Nutrition Sticky

  • We are currently upgrading MFK. thanks! -neo
As Sm0ke just mentioned, there are foods that we can feed that are low...like salmon.

Just weird that P nutrition forum goes both way on shrimp, and also endorses pellets, made essentially from the things they tell you not to feed in the whole.

Im starting to lean towards the thiaminase thing not being an issue or a myth.

Trying to get someone from my university to weigh in on it, but the person I thought could help me declined.

I make a SW food - and Im currently feeding my baby natts a mix of different things...they have doubled in size in just a couple weeks...these guys are amazing.

Just wish that feeding them to bursting and keeping them with almost 50 dithers was enough to stop them from beating each other up. Today I woke up to find one with a bite in his eye... :/
 
Im starting to think that this thiaminase thing may be much ado about nothing.

If one is feeding a balanced diet, one that contains ample amounts of natural forms of B1, or is supplemented with vitamin B1, then thiaminase becomes a non issue. High quality pellets such as NLS would fall into that category.

Great thanks. For my fish that don't eat pellets, I stuff prawns with nls pellets and give them that so hopefully that should be an ok diet.
 
I've been reading up more on it, you can apparently get rid of thiaminase by cooking, you'll probably destroy a lot of beneficial nutrition doing so though.
I guess if you supplement vit B1 you really don't need to worry. I make my own DIY food too using a method sm0ke posted on another forum, I'm going to research veg that is rich in B1 or add it direct to the mix using vitamin tablets.
 
Thiaminase is simply an enzyme, and yes heat will destroy it, while freezing will not.

Theskibag - stuffing raw/frozen food with NLS pellets will work just fine. That, or one can add a vitamin supplement. When I fed fresh/frozen I presoaked the food in Boyd Vitachem which contained (or at least did when I used it) an ample amount of B1.

Thiaminase is not a myth, and while the science regarding each & every species of ornamental fish that's kept in captivity may not be available, there are easy workarounds to resolve any potential issues from B1 deficiencies just as there are for all of the other potential vitamin & mineral deficiencies.

Thanks again RD. Yeah was thinking about getting a vitamin supplement
 
I've posted a link to the following paper a number of times over the years, for anyone that feeds fresh/frozen you might want to read it. Both the authors & those that reviewed the paper hold PhD's in the related sciences.

They also mention thiaminase, as well as other potential vitamin/mineral issues when feeding frozen food.

Very interesting.

I use vitamin supplements as well - any tactics you guys use for soaking it up?

I am considering essentially making shrimp jerky, and then rehydrating it with vitachem. Thoughts?

Also might try nls stuffing when the P's get a little bigger. Definitely want them on pellets.
 
I made some gelatin based (shrimp/pellet/vitachem/garlic/white fish) cubes, definitely the easy way to feed P'S.

Almost out of it too so I'm going to be making a new mix in a few days, going to try some different ingredients. Reading up on giving fish protein powder too, not a lot of material out there but quite a few discus breeders mix it into food and get great results.
