Good Companions:
* Peaceful Community Fish: Tetras, rasboras, danios, guppies, neon tetras, platies, swordtails, and most peaceful Corydoras catfish are good choices. They're generally not interested in eating snails.
* Larger, Non-Aggressive Fish: Angelfish, discus, and some larger gouramis can coexist with snails, especially if the snails are larger.
* Snail-Eating Fish (with caution): Some fish, like loaches, can be helpful for controlling snail populations if they're not overly hungry. However, monitor them closely and avoid species known to aggressively hunt snails.
Things to Keep in Mind:
* Snail Size: Larger snails have a better chance of surviving with fish that might nibble. Smaller snails are more vulnerable.
* Fish Temperament: Avoid aggressive fish, especially cichlids, which may see snails as a food source.
* Snail Species: Some snails, like apple snails, are too large for most fish to eat.
* Tank Size: A larger tank with plenty of hiding places for the snails will give them a better chance of avoiding fish.
* Feeding: Ensure your fish are well-fed. This reduces their urge to hunt snails.
In Summary:
Most peaceful community fish and larger, non-aggressive fish are good companions for snails. Avoid aggressive fish and monitor any snail-eating species closely. Choose snails that are large enough to avoid being nibbled. A larger tank with hiding spots for the snails will give them a safe haven.
