sorry to hear about the losses.
leopard wrasses quickly became one of my must-haves when i got back into reefing, and started sorting my wish list. sadly, i also lost a pair of black leopard wrasses (they didn’t even make it out of quarantine).
i’m aware of their penchant for hiding sometimes up to a week when first introduced. i remember trying fresh clam or shrimp juice, etc. (just a few drops) ... something that would prove too irresistible and encourage them out of hiding. i guess it really depends on the individual personality of each fish.
this thread gets me wondering now if there’s a preferred entry order within the Macropharyngodon genus (when it’s not possible to introduce all the target M. species all at once). ;Bookworm
