Can goldfish be raised with small conch?

Of course not. Don't listen to those two nonsense upstairs.

Goldfish is a freshwater fish, conch is seawater, and the two cannot be kept together at all.

Conch cultured in fresh water will only die. After the death of conch, it will make the water quality worse, and it will also affect goldfish.

So don't put conch and goldfish together.
