I traded in a bunch of large fish today at my local cichlid dealer and he had some 2 - 3" Gymnogeophagus 'Arroyo Yerbalito.' I've never kept Gymnos as I'm not a big fan of the nuchal humps, but these guys really stood out to me. He showed me a larger sized male in another tank that had gorgeous deep red fins and lots of blue spangling. He was a very impressive fish for his size. I was offered a pair of the smaller fish for free.
So a few questions:
1) It seems from Googling that there are a couple of species of Gymnos from this river. Can anyone tell me which one this probably is? The fish shows no yellow at all; just a deep red and blue. I'd never seen red like that on an SA cichlid before.
2) Is it true they're harem spawners? If so, how many females should I get and what size tank would I need? What is their maximum size? Does the male develop a really big nuchal hump? Also, can they be sexed at 2" easily?
3) As I mentioned, I've never kept Gymnos so I don't know anything about the cool-down period. I live in Florida so even in the winter it doesn't get too cold. Is there a minimum temp they need to get down to? I could probably get their tanks into the low 70s, but I doubt I'd get it any lower unless I kept them in the garage or put a chiller on the tank (which I don't want to do).
4) How common/uncommon are these guys? I've never seen them locally, but that doesn't say much because we don't get a lot of nice SA cichlids here. Are they a dime a dozen?
