The white cloud mountain minnow, sometimes referred to as "WCMM" on the forum, is an extremely hardy fish that can withstand a wide range of temperatures. The WCMM can be kept in an aquarium without a heater as long as the temperature does not drop below 45°F (7°C).

They are peaceful and are suitable tank mates for a community tank as long as the aquarium temperature doesn't get too high. Many keep these minnows in small desktop tanks.

They will eat flakes, frozen, freeze dried and live fish foods.

White Cloud Mountain Minnow Comments

These are great little fish, but if you want peaceful fish these may not be the fish for you because these like to swim fast and madly round the tank.

From: Zygos5
These white cloud mountain minnows aren't peaceful little fish. If you keep only one in a small tank with other "prettier" fish like guppies... they will chase down the guppies and stress the blank out of them and do some damage to fins... They chase down harlequin rasboras as well... that's how peaceful they are! I like it when my harlequins chase and nip back! I'd keep white clouds in a school with other larger fish to keep them in line.

An excellent and extremely hardy fish suitable for all hobbyists. These WCMM are best kept in large groups as they feel more safe, when kept individually in a community aquarium they will chase other fancy looking fish as a defence mechanism. Have also found this fish is best kept in an aquarium with a light which enhances fish colours rather than a standard bulb, as this really does bring out its true colours!

From: Ronnie
Great little fish and very hardy, having survived an outbreak of Fin Rot which wiped out all my fancy goldfish but the white clouds are as healthy as ever!

From: Sophie
This minnow is a great little fish but keep a tight lid as they will jump out even if they seem happy. My fish are not too fast and do not chase any other fish. They are fine even with large fish like medium sized goldfish (10-15cm). Great fish 10/10 Excellent.

I have a small school (6) of gold white cloud minnows. I keep them with much larger fish, including assorted rainbows and Gouramis in a 55 gallon tank. They are indeed quite active, but really seem to leave all the other fish alone, including my smaller mollies and guppies. Very pretty little fish, and quite easy to keep.

Pretty and hardy little fish, but just a warning to Qld Australia viewers, don't put them in a pond. They are declared a noxious pest fish here. According to Officers of Queensland Fisheries, "White cloud minnows are exotic fish that have unfortunately become popular for mosquito contol. Native fish such as pacific blue eyes and hardy heads are much more efficient. White clouds may be kept in an aquarium, but are not to be released or kept in outdoor ponds where they can wash out during high rainfall. Penalties up to $150,000 apply to people who do not follow these rules."

White cloud minnows rock. They are extremely hardy, active, and have a certain spunk to them that is endearing. I had a group of 6 live 8 years. Most of the fatalities were filter incidents. who knows how long they would live in an undergravel filter tank.

Now I have a new school, also of 6. The previous group schooled in a 70 gallon tank. The new kids sporadically school about, but mostly roam the new 45 gallon at random.

Apparently, the males get into an interesting dance from time to time, fanning their red fins wide and circling each other. I suspect a higher ratio of females would make for a less boisterous lot, and you may see them school more then.

They lived well with a group of 3 Gold Barbs, which lived nearly as long as the white clouds. Did fine also with Mollies, including a homicidal silver lyretail. Seemed fast enough also to avoid any nips from Dwarf Gouramis, which although seeming slow, can move in an explosive burst of speed when they have the urge. Now the whiteclouds are alone in the tank again. Aforementioned homicidal Molly killed off several other Mollies, and the Dwarf Gouramis died suddenly.

They are a peaceful fish but can be hard to fins. Also they are very tiny and fast.

From: Beef
I got some the other day and they are great little fish. They like fighting against the current my filter creates.

From: 4WCs
These guys are hardy and wonderful for beginners... no question about how great these fish are!

From: Kathy
So far, one of my favorite fishes to keep. They are super active and real hardy.

From: Kat
I have 6 little guys and they are very happy in there big tank, they have tank mates - two rosy barbs but they all live well together. They are very peaceful fish and do not fight or scare other fish.

From: Eddy
White Clouds are the best fish that I've ever had. Great starter fish and a great community fish. Once they get used to the tank you can even hand feed them.

From: Ash
Great fish! I have 30 or more and lots of babies. They are great with other fish and great in both tropical and coldwater, but dont keep with goldfish, some fancys are ok. If you want to breed them get a small plastic tank, some gravel and lots of plants or just some java fern or moss. Lowering the temperature and feeding more live food will trigger spawning. Eggs are laid among plants and gravel. Eggs hatch between 22 - 48 hours.

From: Kass
These guys are almost too peaceful! I kept them in a tank with Guppies and one of the male guppies chased them and bit large chunks out of their tails. This stopped when I added about 8 more (origanally 7). I almost think the guppy was trying to mate with them (although there were other female guppies in the tank).
