The gist of my post was (and my opinion has not changed since 1st saw them in the early 90s) and now, is to point out that this is not a true species.
I believe some people think this fish just happened somewhere in a remote eden..
No, it was manipulated into being, no differently than balloon goldfish, or goo-fish, and in my book, is no different, kind of like auto tuning someone who can't sing in key.
If you don't care you are buying deformed, scrunched organ pseudo-cichlid no problem.
But if you think its some sort of natural species, think again
