Choosing Saltwater Tank Mates
Choosing the right tank mates is key to a peaceful saltwater aquarium. Fish and invertebrates must live well together.
Understanding what makes species compatible helps you create a thriving marine environment.
Factors Influencing Compatibility
Compatibility depends on size, diet, and aggression levels. Some fish may bully or eat others.
- Size difference – bigger fish may harm smaller ones
- Diet – carnivores might attack herbivores
- Territorial behavior – some species need their own space
- Activity level – fast swimmers may stress slow species
Behavioral Traits To Consider
Look at how fish act around others. Peaceful species prefer calm neighbors.
| Trait | Effect on Compatibility |
| Territorial | May chase or fight other fish |
| Schooling | Needs groups to feel safe |
| Shy | Can be stressed by active tank mates |
| Aggressive | Can bully or harm others |
Environmental Needs
Different species need specific water conditions and tank setups. Match these needs carefully.
| Species | Water Temp (°F) | pH Range | Habitat |
|---|---|---|---|
| Clownfish | 74-78 | 8.1-8.4 | Reef |
| Blue Tang | 72-78 | 8.0-8.4 | Reef |
| Mandarinfish | 72-78 | 8.1-8.4 | Sand/Coral |
| Cleaner Shrimp | 72-78 | 8.0-8.4 | Coral |
