Rainbow Detective Needed


Recommended Posts

Hi everyone. 

today at my LFS I bought two medium small size Rainbowfish, the store said they had been shipped in with Diamond tetras and had no idea what they were. What do you guys think?

I also posted some pictures of my other bows for fun in case anyone wants to play an identification game. ūüôā

(1) ?? Not sure ?? Melanotaenia fluviatilis Could be!

(2) ?? No idea ?? 1&2 are the mystery fishies  

(3) ?? Not sure ??¬†Melanotaenia trifasciata¬†Ironically this was sold to me as an Aussie! ūüôā¬†(M. fluviatilis)

(4) Melanotaenia caerulea M. lacustris

(5) Melanotaenia praecox Yup!

(6) ?? Not sure ?? Melanotaenia trifasciata 

Last one is tricky since it’s adolescent/juvenile Glosolepis Incisus


I didn’t know about the caerulea, looks like a neat fish.

Turquoise rainbow fish is 4th pic   Neon blue rainbow 5th pic not sure about the others 

Right on. I’m wondering if the mystery rainbows (1&2) are just Australians with unique colors, or maybe even hybrids.
