Can Fish Get Sick From Frozen Food?

I just got some San Fransisco Bay Brine Shrimp frozen food, and I was wondering if anyone had ever heard of this (or any other frozen food) causing fish to get sick. I've heard some people say that it can, while others day that it won't. I just want to make sure that I'm not getting my healthy fish sick.

Also, is it true that thawing and refreezing thet food will make it poisonous?

 

Dear CMB

I have Omega Brine Frozen Brine Shrimp, and it seems to suit my guppies just fine. I haven't heard of San Fransisco Bay or Omega One food getting fish sick. I also thaw and refreeze my food, and it doesn't seem poisonous to my fish.

San Fran’s Isco bay is what I use to supplement feeding with my fish. The only time it makes fish sick is if you only feed frozen food. This will lead to vitamin deficiencies and an early death as a result. Just to comment I don’t recommend reframing food. During the process of thawing and then refreezing the food loses a lot of its nutritional value and as a result loses the main reason you’re feeding it to your fish. So no it doesn’t make it poisonous but it does lose a lot of what makes it healthy.

 

From what I understand, thawing and refreezing can result in harmful bacteria forming as the food heats up.and thaws. Obviously it matter how long it was left out but it's best to just avoid it and toss.the foood if you left it out.

Frozen food should be fine but if you're really worried, go.woth Hikari. They claim to use a three step process to ensure their product is parasite free. Also, if you really the labels, HikarI adds vitamins to their frozen while SF Bay doesn't.

 

Thank you guys so much for your help. I went ahead and gave my fish some frozen food yesterday for the first time, and they seemed pretty happy about it. The gouramis didn't seem to know what to do (the food sank too quickly for them), but all the other fish loved it. I will make sure not to thaw and refreeze food, just to be on the safe side, and I will definitely consider getting some HikarI frozen food (I have some dry bottom feeder pellets, and they seem pretty good). Really, I think that I'm being a bit paranoid to ask, but I want to make sure that I don't get my fish sick.

 

I put a cup of tank water in a disposable plastic cup and add the frozen shrimp for 5-15 minutes. Then feed.
