[lbpuente]

Hi!! Does any body know what type if rainbow fish is this. I need to find him/her a mate.

Thank you for your help!!

Pretty sure it's a Preacox.

 

[lbpuente]

Can you tell if that is a male or female?

 

[Bichir Bro]

Now this I'm not 100% on. It looks to me like a young male however I may be wrong on this one.

 

[Mebbid]

If its a praecox it is a female however I don't believe that it is a praecox. I've never seen them with the line down their body

 

[Bichir Bro]

It may be an eastern rainbow fish.

 

[pip walters]

I believe it is Melanotaenia splendida - the Australian rainbow

I believe it is Melanotaenia splendida - the Australian rainbow

Agreed, looks like a male Australian

Or possibly a macculochi who hasn't coloured up yet

 

[TheCommunityCichlid]

I'd say Australian rainbow

 

[lbpuente]

[TheCommunityCichlid]

One usually reliable way to sex rainbows is to check the length of the first dorsal fin. If when folded down it reaches behind the start of the second dorsal fin (as it does in your fish), then it's likely a male. As for species, it's definitely an Australian rainbow (member of Melanotaenia splendida complex), but is most likely of mixed origin (a hybrid).
