Not lah bro...me ain't a guru lah, just sharing my experience with frens over here and hope it helps. But the good news is...my lions have gone to 8" and they have been in captivity for almost two years now:) I recently acquired a yellow frogfish which i just managed to wean it to frozen:) and this time round its only half the size of my lions:) Keeping my fingers cross that it ain't a stupid bugger for another "lions attempt". I know i'm pushing my luck a little but hey, wish me luck.
