I put in a Volitan, about 6" at purchase, in my 75 gallon tank which also housed 1 adult yellow tang, 1 adult polychromis, 3 juvenile domonos, 3 yellow fin damsels, 1 coral beauty, 2 clowns and a couple of "trash" fish who will remain only fond memories. This was about 8 weeks ago. I was very concerned in that the lion fish simply would not eat any sort of frozen food. I introduced an occasional feeding of ghost shirimp or guppies, and indeed, the lion did start eating. The trouble is, he hasn't stopped since the introduction of live food. The other remaining inhabitants in the tank also have converted to live food eaters. I never thought a tang could be so aggressive! The dominoes are the scarriest. One has grown to about the size of the adult tang, which has to be an anomally, but accompaning his rapid growth, he's become very aggressive. The lion fish stays clear of the domino, if you can believe that.
Only the damsels and trash fish have fallen prey to the lionfish, however the coral beauty is questionable, and rarely ventures out of her hiding place. When it comes to live feeding, the lion will eat everything I put in and then some, but the other inhabitants compete for the grub, in a more and more aggressive manner. Yikes, I wish I had never introduced live feeding.
I have set up a separate "menu" tank, so I always have an abundant source of various blue plate specials (some of which are notably larger than the conventional ghost shrimp or standard guppy), but I'm wondering if there's something I can do to initiate the lion to eat some frozen food, and greatly reducing the number of live feedings. I now feed live about every 4 days, (frozen or pellet for the others every 2 days) and I probably overfeed in the live feedings. The lion eats everything introduced that the others don't scarf, and he then retreats with a belly that looks like a mongolphier hot air baloon, to his usual perch, upside down in a corner, head facing the bottom of the tank...looking for more prey. Oh yes, I forgot to mention lions do grow fast, this 6" little beauty is now over 8". All in 8 weeks!
Any chance I can reverse or at least curb this guttony?
