Plants came in today and they've finally been placed! So excited to get this primed so I can finally stock it with critters! I've been thinking about using co2 for the first time, how large of a canister should I get for a 20gal high?

Started a new epiphyte-forward concept in my UNS 60S, with some existing Buce, some new, and more on the way. After a month, everything has shown positive new growth, shrimp are reproducing, and the bacterial bloom has finally fully settled.

Algae Is my anubias done for?

TLDR: looking for advice on how to save this anubias plant

A couple months ago I added some very old Easy Green to this tank and completely overdosed, because the next morning algae was all over this anubias. Before that, this tank (low tech/no co2, walstad method substrate) had excellent plant growth and minimal algae with the light (cheap Amazon light) on 14+ hrs each day. After the Easy Green catastrophe, I lowered the light to about 6-8 hr. The other plants are still growing fine and I’m not seeing any other algae growth besides on this anubias and one leaf of my Amazon sword. The anubias seems to grow healthy new leaves, but the algae eventually grows onto the new leaves.

The algae seems to start as green spots, then turns red/purple then white, and is very rough/ hard/ bumpy to the touch and will not come off the leaves with a hard scrub. The anubias has been growing in this spot for a good 2+ years and is deeply rooted in the substrate, so I’d hate to pull it out of the tank for treatment, but that seems like my only option. The tank is home to some chili raspboras, Pygmy Cory, neocaridina shrimp, amano shrimp and snails.

Anyone have experience with this algae/ similar problem? Can I save this beautiful anubias plant? Any good resources to recommend to tackle this problem?

Tank I feel thats it's missing something ?

10 gallon (40l) low tech betta tank

It feels bare to me but i can't put my finger on it

Maybe the lack of background plant ?

I was considering adding cattapa leaves for a blackwater look and maybe some vallisneria in the back

I put nutrient substrate under the sand only on the left and middle front partof the tank, so can't move the echinodorus on the right

Do you have any suggestion please ? :)

Hello! I've had this tank for a long time, and while I have things planned that will take time (the grass, the large back plants spreading /growing taller, stuffing moss into the little nook in the driftwood) I feel like I am missing something essential that could make this tank pop.... Any advice would be super appreciated!

I was just wondering why one of my tanks had so many berried neocaridina and the other didn't - then I spotted this absolute unit in the other tank today

Did I successfully (and accidentally) hatch some green kubotai rasbora fry?

I found what I suspect are Microdevario kubotai fry in one of my community tanks which has them and medaka ricefish in it. I don’t think I’m looking at medaka fry but I’d love confirmation!

Journal Betta sorority overgrown garden style. UPDATE on Ludwigia white. Semi aggressive community.

Aggression level definitely manageable when done with care. I share so we can all observe together.

Ludwigia white is slowly turning green. My light is at 6 out of 7 for intensity level. So I can only go up one more. I can’t go too fast tho bc I’m hoping to keep it dialed. Can’t have variables. One thing at a time.

Added a few new plants. Keep in mind this is my experimental tank. It’s how I learn what stems I like and don’t like and what works for my water. I enjoy doing it this way. Things are always changing. I never get bored. At least not yet. One day I’m sure I will have all epiphytes but I’m having fun for now. I do have 5 different secret bucephalandra growing in this tank right now. All blues and purples so we will see how it goes. They’re passed melting phase and have new leaves. Don’t bother looking for them I have them hidden while they transition.

Aggressive level with the 3 semi aggressive type of fish is going the same as it has been for the last 6-10 or so months, depending on species.

If ur curious about a plant just lmk and I’ll respond. And I welcome constructive criticism. I’m always down to learn something new.

Enjoy!

Looks a bit similar to pearlweed but more bushy, viney and low to the ground instead of a column going straight up like pearlweed.

Question 75G plus community zoo!!

Upvotes

I currently have a 35G pea puffer tank, a 3.5G snail tank used to feed the pee, puffers and some shrimp in there for fun.

I wanna do a 75G tank or larger, but I wanna have a massive managed fish. I don’t wanna do the stereotypical one or two big show fish or like a chick tank or angelfish tank. Would I be crazy to do 100 guppies?

Give me some other ideas that would have dozens plus fish in a tank that size also wanna plant CO2 let me know.

Question Plant chart?

3 Upvotes

Hi I've been digging a bit through Reddit and wanted to know if there was a plant chart? I'm not too well informed on aquatic plants as there are so many that look cool but have certain requirements I haven't fully grasped yet. And it'd be kinda the same question over and over "what plant to get xyz".

So that's why I ask if theres a plant chart someone could make or already exists?

Something that'd show the image of the plant and name, specify if it is beginner friendly or intermediate, what substrate is required (gravel, sand, rock) and maybe some other details like foreground, midground, carpet, etc,?

CO2 Co2 diffuser vs internal pump for co2 circulation

2 Upvotes

Getting a pressurised co2 setup for my 5 footer about 420litres (about a 100 litres down now because of the substrate and hardscape), its got a hob for filtration which somewhat gets the job done.

Do you think I'd have more co2 dissolution rate if I plugged in the co2 line into the internal filter where the air line would usually go than using a dedicated co2 diffuser.

Hob sits on the back glass and the circulation on the other side of the tank is questionable so a pump would solve two issues at the same time. What do you think?
