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

Looking for heat/filter suggestions for planted UNS 3N (shrimp only).

Have my hardscape near finished (just a big pieces of seriyu, and will be lowering the substrate level before going live), and will be planting Monte Carlo throughout, and reineckii mini and likely some fast growers to kick start things.

I have a Oase Filtrosmart Thermo 100 on my 45U (9.5gal), but assume getting another one for the 3N would be overkill.

That said, I really like the idea of an integrated heater, and the Biostyle Thermo 30 is far too big for the tank.

Open to suggestions. Will be a high tech setup with CO2.

Small inverts

Hi all,

I have a 3-gallon jar on my desk at work with a single Dario tigris in it. As such, I feed with Grindal worms a couple of times a week that I store in a small takeout container in a drawer at the same desk.

Owing to their ambivalent behaviour toward food of any kind—a peculiarity I don't think I've encountered in any other fish—I tend to overfeed a bit to ensure the little dude actually ingests something. He looks extremely happy and healthy and is otherwise a delightful little fish.

Anyway, I'm looking for an invert (or fish, I guess, but I'm trying to be mindful of the bioload) larger than a scud but smaller than a Neocaridina. My hope is that he or she wanders around the substrate and picks up anything the Dario might ignore.

There is a culture of scuds going in the jar but it is quite small now, thankfully, as they were tearing up my plants. Manual removal of adults and letting the Dario eat the smaller ones worked out. I might see a single one in an average week if I'm (un)lucky, now, and if I do see one, it's juvenile. There are also a few species of so-called "pest" snails doing their thing. Conspicuous but under control.

I'm digressing.

I'm not picky with what the new guy looks like, just want the function of a sweeper. Not a scavenger—these are live Grindal worms—but something that actively hunts for small critters. Did consider selecting an especially small adult pygmy Cory from my colony as an occasional mercenary but hoping to avoid that.

I'm hoping that with the way aquariums are trending—smaller—there will be more options in the future as there are literally millions of aquatic invertebrates out there. I'm sure only a very small percentage are viable for aquariums for various reasons (lifespan I suspect being the primary one), but I'm certain that we'll have all kinds of nano critters available in a decade.

But until then, any ideas?

What do you think?

I started with cycled soil, and cycled water from another project, immediately went into a massive algae bloom. Only plant that really melted was the Anubias in the back right. (Of course I left the rhizome) scrubbed the rocks a few times, and boom, week 2 no algae. After this I slowly started adding my prized single stripe BCR shrimp, last week added the final fish. Boom. With proper practice, careful attention, and good knowledge of water parameters and anything is possible.

Been running for 6 weeks. Filterless. Pumpless.

Daily 5-10% water changes with Reverse osmosis.

Daily siphoning of detritus.

Feeding is brine shrimp or daphnia depending on what I’m feeding my other tanks.

20+ black crystal culls from my breeding project.

4 chili rasboras.

2 Glass rasboras.

I told my homie at the LFS, expecting him to behead me on the spot. MFW, he informs me he’s been running a filterless salt set up for years.

Do I add an air pump?

Currently my tank has shrimp, snails and three fish, two clown killi and one rasbora (currently cycling a 9 gallon to accommodate a shoal) If seen mixed info on air pumps - I have one to put in but I want to make sure I’d the right choice!

What do you think?

Hello everyone. I want to utilize this rack. Each shelf is rated 113 kg about 249 pounds. I just got small tank (25x25x40) 25l - that's about 6.6 us gallons. It sits almost perfectly over those two furthest support wires. So my question is should I place the tank on top of some plywood and foam? Maybe the foam will do? What do you think?

High tech algae ID

I dont think this is BBA, but not sure - can anyone help ID? Is it diatoms?

I have a 5G high tech tank with pygmy cories. This broke out pretty bad when I was away for a month, partly from less water changes and also inconsistent CO2. I have seachem purigen in the filter.

Nitrates are 5-10ppm, phosphates are low at < 0.25 ppm (probably bc the algae is using them... sigh). No ammonia, nitrites. I dose with NILCOG thrive plus 2-3x a week, water change every 1-2 weeks.

Substrate is controlsoil, but there is a little sand in there too.

Low tech carpeting plant suggestions?

Planning on setting up a 20cm cube tank for my desk. The tank will probably be low tech. Just an HOB + full spectrum light, and no CO2. Anybody here had success with either Cryptocoryne Parva or Marsilea Hirsuta on a similar setup? Or better to go with Dwarf Hair Grass?
