upgrading established tank

i have a 1g tank on my desk at work in which i have achieved microfauna so i'm super chuffed with myself.

now i wanna upgrade them to a 3g tank. i have a bottle of water aging under my desk so the age of the water shouldn't be a problem.

also, i'm gonna cannibalize literally everything from the old tank, water, plants, filter media, even substrate

am i correct in saying i could just add all to the new tank and all should be fine?

Filter recommendations ?

I have a 8 gal corner tank win the shape of a slice of pie… the filter that’s in it is rather big & clearly I could have used it for a larger tank (I got it for free so I just used it)

But because it takes up sm space, I was wondering if anyone has any recommendations for small filters that are reasonably quiet and suitable for my 8gal?

How to get guppies to realize there’s food

I’ve been feeding them at the top of the tank but now I’ve gotten this device so how can I get my guppies to realize that there’s food in this new bowl?

cherry shrimp pairings

looking to finally reintroduce cherry shrimps to my tank after i lost the centerpiece dwarf cichlid.

now, im just aprehensive if its safe to put them in with my kali tawa dwarf rainbows that are only a few months old although im more concerned with the morpho tetras as i know theyre more of the predatory types.

btw, how do i post videos off my phone? it only gives me photo options even if i use the Video Tag.

Purigen question

Is there any way to use Purigen in a nano tank that only has a sponge filter?

Tiny Jungle (1G)

I was planning to keep it more "trimmed", but I'm liking the wild look more and more.

Will probably add some of my cull shrimplets when they mature.

45gal nano tank centrepiece ideas?

Hiya!

I have a heavily planted low tech 45gal i've set up as a nano tank, with emerald dwarfs, embers, (and some sneaky burmese glowlight danios), I also have some other nanos like beckfords in other tanks that I can shift around.

i'm trying to think of a nice centrepiece fish that will complement them well, and maybe leaning more towards the colder end of the colour spectrum -blue, green, purple, etc. (i'm thinking of adding some super-tiny-nanos too, but this will be later and dependant on the centrepiece fish)!

so far i've considered some gouramis -i've kept sparkling/croaking/honey's before, and i'm not too sure if i'm sold on dwarfs yet!

i've also considered gulf coast pygmy sunfish but i'm not sure if they're available in my country/am still researching c:

any suggestions welcome!

Ideas for a 1 gallon no tech tank

I've had this gumball machine for years with the intention of turning it into a nano tank and finally got around to converting it to a tank.

This will be all plants for now with the intention of adding a snail and potentially a few shrimp later on.

I'm looking for ideas for plant stocking. I realize I'm extremely limited as it will not have a light, filter, or air stone. It will however receive natural light from the nearby door. I can also move it if it becomes too much or not enough.

I already have a couple anubias Nana's petite I can transfer into it and I know they barely need any light to survive. I have some crypts I can transfer too, but I'm not sure how they'll do in such low light.

Any other suggestions?

I already have some fluorite on hand, so I decided to use that as substrate. I figure it will also make it a bit easier to plant in since it's heavier versus any type of soil.

Downsizing Tank Advice

Hi y’all!

I currently have a 5 gal freshwater tank with 2 neocardina shrimp (I had more but they’ve died) and an assassin snail. My partner is taking over the shrimp and adding them to his tank.

The snail was a stowaway in a bag of plants that I got too attached to. I’m unwilling to part with the fella but I don’t want to keep a five gallon just for him if I don’t have to.

With just the assassin snail, how small of a tank could I downsize to? I’ve never done a nano tank and I had trouble searching for info online about the minimum tank requirements for a single snail.

What are those critters?

Hello everyone. Two weeks ago I started brand new 25 l tank. I placed driftwood, planted elodea, bacopa and cryptocoryne. I don't have any shrimps yet. I was just about to do small water change and overall maintenance and I noticed very tiny critters crawling on the glass. What are those? Are they harmless? I can also add video of them moving but like I said they are very very tiny I had to use macro lens to capture them. In my previous tank I had critters that were hopping on the surface and I read they're harmless but I never noticed anything like those tiny worms.

Bad Aquascaping

I literally do so much research and planning and my shit still looks like this 😭 I moved my cycled 5 gallon stuff to the 10 gallon. Do I need a long siphon?

My planted tank

I built a little ~3gal tank from a counterside knickknack, gave it a layer of substrate and planted a variety of pet store things to match.

It's been stable on the water quality side for quite a while. Got a range of cherry shrimp in there as well as a couple of neon tetras. Probably overstocked on paper, but the plants keep it well under control.

That said, I will need to figure out how to trim back the root growth from the monstera on top. Ideally before it roots itself in the substrate. The shrimp love hiding in the root ball but it's starting to look crowded in there.

Any thoughts?

2.5 gallon scud tank

I discovered some scuds on some plants I purchased, and I didn’t want to add them to my 40 gallon, and I didn’t want to kill them. So I put them in a temporary holding jar, and I set this lil tank up for them last night. It’s kinda gonna be just a lil experimental tank, but I’m excited to see what happens.

Stocking a 40 gal?

Hello! I have a 40 gal breeder that I’m (hopefully) going to start prepping soon. I want it to be a nano fish community tank, and was hoping to get some help with what to stock and how much. I’m making a spreadsheet for everything + care and costs, so I want to get everything together asap. This way I can have a checklist that’ll help me keep track of everything.

I will note I am fairly new to this hobby (I have had 2 bettas), so if anyone has advice or an idea that would better suite my skill level that would be appreciated. I originally had this tank for an axolotl but was uncomfortable getting one without more experience and I love the idea of hardscaping my own tank and having it all be nano fish.

The tank will use a sponge filter and a bubbler. It will have two caves, one for shrimp (figuring out how to do that) and one for fish. One side will be more densely planted than the other, with fluval stratum and sand. There will be some driftwood in there, but it won’t provide much hiding spots. I have some flat rocks I can use to make hiding spots. My hope is that some of the species will breed so I don’t have to worry about buying a whole ton of fish, but I’ll suck it up if that won’t work for this setup.

Sorry if that was a lot of information, I wanted to make sure everything was there in case it was relevant.

These are the species I know I want:

  • Cherry shrimp
  • Oto catfish
  • Kuhli loach
  • Some kind of guppy

Here is the list of other possibilities I’ve come up with:

  • Rummy-nose tetra
  • Honey gourami (iffy)
  • Peacock gudgeon
  • Cherry barbs
  • Green neon tetra
  • Congo tetra
  • some kind of rice fish
