ya i saw that too brian.. but in the list of fish without thiaminaise there is a crustacean list.. has marine shrimps and portuguese crabs.. and further down.. there is a "How can I avoid the thiamine deficiency syndrome?" pt 2. Avoid feeding exclusively frozen bivalves or shrimps, because these potentially have very high thiaminase content. says exclusively frozen.. lil confused if frozen or shrimp is the catch here.. my aros eat frozen prawn reluctantly.. but the minute i give them fresh they go crazy..
 
hmm didnt saything about butterfly shrimps? or are they categorized as tiger shrimp?
Brian is right that note about the prawn and shrimp is a uh-oh... lol


btw kaya nice find! it was a good read :D

Yes I see that,
Marine shrimps (sp. indet.; Hawaii)

which looks to be
Whiteleg shrimp (Litopenaeus vannamei, formerly Penaeus vannamei), also known as Pacific white shrimp, is a variety of prawn of the eastern Pacific Ocean commonly caught or farmed for food. http://en.wikipedia.org/wiki/Whiteleg_shrimp

Which is what is labeled on the packaged shrimp I feed. Looks like alot of the cheap seafoods many of us are feeding to our fish are not good.
 
whoa good information, i feed my fish prawn once or twice a week on while they will have hakari pellets as their main food..and i do not plan to change their diets. its GOOD after all within acceptable amount and balance is the keyword to look for.
 
True Brian.. I didn't want to cause a scare but its better being aware.. anyway i found another link..

http://theaquariumwiki.com/Thiaminase

a little discrepancy in this.. they list hake as thiaminase free but the earlier link includes them.. there are a couple more links at the end of this link i've given now.. tilapia is on the list of not containing thiaminase.. so thats one thing right.. but i'm still bothered bout the prawns..
