How many White Cloud Mountain minnows in a 20 long?

[DustinJWagner]

Hello! I am going to be doing a planted species only tank of long fin white cloud minnows in my 20 long. There seems to be a lot of varying information out there as far as stocking, what would you say is a good number of these fish for the 20 long footprint? Thank you!

Is it only going to white clouds in this tank or are you having some bottom dwelling fish 

[DustinJWagner]

Good question! I have one bristlenose in the tank.

I think 10-12 would be ok in 20L as bristlenose produce a lot of waste  I wouldn't put more than that unless your prepared to do extra water changes

I’d say a dozen seems about right. Is the tank planted? If so, it’ll be fairly easy to keep 12 or so with a BN pleco. PS you’re going to love White Clouds, they may be the most underrated fish in the hobby. Maybe. Enjoy. 
 

I just reread and since it will be planted, you will be fine, enjoy.

White Clouds are pretty low bio load fishies. I think you could top out at 20 or even more if you’ve got fast growing plants to remove the nitrate in there. 
 

20 Long is one of my favorite form factors. It is the perfect balance of swim length, space, and cost for smaller critters. I like 33 Longs and 75 & 125 reg for the same reasons. 
 

I have 2 normal fin white clouds in my unheated 1 gallon heavily planted office tank, and I will reiterate that they are one of the most underrated fish in the hobby. Beautiful colors when healthy, and their displays and behavior remind me of little Rainbowfish. 
 

good luck, take pictures!
