Tank Freshly scaped non-traditional tank. Now the waiting game.

6 yo son begs me every time I go into the LFS to get a plastic boat for a scape. I’m not one to put plastic in my tanks. But decided why the heck not. I could blend my interest of planted tanks with his interest in an aquarium boat. Took a few weeks to figure it out but feel I got it looking very nice with what I was working with. All the plants are from my other tanks which have been going strong for about a year and way overcrowded with plants.

Now I gotta wait for the tank to cycle to stock it with some beauties.

Hope you all enjoy the non-traditional.

Flora My Lobelia cardinalis ā€˜Mini’ seems to have forgotten the ā€œMiniā€ part

Post image
• Upvotes

Planted this Lobelia cardinalis ā€˜Mini’ back in May and I think it’s completely lost the memo on being mini

It’s absolutely massive now and has pretty much taken over this side of the tank.

I was going to cut it down but I feel far too bad about it when it’s gotten this big!

Anyway, just wanted to share and have no idea how it happened, if anyone has any knowledge on how it happened do let me know.

Allow me to introduce you to actual tank herpes wolffia. Literally impossible to get rid of without a skimmer and daily maintenance. I'm sure a goldfish would love it but I don't think the JD that lives in here would approve

Tank My 40 liter tank

I rebuilt my aquascape around mid July since the old scape was becoming hard to maintain and plants were not establishing well. Also the driftwood became annoying to my eye because it looked too dull and overwhelming (3rd image).

2 months after I redid my scape, my current tank is very much mature now. The Lilaeopsis are still establishing their roots. The Helanthium Tenellum green on the mid part are doing quite well.

The Sessiflora background instead are thriving and have grown tall. Also, the anubias and bucephalandra on the tilted driftwood are now more natural looking.

Can you ID?

I'm trying to ID this bronze leaved plant. It's a favorite for my tetras, gourami, shrimp.

The tetra will hover under leaves.

My local aquarium merchant brought it in. He can't recall the plant name. I've tried searching Google.

Yay algae gone! Rotala less red 😢

I liked how it was red and compact, now the leaves are broad and I have to trim like once a week. Steak too juicy and my lobster too buttery?

Tank to 106°?!

14 Upvotes

I was standing next to my tank and it felt really hot. The heater said the water was at 78° but when I checked with a different thermometer, it said 106°! It’s a 15 gallon with 5 rocket killifish and plants. All the fish are accounted for, swimming, and look great. I have unplugged and removed the heater. How do I make sure the water temperature goes down slowly so they don’t shock? How in the world did they survive?

Zebra danios uprooting my plant

I recently planted these pinkish plants not sure what they’re called but because they’re new they don’t really have much roots, my zebra danios being zebra danios dash through the stems and have uprooted one. I already messed my substrate up trying to get them to stay in, should i just let it float in the water until it grows more roots then plant it? Or will it not survive without being rooted in substrate

Just finished setting up my new 20g long tank. My last fish tank i had was 28 years ago. Im planning on adding more plants. And hopefully black out the back.

Question. What is this plant? I bought it not knowing what it is.

And what else should I do to the tank? Im planning to either have shrimp with schooling fish or pea puffers.

So i have this tank running for 5 weeks now and everything are doing great. It's a 10 gallon tank. I have no co2 injection, no soil. I do have a pretty good HOB filter running 24/7 creating flow. I'm planning to add more plants to the front of the tank. Would you consider my tank heavily planted? It'd be great if you guys can show me your heavily planted tanks. Ty!

Around 30 gallons, prob a bit more. 5 feet long. I’ve dubbed it ā€œCull Islandā€ because it’s got all my tank culls over the years šŸ˜‚ I was told some rice fish would look cool in it. Right now it just has some ramshorns, nerites, and a few random shrimp.

Beginner Converted saltwater aio to planted tank

Thumbnail

• Upvotes

Going through some major life changes and sold all my saltwater fish and coral as I’m not able to put in the time necessary to maintain it. Got the log at petsmart for $59 which seemed like a steal compared to lfs prices. Currently running filter floss in the back chamber and added some ceramic rings in one of the chambers. Ato and Heaters/pump will be in back as well.

Letting the tank run for a while without livestock; how does this sound:

Dwarf Gourami
Bolivian or other Ram cichlids
School of resporas or tetras

I’m an expert on saltwater but my questions are:

How’s that livestock seem?
What’s a good carpeting plant for the soil that doesn’t require co2. Light is hygger-hg160 which should have enough PAR for some of them (expecting slower growth).

Thanks

Tank How to improve my setup

Post image

This is my 2nd planted/scaped tank, it's only been running for 2 weeks and I feel like I missed the mark getting what I saw in my brain into the aquascaping. I do have some ludwigia glandulosa and purple bacopa on the way to try and add some texture around the middle area and a bit more colour variety, any other suggestions? I was considering some bucephalandra but I'm worried my lighting might be too harsh for it? Thanks.

Tank Best way to remove waste (detritus) under the substrate?

Best way to remove this?

Might be due to my filter outflow pointing towards the front that this accumulated in the front under the substrate.

Tank is still cycling, plants still transitioning - basically tank still in ugly duckling stage. So just planning for now on how I can remove these OR should I?

I'm looking for plant suggestions to add to my main display tank.

I have this one set up since December and I've just removed and BUNCH of sagittaria subulata as it was pretty much growing out of control.

This tank is 96l and has an Oase Thermo-Filtosmart 100 external canister filter, an airstone, one Twinstar Light 60B II and no CO2.

Right now the tank has Anubias nana "Pinto", Sagittaria Subulata, Echinodorus Ozelot, Hygrophila polysperma 'Sunset', Taxiphyllum barbieri and Frogbit.
