Caught them dancing last night, and I have females two holding as of today. I just got these 8 on Jan 21st. They are in a 5 ftx18x26 inch tank with 16 Petro Ortho Ikola juvies. They are a great fish, my first Gobies. I hope to see some babies as I have lots of hiding places in the tank. Here is a pic of one pait of proud parents. My photo skills do not show these guys off!
