Hi, I do not think a pig liver is a good choice for several reasons. First, liver is a disposal gateway of the organism and hell knows if any of these are harmful to fish, especially fish so gently as rams. Second, pig liver contains quite a lot of fat and carbohydrates (I know it first hand as I tried to isolate RNA from it - what a mess). Clay color is from this. Third, liver will contaminate water much more than anything else.. Beef heart - good, proven, hi protein, low fat, will contaminate water, but to much less extent. Cooking 1. raw, chopped with blender fine particles made from de-fibrinated (sp?) pieces (or whatever you call these things no one can chew on?). Can be frozen and kept indefinitely. 2. To minimize mess, I add some agarose or gelatin to #1 to bind blood, and very fine particles. Also can be frozen. #2 is a favorite food of my rams, no side effects of almost everyday use for the third generation. PS. Thinking of other sources of meat - beef tongue should also be fine, but is rather expensive.. Raw fish or shrimp, too Cheers Lilia On Fri, 25 Dec 1998, Andrew Ivanyuk wrote: > Hi! > So, today I tried to give my fish a little bit of boiled pig liver at > first time.
