fish for a 2.5g nano

Hello everyone. I have a little 2.5g planted tank and wanted to add some fish to it. I was thinking of some white cloud minnows. just wondering how many i could comfortably keep in this tank. it is being filtered with one of those red sea nano filters and water temp stays at 76-78. thanks in advance

I have fish in my planted 2.5, have had since I really planted it up about a year ago. Green neons are an excellent choice, they seem to stay smaller than neons, and provide that famous neon color. A number of killies are great choices as well. Aphyosemion striatum comes to mind, as does A. australe or A. bitaeniatum. Pretty much any coastal-lowland Aphyosemion sp. should do pretty well. Some small lampeye killies (Poropanchax spp.) are also good choices, but can be harder to find or recieve healthy. If you're looking for catfish, I am a fan of cories and have Aspidoras sp. "Black Phantom" in my 2.5. They're active little guys and lots of fun to watch.
I dont have small rasboras like B. merah or B. briggitae, but can't see them being poor choices. Neat little fish. Dario dario was one I saw in Germany that looked very nice in a small planted tank.
There is a sticky that has lists of good tiny fish for tanks like this, check it out, it's more complete than I am here.

No green neons or white clouds in a 2.5 gal please! If you want fish make sure the tank is heated densely planted and maybe 3 micro rasbora or celestial pearls, maybe even some green Kobotai, ember tetra or one sparkling gourami. I have 3 microrasbora maculta and rcs in my 3.5 gal and they are fine. The micro rasboras I have are the same size as the RCS.

I have 6 Least Rasboras in mine.

Definitely no White Clouds though, they get around 2" and are VERY active.

10g minimum for white clouds. but make sure theyres a current, they loved to play in the strong current in my 20. in the 10 they were mellow and just floated because of the slow moving water but when it was fast in the 20 they really perked up, showed their brightest colors, and were really fun fish to watch. i only got rid of them because they would bully my boraras and shrimp. and put only a betta in a 2.5, i guess its better then dying in a cup.

Actually, they are different fish. Celestial Pearl Danios are just that, DANIO's. The microrasboras are usually in referance to the Boraras species of Rasboras, ie. Merah, Maculata, etc.
Alo, I would not put any of those fish into a 2.5gl tank...ever!

2.5gl is the empty volume. Once filled with substrate, hardscape and plants, open swimming space is greatly reduced. even if the tank was empty, 2.5gl is not big enough.

I have CPD's and microrasboras, B. Merah, and both of them need to be kept in schools of at least 7, and both are active fish. Not super crazy like some danios or the whiteclouds, but still lively.

To keep a small school (and I use 'school' generously as 7 is not really a fair number to be considered a school, so from now on, it'll be called a group) of any of the Boraras or Danios, or even green neons or a similar shoaling fish, the minimum would be 10gl's.

For a nice desk-top 2.5gl, shrimp are wonderfull- they are curious, colourful, cheap, and have a very low bioload.

I, along with many other seasoned hobbyists are very glad you asked this question on here. Hopefully others that are wanting to set up small nano tanks can read this, and the other similar posts and can come to a reasonable and ethical stock list for their tanks.

Good on ya tiger!

I'm curious here...
"ethical stock list"...can you define this?
Here's why I say it. I recommended fish like green neons and Aspidoras above, because experience tells me that it is an acceptable setup. I've had the green neons in this setup for very nearly a year now and everyone who's seen the tank would not deny that the fish are healthy. That tank has been complimented by folks like Cory at Bayleesfishees. It's a kick-butt tank, in my opinion, and most folks share that thought. These are people that wouldn't if the fish were unhealthy in any way.
But your post seems to say, to me, that my stocking is perhaps "unethical". Is this so? See, I'm not a fan of the "rules" of fishkeeping, but I stop bending them when it becomes detrimental to my plants or animals. I hope odleon knows this, and that if the tank is well cared for (water changes!), a planted 2.5 gallon tank can certainly house a few fish.

fishboy I think your green neons stay small because there growth has been stunted. They don't stay small. My green neons are in my 120P (about 65 gallons) and they are the size of cardinals. Im talking about Paracheirodon simulans they grow to one inch. As far as ethics, most fish that are kept in aquariums can be said to be unethical. They are not exactly kept in there natural habitat. I am guilty of this also. Green neons live in the Orinoco river in dimly lit pools, while i keep mine with 300watts of metal halide lighting. Although I only keep the lights on for 5 hrs a day. I still say only keep micro fish in a 2.5 gal tank.

Fish, such as Whiteclouds, Green Neons, Cardinal tetras, etc, when bought young, or when hatched young and kept in smaller aquaria do tend to get stunted, and do not reach their full growth potential.
Shoaling and schooling fish need ample room to stay healthy and happy. A shoal is not three or four fish.
Now, I have not seen your tank with the Green Neons, and do not know your fish care/keeping habits, so I can't make a call on that, and I haven't yet. You do raise a good point though: water quality.
A tank of his size, the afrementioned 2.5gl, is going to need careful monitoring.
I'm sure you monitor yours and keep up on the w/c's, which is good.

I'm not trying to start an online fight here. Thats not me in anyay. I'm just saying that when it comes to selecting fauna, that one chooses it accordingly to tank conditions and livestock requirements.

Oh Ok. i had looked the CPD and the micro maculata on google and they came up with some of the same pictures. Also, the white clouds are on the sticky for nano tank fish. i really dont consider a 10g a nano. I consider something like 6-7g to be nano-class. thats just me tho.

Thank you for that. I, too, am not in search of a disagreement. I often ask people to define what they mean so I avoid a misunderstanding, and I appreciate your response with a pretty clear idea of what you mean.
On a side note for marimo...my green neons are pretty close to that size. Cardinals are a slightly larger fish, I believe they are the largest Parachierodon (Fishbase agrees). Oh, and BTW...nice lighting system .
