Well I’ve learned that the Siniperca obscura will take frozen krill with little or no help while the Siniperca roulei won’t take frozen krill but will take frozen rosy reds. Given the similar color of rosy reds to krill I believe it’s only a matter of time until I can get them to eat krill, the way they look at it seems like they acknowledge it might be food but are to hesitant to go for it. I will have to cut a little width off the krill for the Siniperca obscura because they struggle a good bit with an unaltered krill but can keep it down which I want to make easier on them.
