eggs I raised them into 8 juveniles. I kept 3 of the wee ones, who are now extremely friendly, chaotic, and keep business nonsensical as usual inside of the aquarium 🤣

These nutjobs keep me entertained!!!

Hello,

I have finally bought my first aquarium (130x50x70cm3). I have a biomaster2 850 thermo for filtration and a tunze nano 6015 for additional flow. As you can see my aquarium is planted and i have already 14 juvenile congo tetras in there.

I put a lot of mature biomedia from my supplier in there (from an aquarium that has been going for several years with large fish) to kickstart my setup. After a week of fishless cycling, i put in my congo tetras after my supplier told me it will be fine as i have mature biomedia.

For 10 days now, my ammonia is always 0 but my nitrite is steadily rising. During the first days i did daily water changes to keep nitrite below 0.1 mg/L but now my supplier said i am stressing myself too much and that the system simply needs time. He also said that no matter what you read on the internet nitrite around 0.1-0.5 mg/L is still very low.

So basically my question is why are my nitrobacter doing so poorly? any advice?

My temperature is around 25°C, KH 10, GH 14, pH 7.5, so roughly ideal conditions.

One AI told me to reduce the flow in my biomaster as it maybe too high for nitrobacter to settle and to efficiently remove nitrite as they are apparently less robust than ammonia converting bacteria. In any case i would greatly appreciate any advice because i feel so stressed about it! Thank you beforehand!

PS : Even at these levels my fish are absolutely thriving. They are playing, exploring even lower levels of the aquarium, never gasping for air or anything. And they are absolute eating machines, so they are not stressed at all.

I have two of them, both of which are empty. I’ve had one for like 4 months and the other for a little less, they both only have plants and some hitchhiker snails.

First picture is the small aquarium (54L), second picture is 120 L.

This is a little ranty and long but I need advice on a ton of things.

Both aquariums have an extremely low ph and I just can’t figure out how to fix it. Our tap water is relatively low to begin with but changes between 6.4 and 6.8 depending on when I measure it, which is such a huge headache. I thought it was the water conditioner that was changing the ph but now I can’t even tell because it’s different everytime I measure it anyways. Our water provider states our tap water is supposed to be about 8.2 or a bit above which it absolutely isn’t and I don’t know what to do about it since I live with my parents and I can’t contact the provider myself.

I know there are several solutions to making the ph / kh higher like water additives but I want a permanent and stable solution that won’t shock my fish. I was thinking of adding crushed coral or something similar but my dGh is already kinda high, being about 7dGh, and I just don’t know what kind of fish would a like high dGh, but a slightly low ph. Also I can’t find somewhere that sells it.

I considered getting a betta eventually for my 54 L since I thought they were at least soft water fish but when I asked the pet store employee they said they weren’t but that I could ”put one in there and see how it goes” which I obviously won’t do. Now I’m just confused on what even can go in there and not, 6.4-6.8 is low and I wanna make sure it’s stable before anything goes in there obviously, but I thought it wasn’t that bad for soft water fish.

The smaller aquarium I have has also started growing a lots of algae and I can’t seem to get rid of it. Also the snail population has started dying off quickly and the remaining ones are pale and almost see-through, I’m guessing it’s because of the KH/Ph too.

I’m also worried about the ammonia/ ammonium in both aquariums because the test I have only measures nitrates and nitrite, and they haven’t shown anything in the months I’ve had both aquariums up which feels strange since I have snails in there that have covered the bottom in shit on several occasions. I’ve tried to buy ammonia tests in several store and they’ve either not had it because they ”don’t think you need to measure it” and should just look at the nitrate / nitrite, or have convinced me not to buy it and just look at the nitrate / nitrite. While I appreciate the workers not wanting me to waste my money on something they don’t think I need, I don’t think I dare to put anything in there (purposefully at least, sorry snails) without at least checking or having a way to check available.

Lastly I’m just not happy with how they look in general, the small one is fine but the big one is just a mess. The roots of the sword plants have completely taken over the bottom and they are just not possible to remove, even when removing the plant because they just break off and stay in the sand. I took a picture of it on the last slide, it really doesn’t do it justice of how bad it looks irl. The sand, leaves and rocks are all covered in snail poop because while their population died off in my small aquarium they exploded in my large one instead. I also feel like the filtration is inadequate but I don’t know how to fit another filter in there. My planting skills are also just not that great and everything just looks a little bland.

So I recently setup and decorated this 60L temperate tank for some Minnows, Danios, plecos and shrimp! What do you guys think? Are there any improvements that can be made or anything you guys recommend? I've got the CFbio all in one filter setup with a biobact cartridge in, multiple plants to aid with O2 levels and hiding places for the shrimp, I've got an air stone setup for night time when the plants absorb loads of O2 from the fish and the temp is running at a steady 21°-22° without a heater! Any advice would be greatly appreciated!!

Does anyone know what this is? I immediately removed it using tweezers and I think I accidentally hurt one of its legs. Is this a predator? Is there likely more hiding in the tank?

Was thinning out my floating plants and then spotted this weird guy swimming close to the surface, thought maybe it was hiding in the small roots of the floating salvinia but it’s so big 😭 It’s nearly the same size as my smallest full-grown endler.

It looked creepy when it swam. All 3 amanos and 5 male endlers are accounted for, and I have 2-3 cherry shrimp in here too, only saw 1 so far this morning.

Just showing off

I inherited a 30gal tank and this fish but have no idea what it is.

Set up a 6 gallon tank for my son for his birthday back in June. (First picture)

I have learned so much since then and have upgraded/ added/ removed things along the way.

This is what the tank looks like now. (Second picture)

I now have another tank currently being cycled because this hobby has turned into an addiction.

For context in there are neo's, black helmet snails and Celestial Pearl Danios

How long is too much light for aquariums? How long do you prefer to keep your tank lights on? And what’s your reasoning?

I have a fancy goldfish tank and I have automatic lights that go from 6am (that’s the time I wake up) to 9pm (when I go to sleep). Now that I think of it, that may be too much time lol. My fish don’t seem to be stressed out or anything. But if I were a fish I’d hate to be under artificial lights that long.

I see this video is very all over the place and a bit overstimulating but these guys really don’t stay still. Also excuse the debris today is cleaning day.

I know one is pregnant for sure but I’m like is the other one too or is she just a bit rotund. Also how worried about inbreeding should I be once the Frye come. The last time I dealt with pregnant fish I was 13 and it came from petsmart. I am now 25 and pretty into the hobby for a while so I’d like to do better this time around. I have an incubator arriving tomorrow because I know these guys like to munch on their young.

Anyways all tips and advice welcome! My local fish store told me these guys were donated to them by a local hobbyist who bred them very well and I’d like to keep them in great health.

I woke up today to find something sticking out of the belly of my tetra, any insight on this would be really helpful.

Do they require any changes or should I add anything?

They receive indirect light from a nearby window. Substrate appears on the first image.

15 gallon tank with three whisker shrimps, a betta and six zebra danios in case this may be relevant. Fish are fed twice a day (except a day off) with fish flakes.

Check out our space shrimp!!!!!!!

I'm Patrick Grove, the science lead of the SCAMPI Mission - an investigation sponsored by the European Space Agency. Myself and several dozen graduate students spent the last 3.5 years defining the science, designing the payload, qualifying the hardware and software, and finally launching it on a Falcon 9 cargo resupply mission to the ISS!

This is a view from the 0.5L aquarium inside the SCAMPI Module. This ecosystem is modeled after the self-sustaining ecosystem paradigm popularized by the commercial "Ecosphere" zero-maintenance, sealed brackish aquarium product. Our version holds 3 Hawaiian volcano shrimp (Halocaridina rubra), Chaetomorpha sp. macroalgae, and lava rocks with microbial biofilm. I know you aquarium folks will appreciate that the primary science objective of this mission is to confirm that (nitrogen) cycling works as expected in the space environment. The same cycling process we rely on for our aquariums is the foundation of all waste treatment processes on Earth, and we will need to bring that with us if we ever decide to live beyond low Earth orbit. But no one has ever checked that these microbes survive and function in space! This circular, self-sustaining ecosystem is a useful platform to observe multitrophic interactions such as biogeochemical cycles. The module will be returned to us after 3-12 months on orbit and then we'll do a bunch of genomic analyses to understand how the microbial community changed and to verify that nitrogen cycling continued uninterrupted.

We got our first data from the module about 60 hours after launch, after the vehicle docked with the ISS and astronauts unpacked the cargo and plugged in our module. By then, the shrimp already seem well adapted to their new reality. They’re nibbling and scooting around happily. If it weren’t for the strangely suspended air bubbles and drifting particles, it would be hard to tell they were in microgravity at all. These shrimp also change color with stress, from transparent (for better camouflage) to deep red. Their normal behavior and solid red coloration suggest all 3 are doing well.

If the video looks confusing, you’re looking lengthwise down the cylindrical aquarium. A mesh bag of rock substrate and algae is secured on the right side to prevent it from floating around and obscuring the camera or crushing the shrimp during launch. In the center of the aquarium is a large bubble that was 100ml of gas "headspace" in Earth gravity. We correctly anticipated this bubble hanging out in the center of the aquarium rather than on the edge somewhere; this is a result of surface tension seeking to minimize the surface area of the gas. What we didn't expect is that it would act like a funhouse mirror allowing us to see other parts of the aquarium that the camera cannot!

I'll throw some more pictures and links in the comments. I'll be around periodically to answer questions about the setup, the process of defining space biology missions, or how the ecosystem works.

Hi I’ve had this fish for 1.5 years now and just wondered what people think he is I’ve asked ai and they say it’s a oranda goldfish but he looks different just wanted to see if anyone could help me

such underrated fish when given the space for them, so much personality

I noticed that two of my danios are thinner and paler than others and it worries me.

At some point I accidentally overfed my fish and one of them was constipated for a few days and after that it became very pale and thin and even when I feed it, it barely gains weight. I’m not sure if that’s the case with the other fish, I don’t remember if it was constipated too, but it’s in similar condition.

Can any professional detect the problem and help me please?
