r/Aquariums

I just rearranged my bedroom furniture and realized this may not be a safe idea. Getting ready to go to bed so wish me luck!

Love watching these guys show off!

Some sort of arachnid?? I’m unsure.

Are these ok reading for my freshwater setup? This is the first aquarium I've had in a while.

I have 5 Amanos and bladder snails as my livestock for now. I'm only planning on adding either a honey gourami or 3 to 4 Endlers (all males) in a couple of weeks.

I will admit that I jumped the gun on adding the Amanos too soon, but they've seemed to settle in now. They graze all over the tank and don't seem interested in the ghost feeding I've been doing for the tank.

I finally got a DiY CO2 injection system working this morning. It took a couple of days to troubleshoot my setup.

I have live plants in my tank; Long hair grass, Anubias, Java Fern, Java Moss, Kings Crown Java, Banana Lily, Anacharis, Salvinia Minima, Red Root floaters, and maybe some Dwarf Water Lettuce (if any of the peices I got regenerate)

Current Parameters and Kit:

10 gallon tank

GH : 180 ppm (according to API Testing strip)

KH : 120 ppm (API Test Strip)

Ammonia : 0 to .25 ppm (API Master Kit)

Nitrite : 0 ppm (API Master Kit)

Nitrate : 10 to 20 ppm (API Master Kit)

pH : 6.4

Heater : busted (may not get a new one)

Temperature : 69.1°F

Lighting System : Hygger HG999 (programmed a 10-hour lighting cycle at 70٪ brightness with a 4 hour moonlight cycle)

Filtration : Modified HOB Filter with live culture media and a sponge over the intake.

Fertilizer: Aquarium Co-Op Easy Green (i dose once a week the recommended 1 ml per 10 gallons)

This is my 2-year-old low-cost, no-CO₂ planted mini tank.

I’ve mostly tried to keep things simple and let the plants grow naturally without investing in a high-tech setup.

Setup:

• 🌱 No CO₂
• 💡 Basic/low-cost lighting
• 🪨 Natural stones and gravel
• 🌿 Mostly easy, low-tech plants
• ⏳ Tank age: ~2 years
• 💰 Built on a fairly low budget

I know the tank isn't perfectly aquascaped, and some of the older growth has become a little wild. 😅 But I actually like the mature, natural look.

I'd really appreciate some honest feedback from experienced planted-tank keepers.

1. How does the tank look overall?
2. What would you change or improve?
3. Should I trim/replant some of the overgrown plants?
4. Would you change the hardscape or keep it as it is?
5. Are there any low-tech plants you would recommend adding?

I'm especially interested in improvements that don't require CO₂ or an expensive setup.

Any criticism or suggestions are welcome! 🙏🌱

Thanks!

In the past 2.5 months I’ve lost 2 pearl gouramis, 2 male kribensis, 4 red banded loaches and 1 beta in my small neocardina tank which had some scale damage (that’s why I moved her- so she could heal. I thought maybe there was some drama. The scales got better mostly but then got bad again and she just died from one day to the next. No pineconing or anything)

1 gourami did look skinnier before dying but was eating and pooping.
1 kribensis looked lethargic the day before dying but was eating normally.
The rest seemed normal until disappearing including all the loaches which ate so much and were fat and active as hell.

All my tetras and amanos are absolutely fine. My raspboras and neocardina populations are thriving. What the hell is going on? Why are these fish dying randomly?? Is it parasites or something? But if so why is it not more obvious? Why no wasting? Why are their colours vibrant? Why is everyone acting totally calm and normal??? I’m sooooo confused.

Hello! I have this 11ishg long/shallow tank (picture in comments.) Its about 35inches long and sits on the back of my (reinforced) desk.) It is done cycling, just working on raising the KH (and ph) a bit to stabilize. I'm not in a rush. I have another tank thank that is neo shrimp and green neon tetra. For this tank, I'd like something a littttttle more centerpiece-y and/or social? I know if I have shrimp, it limits my options because they will get chomped (I'm ok with some murder, but not enough to discontinue the colony.) But I will be staring at this tank literally all day while I work.

I have a fluval 107 with pre-sponge and optional air bubbler/magic fortune ball in the middle.

What would you choose/at what size schools? My ideal would be shrimp, some shoaling/tiny guys, and a small group of something a lil bigger, but that may be asking a lot. I'm choosing between chili raspbora, pygmy cory, otos, celestial pearl danios, blue dwarf goby? Killifish? Should I skip the shrimp to get more interesting fish?

ETA: I know the water is low rn! It will be filled appropriately.

200 × 60 × 90 cm . it should be for a 200 cm x 60 cm x 50 cm height fish tank ( 600 liters , likely 700 kg total mass ) . does this look adequate ?

In imperial units this 79" L × 24" W × 20" H , 160 US Gallons .

Edit : this is the work of a local Guy that charges a hefty premium for custom made fish tanks , i am curiously what you people think about that one .

Hello,

I have a 20 gallon aquarium (pictured) that presently only has 2 platies and 2 other livebearers (I am unsure what these actually are, they were sold as 'banana platys' but appear much smaller than my other two platies, and are apparently also sold online as 'mini mollies'.

I had purchased 3 female platies on Friday, all 'sunset' variants. From the outset they seemed to be a little lethargic, though this may just be compared to the smaller livebearers which are very active. However during feeding they were active. I did a 30% wc as I do on Sundays.

I'm not sure when it began, but the platies have been looking increasingly lethargic day by day, usually preferring to hide in a corner (sometimes at the bottom, sometimes at the top), or sometimes between the rocks. However they still came out eagerly to feed each day, until today, whereupon they were totally indifferent to food.

Their daily staple is aqua one spiralina flakes, though on Saturday I fed them instant brine shrimp, and on Sunday blanched peas (blanched for 10 minutes and then with the shell removed). I fast them on Monday

One of the 3 platies died this morning (Wednesday morning), unfortunately I did not take a photo of it but I realise I should have. Later when I fed them today they were not interested in the food, though my other 2 livebearers were. I did leave after 3 minutes though, maybe they came back to eat a little later, but I'm not sure.

• My water parameters: ph 7.8
• gh 8-9
• kh 3
• tds around 300
• ammonia 0
• nitrites 0
• nitrates 20
• temperature 22.8c (73f), heater set to 21c (70f) but temp is usually 22.5-24 (72.5-75.2)

Tank information

• Inert (sand) substrate
• 20 gallons
• Other livestock: 40x neocaridina shrimp and a similar amount of ramshorns, taken from an older tank, all seem to be fine
• Plants: jungle val, blue stricta, rotala rotundifolia, ludwigia (unknown variant), small amazon sword, pearlweed
• Plant sources are diverse: some from an old tank of mine, some from a friend with an even older tank, some recently purchased
• 10 hour photoperiod
• aqua one internal filter and heater both rated for a tank this size

At the store it was said to be "Blue Apistogramma", and searching on Google, the only species to be called that is Apistogramma trifasciata. But i'm still not sure.

A few of these blobs have turned up. I have a bunch of shrimp, a handful of neon tetras and guppies, and a few mystery snails. Any ideas of what these could be?

I’ve had my 60L tank for about 8 months now and i’ve come to the conclusion that I’m not a fan of the plant arrangement.

Any advice on how to rearrange the plants, etc? I also have some Amazon Swords and Cryptocoryne to add.

This little guy accidentally made it into our bag of cardinal tetras. What species is he? He won’t school with the cardinals and I’d like to get him some friends. :-). Google Lens is giving a lot of different suggestions.

Recently they started acting like this. They will swim in the open water all day, and night as well. Silver vetsions are still shy, but these got even more active as I add more of them. Now just 6 kuhlis in the 150gal tank.

Are they stressed?

Are they feeling secure and happily enjoying the tank?

My molly and guppy keep die with very high rate, today i decided to use my microscope to check, and i found these worm on the skin of the fish. it seems like some type of parasite.

i am doing 30% water change every 2 weeks, but still the death toll is still very high, and it is now infecting my second tank.

appreciate if any guru can give me a suggestion. this is a 240l tank with lot of plant. should i totally abandon it and start over? i have about 50 fishes now.

Just like the title says, it's been a rough stretch.

I'm a big rainbowfish fanatic and have been keeping a mostly rainbowfish species tank the last 5 years. I would also call myself a fairly experienced and seasoned fish keeper. But I'm human and I have hubris and the latter has really humbled me in a pretty intense and devastating way recently.

Recently, I purchased a pair of glossolepis wanamensis (emerald rainbows), one of my favourites that I previously kept. Normally when my wife and I go out to an aquarium shop, we don't stay out for much longer and go home within an hour or at most, 2. All my past experiences before have never given me trouble. The staff member at the store bagging the fish even asked how long we were gonna be before we arrive home, and I said, it's not too far, probably an hour or so.

My wife and I were enjoying our time out, but every hour that passed, (who by the way only fairly recently got into aquariums largely because of my love for aquariums) she urged me to go back home for the fish, to which I responded, "It'll be fine, we won't be out for long.". I kept saying this until we got home 4 hours later.

Before I continue, I should also say that throughout my fish keeping tenure, I never quarantine new fish I buy and they pretty much go straight into the main tank after acclimating. I almost never ran into issues with that, but yes, I do know the folly in that logic and it's a very poor habit to have as someone who is experienced at fishkeeping.

That said, after acclimation of the wanamensis pair, I released them into my main tank. The following days, up till today has been a complete nightmare as a columnaris outbreak wreaked havoc in my tank. Everyday, a rainbowfish or two would end up in the bottom of my tank and then I would notice one or 2 more with the classic symptoms, locked jaw, fuzzy mouth, cotton like patches, saddleback, visible slime coat issues, extreme lethargy and they go on to die the following day.

I've dealt with columnaris before, but never at the rate it devastated my tank. The wanamensis pair due to being in the bag with little oxygen and no medication for hours were in so much duress in the bag, severely compromised their immune system and ability to fight off the bacteria. The female died the next day and I should've seen the signs on the male right away (white tail, fin rot) and should've separated it and started treatment immediately.

I have started medicating the tank by making medicated food using the flakes I feed them along with Knox unflavored gelatin and kanamycin. It seems to be helping and 1 of the previously really sick ones seem to be showing signs of recovery. All other fish that showed severe symptoms have been separated into a hospital tank. Unfortunately there were too many that were too far gone, that I couldn't save them.

I lost several rainbows, most being 3-4 years old that I've had since they were juveniles, including all of my large mature boesemani males. It's been heartbreaking and soul shattering as I love my rainbowfish. I know this is on me and I feel so defeated and stupid. I should have known better. All I can do is learn from this tragedy as best as I can, move on and be grateful for the fish that I still have and give them the best care I can.

I just wanted to pour my heart out a bit here, because if anyone can relate to my pain, I know it's you guys here in the aquarium subreddit. Thank you for sharing your time. And I'm sure most of you will be wiser than I was, but it's worth saying anyway, please don't make the same mistakes I made and please don't develop the bad fish keeping habits that I did. I will definitely be quarantining any new fish from now on for a substantial amount of time.

To all my big beautiful boesemani boys, my sentani girl, my 2 bedotias, and my trifasciata boy and the 2 wanamensis I barely got to know...I'm so sorry I failed all of you. I miss all of you so much.

I attached a few of my recent favourite photos of the fish that I lost to remember my gorgeous fish. I hope you guys can appreciate them as much as I did.

Thank you, peace and love.
