Freshwater feeder fish causes issues?

[Picasso the Triggerfish]

It's true that freshwater feeder fish causes issues to predatory fish like a snowflake eel? Which saltwater feeder fish is a great alternative to feshwater feeder fish? This also applies to ghost shrimp?

I dont see a need to feed a snowflake eel live food, except maybe in a few exceptions as a new addition. And in that case ghost shrimp or even a fiddler crab for a larger eel is a fine selection. A peppermint shrimp from an invert only system is fine as well, although expensive.

Mollies, guppies, and ghosties are the choice in live foods regardless of what youve read or heard. Ive kept predator fish including lions, scorps, ribbon eels that do better on live foods for 10 years or more feeding these foods as their main diet. Usually people you hear these things from have never kept these fish successfully.

Using any marine fish as feeders is a high risk to spreading disease. Even if qt feeder marine fish has been treated, you would be feeding poisoned fish to your pet. Other fresh water feeder fish like goldies and rosies are high in thiaminese which binds vit B1, and gold fish may have too high a fat content.

I wouldn't feed a live animal to another one because I feel bad for them lol, unless it was to entice the animal to eat silversides, krill, and maybe some mixes will be fine for the eel
