Long story short (involves a kitten and a tank without a top) my 12 gallon will be fishless this coming week. I will have my 55 gallon up and running in about a month or 2. I will be returning the 2 Kenyi I bought(before doing my research) and was considering buying a few juveniles to have in this 12 gallon, maybe 4. I really like these fish, the Cobue variety. My questions is at the LFS how can you tell what is a Cobue vs. different variety? They are labeled with their scientific names vs. nicknames. I just don't want to purchase the wrong type and the cichlid 'expert' isn't always there so at times the employees really don't know one from another. What should I look for? Any thoughts? Thanks.
