My secondhand impression is that it will take 2-3 years to put on another foot but I'd love to hear firsthand experiences. I wish Arapaimag chimes in as he brought up more than one wyckii to adulthood but too often he appears to be too busy.
He has shown that he has done entirely to many thing right in the hobby not to take his experiances into account. personally my lil' guy has suddenly changed and become much more territorial.. i'm hoping this is a phase ( like what we went threw w/ our other cats in the 6"-10" range where the got suddenly extreamely aggressively territorial. He is deffinatly not happy when our good sized bigger fire eel pushes him around his hiding log. He was fine until the eel asserted its dominance.. and imo this may be the key to coming him in the future. he may need to be the "top dog" and have tank-mates not easily eaten. atm its pure speculation, but I will be trying this in the 56 w/ some other tank-mates and seeing if it might work.
