Gymnogeophagus Ex Meridianalis Help Needed

[SuperGuppyGirl]

So picked up 6 of these little beauties at the auction and need more info on them. The net is surprisingly (not) unhelpful besides a lot of posting on name variations. I know they need a cool period of 2-3 months, are a cool water species but really nothing else on their specific needs. Any one have these that can share their experiences? Comparability ? Sexing? Especially how many in a 75G tank. Thanks in advance.

Most Gymnos are like other SA cichlids - plants, caves, rocks, good food, good filtration. They just like cool water. Your 6 will be fine in a 75 for a while, but I'd imagine things could get dicey when they start to pair off.

How would they be with a pair of kribensis in the tank? I moved out the bettas females so just have some guppies, the kribs , Cory's and a few twig catfish.

Try it and see. A breeding pair of kribs might get too pushy, but there should be enough space for now.

Going to give it awhile, thanks Jason

Here is a quote from an email from Spencer Jack, he collected these with in 2009.

"......Fish needs a cool down period for long term success and viability. so at least 3 months of the year where about as cold as you can, slowly take them. ideally around 10-12C. feed like once a week when they are in this state. Then slowly bring them back up past seventy and this is when they usually will spawn. if you keep them hot all year round they will burn out."

Hope this helps.

It does! Couldn't find anywhere what temp to lower them to for the cool down period , thanks Jayba.

Sounds like they might be an ideal pond fish! Toss 'em in the garage when everything is thawed, then when overnight lows reach double-digits, send them out! Bring 'em in when all the leaves are gone!
