jamesscott, what do you say about the research that shows that gold fish have high level of thiaminase?

Well let me say a picture is worth a thousand words would you like me to take some pictures of my pike with a ruler beside him? How about I take a full tank shot of the fish that are with him who although they do not get a steady diet of feeder fish do not seem adversely effected or affected by the goldfish I have fed them.
There is also the youtube video of a petshop with it's 15-17 year old pacu who most definitely was not stunted by it's diet of nothing but feeder goldfish.
I would reiterate the words GUT LOADING, mixed with a healthy minimum month long quarantine period for any feeders I feed my fish.
Here is the list of ingredients on the back of the food container I have in front of me that I feed.
crude protein 38.1% min
crude fat 9.7% min
crude fiber 2.8% max
ash 10.5% max
moisture 14.5% max
protein as a % of dry matter 44.5%
fat as a % of dry matter 11.3%
ingredients in order of appearance. Shrimp meal, Euphausia pacifica plankton, Sardine meal, kelp, alfalfa, squid, salmon egg oil, spirulina, fish oil, garlic, minerals (calcium chloride, potassium iodide, ferrous sulfate, manganese sulfate, manganese carbonate, zinc sulfate) MPAX tm (Marine Protein Amino eXtracts. hydrolysates, select amino acids(arginine, histidine, isoleucine, leucine, lysine, methionine, cystine, phenylalanine, threonine, tryptophan, valine)) Vitamins(stabliized vitamin c, biotin, cyanocobalamine, niacin, riboflavin,
thiamine, vitamin E) Preservatives (ethyoxyquin, potassium sorbate) Carotenoid pigments (astaxanthin, canthaxanthin), and beta glucan.
Take note NO WHEAT, CORN OR SOY

as well take note of the word in red in the ingredients.

And when your study of goldfish comprises feeding them a high quality food for a elongated period of time I would place my trust in it. There is a saying that I go by, You are what you eat. I believe that the same would not only qualify for feeder fish. As well the end result of what my fish look like speaks volumes that they are not stunted by a growth inhibiting hormone present in goldfish.
If you wish I will take some pics of the fish in my 300g who have had a diet supplimented by feeder gold fish.
