Category:Fish Difficulty - Moderate
From The Aquarium Wiki
This is list of aquatic animals that are moderate to keep in an cycled aquarium tank. The animals listed here are relatively hardy, but may have some requirements that means they either will not tolerate flucuations in their tank environment, need careful consideration with tankmates or need specific foods.
These would be best kept by those with some experience in fishkeeping, or by beginners after extensive research.
