jay... i hope you dont feed you fish dog food....
For me i want the convenience and what is best for my fish... and of course try something new...
althou hikari is abit expense but you cant compare that to dog food? with that thinking wouldn't hikari, NFS and other gone out of biz by now...
2pound of shrimp = 2 pounds of pellets?

you forgot the % of water in the shrimp... wonder how much 2 pound of "Freeze Dried Shrimp" will run? lets not forget the vitamins and nutrients in these pellets...
example on jehmco.com
Frozen Krill, (sp. E. superba), 2 kilo. (~4.4 LBS.) $20
Freeze Dried Krill 2 kgs (4.4 LBS) (not screened) $90
i do have 5 gallon bucket worth farm trout pellets... they are extremely cheap but i dont think they are suitable for home use... not only they cloud up the water.. they make your water oily also....
but it still up to the fishkeeper... to feed what he/she think what is good for the fish...
