In a frag tank, which is specifically designed for coral propagation,
choosing fish and invertebrates that are compatible with the delicate nature of coral growth is essential. Here are some preferred options for a successful frag tank:
Preferred Fish:
- Clownfish: Clownfish are a popular choice for frag tanks due to their relatively small size and peaceful demeanor. They won't disturb corals, and their presence adds a lively dynamic to the tank.
- Goby Species: Many goby species, such as the watchman goby or clown goby, are suitable for frag tanks. They are small, peaceful, and often form symbiotic relationships with pistol shrimp, creating an interesting and beneficial dynamic.
- Royal Gramma Basslet: Known for their vibrant colors and peaceful nature, royal gramma basslets are a great addition. They typically stay close to rock formations, making them less likely to interfere with coral placements.
- Firefish : Firefish are slender and peaceful, making them suitable for frag tanks. They add a vertical dimension to the tank as they hover around rock structures.
Preferred Invertebrates:
- Cleaner Shrimp: Cleaner shrimp, such as the Scarlet Skunk Cleaner Shrimp, not only add visual interest but also serve a functional role by helping to control parasites on fish and corals.
- Hermit Crabs: Hermit crabs can be useful in a frag tank to help control algae and detritus. However, it's crucial to provide ample empty shells for them to move into as they grow.
- Snails: Various snail species, like Nassarius and Cerith snails, contribute to algae control and detritus removal. They are generally small and won't disturb corals.
- Sea Cucumbers: Some reef-safe sea cucumber species can aid in sand bed maintenance by processing detritus. It's essential to research and choose species carefully to avoid any potential issues.
Remember, when selecting fish and invertebrates for a frag tank, compatibility with coral growth is key. Avoid aggressive or large species that may damage or disturb the corals. Additionally, maintaining stable water parameters and providing appropriate hiding places for the inhabitants will contribute to a thriving and harmonious frag tank ecosystem.
