Here's why:
* Predation: Catfish, even albino ones, are carnivorous or omnivorous. While they might not actively hunt guppies, they can be opportunistic eaters, especially if they get hungry. This means there's a risk of them snacking on smaller guppies or their fry.
* Competition: Catfish are bottom feeders, and they can outcompete smaller fish for food.
* Stress: While some catfish species are peaceful, others can be aggressive, especially if they feel threatened or stressed. This can lead to bullying or injury of smaller fish.
So, can you keep them together?
It's possible, but it depends on several factors:
* Catfish Species: Some catfish are more peaceful than others. Research the specific species of albino catfish you're interested in and their temperament.
* Tank Size: A larger tank gives more space and resources for everyone, reducing competition and stress.
* Community: A balanced community with a variety of fish that can coexist peacefully is crucial.
* Feeding: Ensure all fish are well-fed to minimize the risk of predation.
Instead of guppies, consider these tank mates for albino catfish:
* Other catfish: Many catfish species cohabitate well.
* Larger tetras: They're more robust than guppies.
* Shrimp: They can be a good addition, but watch for the catfish eating them.
Before adding any fish, do thorough research, consult with experienced hobbyists, and observe their behavior carefully. The goal is to create a thriving, balanced community where all fish can thrive.
