Mixing WCMM breeds

[Native Keeper]

Hello everyone!

I've recently found myself in an interesting situation.

Currently, my grandfather has 6 Golden White Cloud Minnows in a 29g tank. I have noticed that some of them are fin nipping, which means that there isn't enough members to disperse aggression. However, the only place where I can buy GWCMMs (Petco) has seemingly stopped carrying them at the store. But I have a solution, but I want to check with yall just to be safe. 

my local Petsmart frequently carries regular WCMMs. So I'm think I'll buy him some of those instead. Though I am slightly concerned that it may cause issues since they're different morphs, so here's my question:

can you mix different colored WCMMs? Or will it cause issues?

@WhitecloudDynasty will be most qualified to speak on this.

In my view, the only cautions I’d have about mixing strains is diluted color-purity of offspring.

I agree with @Fish Folk .  My understanding with WCMM is they are the same species but different strains similar to guppies or medaka so the only issue would be in the purity of their offspring.

Thirding that.  Only issue might be crossbreeding, but in a social group they should work out just fine with one another.  I've seen them kept together at LFSs, both the gold and regular WCMM in the same tanks for sales, and from what I've seen in that situation, they appear to readily shoal with one another.

They are the same fish, but if you do breed them the gold are recessive so you'll get more regular color one.

Just a fun video on the topic.
 

I would encourage you to check out aquahuna to get some more white clouds if you really want the normal variety 🙂

I recently got some golds to go with my regulars and they all intermingle just fine. They seem to appreciate the company. There was a decent amount of sparring between males as they figured out the hierarchy, but no actual violence.
