New pin badge design!

The CPD is one of my favourite nano fish so I had to make a pin badge design of them! Which fish would you like to see next? I’m planning on doing a few of them!

What fish are the most interesting to watch that also work with shrimp?

It seems like most of the usual suspects (Betta, gourami, scarlet badis, dwarf puffer, etc) would love nothing more than to eat all the shrimp.

Are there fish with interesting behaviors that also work with shrimp?

Thanks!

16 gallon bookshelf help!

Hey! I've been planning on getting a 16 gallon bookshelf Aquarium (link) and was wondering which one of these ideas would work best!

Measurements - 33.85L x 9.84W x 11.02H inches

I used AqAdvisor but heard mixed opinions on the accuracy of it.

(1) Cockatoo Dwarf Cichlid - (6 to 8) Chili Rasboras - (6) Dwarf pencilfish - and a few Netrite snails

(1) Cockatoo Dwarf Cichlid - (6) Chili Rasboras - (6) Rummynose Tetras - and a few Netrite snails

(1) Sparkling Gourami - (8) Male Endlers - (6) Chilis - and some cherry shrimp

(1) Betta Imbellis - (8-10) Rummynose Tetras - some snails

(1) German Blue Ram - (6) Rummynose Tetras - (6) Chili Rasboras - some kind of cleanup crew

Im open to any ideas or pairings of these fish
Cockatoo Cichlid
Dwarf Pencilfish
Chili Rasbora
Phoenix Rasbora
Sparkling Gouramiarers
Spotted blue-eye
Betta
German Blue Ram
Rumynose Tetras

Although my favorites are - Rummynose tetras - Chili Rasboras - and Cockatoo Cichlids

16 gallon help! First tank!

Hey! As my post says this is going to be my first tank (I had a few family tanks as a child but this will be the first one I own myself)

I am planning on getting a 16 gallon tank (Aquarium) and I was wondering about some stalking options

Its going to be pretty heavily planted and have these items in it
Light - Aquarium light
Heater - Heater
Filter - Filter
Lid - Aquarium Lid

I have a lot of fish I like but have decided on these, I know I cant keep all of them together in such a small tank, I'm aiming for 2-3 types of fish and shrimp or snails. These are my options

Cockatoo Cichlid
Dwarf Pencilfish
Chili Rasbora
Phoenix Rasbora
Sparkling Gourami
Rainbow Gourami
endlers livebearers
Spotted blue-eye

I also really enjoy Betta's but I'm unsure if I could house them with other fish

I really want to do 1-2 "center piece" fish and a small group of smaller fish, and some kind of cleanup crew (shrimp or snails or both open to recommendations!)

I'm open to more ideas but these are the main fish I'm looking at

oh and any recommendations for substrate and plants would be greatly apricated, I want a really have green natural looking aquarium with drift wood as the hardscape. I want it to look time someone took a chunk out of a shallow part of a river!

I know all the basics like cycling and am a pretty big science nerd so I know all about the nitrogen cycle, just looking for recommendations for stocking and substrate/plants!

Plant recommendations for 5 gallon planted tank

I took the advice from you guys and moved my new 5gal cube onto my ikea bekant table. This should be more sturdy.

Here is my planted tank. The idea is to have a piece of wood in the center, with takashi carpet around it (my local fish store only had this, not monte carlo). The background will be tall pearlweeds and ambulias.

Do you guys have any recommendations for other tall tree like plants I could plant in the background?

Tightly schooling nano fish?

What are your faves? I'm revamping my 20 gallon and I would like a large school of small fish who like to move together vs. loosely shoaling or doing their own thing.

Frozen food and the nano tank

I've got a 25L tank, numerous shrimps, and recently added 8 tiny vietnamese cardinal minnows. With the fish in there now, I'm thinking about giving some frozen food.

The packs I see all look like quite a lot of food for so few small fish. I don't want to overfeed the fish, I don't want to just dump surplus food in there (even with the shrimp clean-up squad), and I don't want to waste it.

What are my options? The cubes will be difficult to cut up being basically ice. Can I defrost, split then refreeze? Are there nano-tank sized packets? Should I just go for live food instead?

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?
