Cryptoheros nanoluteus Care

There isn't much about this species on Google. I'm assuming that these fish aren't as mainstream as alot of other species However I had a small window of opportunity to grab some and they'll be here tomorrow. I have an Electric blue jack Dempsey in the tank he's only the size of about a fingernail is it possible that I can keep these together? Also, Any extra information about this species would be greatly appreciated and if you've kept these I'd love to hear about your experience. I believe that this is one of 3 I will be receiving as this what was in the Sales Ad
