Hi there.
I have a histrix, and soon i will reccive a wild cought female leopoldi (p13).
I feed the histrix earthworms, shrimp, raw coalfish, mussels and mysis, but recently i have been reading about ppl who say that "you need to give your rays additional vitimins"... it have made me wonder.. And i have done a lot of searching on this topic, lately... without relly getting anywhere...
If thiaminase is so dangourus to predatory fishes, sutch as stingrays, how the * do they survive in the wild? I understand that rays feed alot on different types of crustations and mollusks in the wild... and that "fish" generally is only a smaller part of the diet to most rays (am i wrong?). So culd these problems ppl are talking about, with captiv specimens, be due to the AMOUNT of fish meat we are offering them? In that case; culd the solution be to just cut down on the fish supplies, and feed more crustations etc?
... or do we still have to offer additional vitamins?? One thing i do know - in the wild, humans are not swimming around, injecting vitamins into ray-foods..
More questions to come. I am having a hard time writing in English, took me 30 minutes to write this. So need a break
