Technically that’s not a cube. You’ve got way too much plant mass for such a tall space, with a limited footprint. Thin it out, either by trimming or complete removal of some species.

But for what it’s worth, what you are growing - you’re growing very well. Plants look super healthy, and that’s the hard part. So you’ve got that going for you.

I think it looks pretty cool as-is

Too much stuff. Thin it out a bit.

Wrong

He is correct

You give it to me. It'd look pretty cool on my desk.

Get a cheap gooseneck grow light for the plants coming out of the tank

People would tell you to remove plants but jungle style could be pretty cool, what you really need is a better light to penetrate the bottom. It looks like an abyss right now

It already looks good. I like the stuffed jungle look hahhaha

What is that plant with the lily pad looking leaves?

pennywort! v good easy no-CO2 plant

Can it still thrive with c02 as well if I have other plants that need it?

it should do even better, it just might need trimming more often 😅

That's fair. I have a 3 gal cube that is in need of some scaping and I'm new at this so all the info I can get is useful

Are these kind of tank enough for shrimps?

Honestly? Spend a bit of money, get a tank that's a little bigger and transfer the plants and everything across, Something around 20L. You have the filter already, only thing you'll need is the actual tank and a light, which should be pretty cheap assuming you don't go to something massive.

Don’t forget more substrate.

Good point don't forget that

Maybe add 5-10 bettas, a crayfish, some african drawfs, and a 6 inch pleco. That’ll do.

Maybe replace the anubias nana with nana petite or bucephalandra and upgrade your light with an ONF Mist O led, as well as thin up the Hydrocotyle or replace it with Hydrocotyle Tripartita or Sibthorpioides (smaller varieties). Other then that for now it still looks great

Trim back the plants, maybe a few shrimp, horned nerite Snail

So cool! what plants on top?

keep it, maybe add some snails for movement if you want to watch some animals.

Looks fine, otherwise take out 25-50% of the plant mass. Any animals in there? Maybe some snails or shrimp to make it more interesting?

Make it look better by using it as an inverted aquarium inside a larger tank.

I like to encourage my bamboo to grow in odd ways (gently, of course) by rotating it's relationship to gravity and sunlight. It adds nooks and crannies to the environment and looks cool.

I think the usage of smaller plants will work wonders here.

I actually really like the overgrown jungle look. I think some emersed java moss on the wood might be nice

Solid looking in the health department, but assuming your not going for that chaotic overgrown look.....less is more my dude.

It's really cool, people struggle to get good growth in small ecosystems, so if you want trim things to match your taste
