Blind cave fish...eyeless or not?

  • We are currently upgrading MFK. thanks! -neo
Research has been performed that showed breeding seperate populations of blind cave fish actually brought back some tiny eyes. the populations evolved seperately(I believe) and breeding them back to each other apparently corrected the problem. There are so many genes involved with even just the eye that the alleles that depraved different populations were different, so cross breeding them brought back the allele that the other population was missing

In short words, the tetras I saw today must be the hybrids between two populations. I learned something new today!
 
Another excuse to set up a 10gal tank for these eyed cave tetras!
 
I do believe the research was fairly recent, so who knows what you can do if you grab those and breed them with other populations of eyeless. A fun breeding project. The hard part would be trying to get fish from populations you know to be different

Might be time to plug in the Rapps Signal.

It is very interesting and a very concerning subject at same time since now there are populations that is genetically different from each other. That means the blind cave tetras in the aquarium trade have mixed & unknown orgins and the importer/exporter probably don't keep the records of the true orgins that orginal broodstock come from.
 
Wow the blind cave tetra, kinda forgot about those guys. I had some back in the early seventies in a 20 gallon and remember three out of the five I had got to 4 inches and incidently had no evidence of eyes but these guys were as fast as giant danios. I think I will try to find some again as I remember for a blind fish they were incredibly fast.

Make sure you check out them to see if they have eyes or not!
