B1 and B12 supplements

I went to a presentation at the Vancouver Aquarium last night by a senior aquarium biologist named Jennifer O. Reynolds. She is a specialist concerning freshwater stingrays and currently oversees the population of 23 different rays (of several different species) at the Vancouver Aquarium.

She provided an overview of the freshwater stingray keeping strategies used at the Vancouver Aquarium. Most of the strategies she noted are already well known on this forum (use of PVC pipe to help with target feeding specific rays; need for three or more feedings per day for pups; need for sump or sand filtration of water and frequent water changes, etc.). One strategy that was new to me, however, was the use of B1 and B2 liquid supplements for injection into a stingray's food of shrimp or freshwater smelt. It has to do with thiamanese and the breakdown of B1 and B12 that occurs after 3-6 months of fish/shrimp being frozen. Someone asked if the supplements were available for hobbyist use and Jennifer responded that she did not know. She did say that commercially available gel foods (I am guessing Repashy?) and maybe other pellet foods can also provide the supplement (depending on what is on the ingredient list). I am going to do a bit more research and try to find the injectable liquid supplement.

Boyd Vita Chem is a supplement that I used to inject Superworms. Just stick the worms in the freezer for a minute or 2 prior to feeding so they don't wriggle so much and then inject them with vita chem. They blow up like a balloon , my kids loved it. You can also soak your MP or fish in it.

When I bought my first ray years ago the wholesaler gave be b1 tablets to add to water for the pup. I used them for a few months but never continued after that. I wonder if I should dissolve and throw in my food while thawing

I do know that the Vancouver aquarium has been using Repashy foods since the testing phase and are still using it.

I've still got a bunch left too if anyone is looking for some.
