Hello guys,

I'm a rather new to hobby, and got a small 40L planted community tank that has been running really well since I started in February. The tank has no lid, and I don't do any water changes. I just top off the tank every few weeks. Yesterday was one of those days where the water has dropped about 2cm and I topped it off again. Today I came into the room to see my pleco, and a few shrimps lay dead in the aquarium.

Feeding wise, I give my Tetra's some flakes. The rest of the bottem dwellers (the pleco, shrimp and khuli loaches) tend to nom on a piece of cucumber.

I did some water tests (Sera aqua-test) just now with the following results: Ph: 6,5 Kh: 8°dKH NH3/NH4: 0,0mg/L NO2: 0,0mg/L NO3: 0,0mg/L

I'm surprised everything ended up with 0,0mg/L I expected some stuff to be 0,5mg/L is it normal that everything is 0?

Would love to get some feedback from you guys in what could have caused this, i got the best interest at heart for the fish, so please don't hold back on any criticism if things are wrong!

They got really attacked by brown algea in comparison to the other plants.

Haven't grown like at all since a few weeks while they could make a lap on the tanks surface back when i first planted them.

I feel like they only are food for the algea now.

a few days ago i noticed her fins were dark and ripped on the edges, she’s a lot smaller and paler than the others too. i thought she was dead this morning when she was laying on the bottom of the tank but she moved when i got closer. she keeps swimming weird and laying by the filter, and she keeps floating vertically like |

i’ve got 4 cherry barbs in a 34l tank ammonia, nitrite, and nitrate are all 0. ph is 8.8 but i’ve read online not to mess with the ph levels? (the other fish are all ok)

should i do another water change or would that make it worse? i did a 50% water change and cleaned the filter (in aquarium water) yesterday

Hey all! My male guppy this morning is looking and acting a bit off. Last night he was acting like his normal self and then this morning he was hiding behind the heater directly in my HOB's filter current. He eventually came out and this is the video of him.

The two female guppies are acting completely normal. I feed the fish daily with Hikari Nano Pellets and very finely ground flake food for the baby guppies. I did not feed them today yet incase I need to fast them. I unfortunately do not have a hospital tank.

The only thing that has changed in the tank was me adding two Otocinclus last night and a Java Fern. They have adapted fine. The only other thing would be the two slices of cucumber I washed and boiled for the Otos. Any help or advice would be great!

Tank Size: 10 Gallon
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: ~40ppm
PH: 7.4

Stock:
Four Neocaridina Shrimp
Seven Habrosus Corydoras
Three Guppies (plus babies)
Two Otocinclus
One Assassin Snail

Hey all, I currently have a mild tempered male shortfin koi betta that I will be upgrading to a ten gallon. I want to add some additional biodiversity but don’t want to overdo it. I’m thinking the betta + a school of Pygmy corydoras + a couple snails. Thoughts? Is this too much or can I afford to add anything else? Additionally I plan for the tank to be heavily planted both for aesthetics and biological purposes.

My friend is looking into getting a 2500l (660 gallon) pond.

Where he lives he can get cold winters and is looking for a way to keep it above preferably 17°C (62.2°F)

Anyone know how to achieve this?

Thanks.

Black water tank with a bit of Mopani wood. Rest is plastic. Also on the glass.

My limestones would typically be used as a base for bonsai landscapes. Step one is not to clean it, but to get moss to start growing on it. If, however, this is interesting to an aquarist, I'll clean it up all white and sterile. But what would be a good price to an aquarist?

It is 25" x 14" x 4" (LWD) and weighs 39lbs.

I just noticed my blue diamond shrimp is carrying eggs, do I need to do anything special for the babies?

This is my first time keeping shrimp, and I just noticed one is full of eggs! It’s a community tank with 7 panda corydoras and 10 glo zebra danios. I currently feed shrimp pellets from a local store and they also skim around for leftover fish food and algae/biofilm. Do I need to change anything or feed something special for the babies? Do you think any might survive in this setup?

Parameters: Temp: 76 degrees Fahrenheit pH: 7.4-7.5 KH: 3 degrees GH: 4 degrees (I order seachem equilibrium to raise this slightly, sometimes it reads 3 degrees) Ammonia: 0ppm Nitrite: 0ppm Nitrate: 5ppm

I’m wanting to get this tank and stand for my wife for Christmas. I have, a what I would call an irrational fear, of the stand collapsing and water going all over. Are these stands sturdy or are they simple particle board that will raise concern about being wobbly and such down the road. That’s a lot of weight above that stand. Is this a good idea or not to get this combo from petsmart?

Hi everyone! I added these water lettuce in a few days ago and I noticed this morning that they had this white fuzz growing on them and seem to be melting I think. Wandering what that white fuzz is and what I should do. Any help appreciated!

A few more details. Newly cycled tank Plants were moved from outside mini pond into new aquarium. Hygger 957 light that was shining directly on them but I just put a glass hood over aquarium this morning. Water parameters are great. I've checked everyday since adding fish 6 days ago. I have started to get very tiny little hair algea in tank. I do have a fluval surface spray bar that was moving plants around for a couple of days but I put a temporary ring to help keep them in place and not getting dunked underwater.

Really hard to get a decent picture but the are white/see through and look something in between a snail and a shrimp??

I’m planning on using this as a shrimp tank in the future so just wanna know if I need to be worried about them 😊

All parameters in my 75 gallon are perfect except I have a large ammonia spike. I’m hanging around 2 ppm.

I lost two fish in a matter of a few days.

I’ve done a water change and cleaned my canister filter. 30% change and my ammonia is still hanging at 2 ppm

I have a natural dirt bottom caped in sand. heavily planted tank.

I’ve ordered API ammonia lock and it will be here tomorrow.

I rescued 3 Kuhli Loaches off of Facebook marketplace a few months ago and I’ve been setting up a 20gal long for them to upgrade to. I’m going for a semi-naturalistic look: sand, leaf litter, a little bit of tannins, and it’s of plants.

I’m absolutely getting more Kuhli loaches as that’s the main focus on the tank, but I’m excited to plan for other community fish to go in as well!

What I’ve been thinking so far:

• Kuhli loaches (8-10)
• Celestial Pearl Danios (8-10)
• Chili Rasboras (8-10)
• 1 honey Gourami (or maybe Betta Hendra)

Would this stocking be too much or would it be ok? First time doing a community tank

I have that as a tentative idea of fish to choose from, but I would love other fish recomondations that are cool/unique and would go well in a 20gal long community tank! Focusing on fish that are from around SE Asia/Asia area.

My filter is a top fin cartridge with carbon in it so I took it out and put it in a bucket with tank water. I then put a non carbon filter back in. Will my carbon filter be ok in the bucket of water for a few days? Should I do water changes daily on the bucket as well? Just don’t wanna loose all my good bacteria. Also I dosed my first dose last night and it turned the water fully blue but when I checked on it in the morning all the blue was gone. Is that normal?

Anyone know what kind of Algae this is and how to treat it? Currently the only plant with this on it.
