I bought a couple of groups of Mayan Cichlid fry at this year's OVAS auction. It appears I have a stowaway. They are now 5-6 months old and one isn't like the others. Can anyone ID this fish for me?(https://www.ovas.ca/forum/proxy.php?request=http%3A%2F%2Ffile%3A%2F%2F%2FUsers%2Fjeanguy%2FDownloads%2FMayan%2520Cichlid%2520fry.jpg&hash=168fafc1a2f00575502648e64fa53c661e85dac9)
