Frozen Food

Hey! Recently I bought a pack of frozen Silversides for my Mudpuppy, but I left them out overnight. I know this is really stupid, but could I still use them without harming the Mudpuppy? Thanks!
 
Dead fish grow bacteria really quickly. On a fertile medium, overnight is enough for a single bacterium to produce a colony large enough to see with the naked eye. I think it would be a bad idea to use them.
 
I work for a manufacturer of frozen fish foods for aquarium fish and this is what we recommend when frozen food thaws.

Use of Frozen Fish Food That Has Thawed

  • You may safely refreeze some foods that still contain ice crystals and are cold to the touch or if they have been kept below 45 degrees F for no more than 2 hours. If the temperature is above 45 degrees F, THROW IT OUT!
Treat completely thawed foods as follows:
  • These foods are perishable. Do not refreeze thawed fish food. Spoilage may begin before bad odors develop and may be toxic. Refreeze fish food only if ice crystals remain throughout the package. If you question the condition, THROW IT OUT!
  • Don't use if odor is offensive or if the freezer temperature has exceeded 45 degrees F for 2 hours or longer, THROW IT OUT!
Use common sense: If any foods have an offensive or questionable odor, DO NOT feed them to your fish.

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
