The striking Figure Eight Pufferfish ( Canthigaster valentini) is a popular choice for saltwater aquariums, captivating hobbyists with its unique markings and relatively docile nature. However, selecting appropriate tankmates is crucial for its health and wellbeing. This guide delves into the best and worst choices, addressing common questions surrounding compatible fish and invertebrates.
What Size Tank Do Figure Eight Puffers Need?
A minimum tank size of 20 gallons is recommended for a single Figure Eight Puffer. However, larger tanks (30 gallons or more) are highly preferred, especially if you plan to add other inhabitants. Adequate space reduces stress and prevents aggression, ensuring a thriving environment. A larger tank also allows for more complex rock structures and hiding places, enriching the puffer's habitat.
Are Figure Eight Puffers Aggressive?
While generally considered peaceful compared to other puffer species, Figure Eight Puffers can display territorial behavior, particularly towards similarly sized fish that might compete for food or space. Their temperament is also influenced by tank size and the presence of suitable hiding spots. Overcrowding can trigger aggression.
What Fish Can Live with Figure Eight Puffers?
Careful consideration is paramount when selecting tankmates for Figure Eight Puffers. Choose species that are peaceful, unlikely to be perceived as a threat (or food!), and possess different habitat preferences to minimize competition. Here are some suitable options:
- Small, Peaceful Wrasses: Certain wrasses, like the neon goby, can coexist peacefully provided sufficient space and hiding places are available.
- Gobies: Many goby species, particularly those that inhabit the substrate or lower parts of the tank, are good choices. Avoid larger or more aggressive gobies.
- Small Shrimp: Cleaner shrimp can contribute to the tank's overall health and won't pose a threat to the puffer.
- Certain Snails and Hermit Crabs: These invertebrates help with tank maintenance and generally pose no risk to the puffer.
What Fish Should NOT Live with Figure Eight Puffers?
Certain fish should be strictly avoided due to their potential for conflict or becoming prey. These include:
- Larger, Aggressive Fish: Any fish that might see the puffer as food or pose a threat should be excluded.
- Slow-Moving Fish: Puffers are opportunistic feeders and might target slower fish.
- Fish with Long Fins: The puffer's beak could injure fish with flowing fins.
Can Figure Eight Puffers Live with Corals?
This is a tricky question. While generally not aggressive towards corals, Figure Eight Puffers may accidentally damage delicate corals through their exploration and foraging. Their beak can accidentally knock corals over or damage polyps. Sturdier, hardier corals are more likely to survive, but it’s best to avoid delicate corals altogether. Consider the overall tank environment and puffer's personality before introducing corals.
What are the Best Invertebrates for Figure Eight Puffer Tanks?
Invertebrates offer a safer option for tankmates, adding diversity without the risk of aggression or predation. However, always ensure invertebrates are large enough to avoid being eaten. Suitable choices include:
- Certain Snails: Larger snails are less likely to become a meal.
- Hermit Crabs: Choose larger species that can avoid being caught.
- Cleaner Shrimp: These shrimp are beneficial to the tank's overall health and generally not a threat to puffers.
What Size Should My Tank Be for Multiple Figure Eight Puffers?
While possible, keeping multiple Figure Eight Puffers together significantly increases the risk of aggression and territorial disputes. A much larger tank (75 gallons or more), combined with ample hiding places and careful observation, may help mitigate these risks, but it's generally not recommended for beginners.
This guide provides a starting point for selecting appropriate tankmates for your Figure Eight Pufferfish. Remember to always research individual species thoroughly and closely monitor your tank inhabitants for any signs of stress or aggression. Observe their interactions and adjust your setup as needed to ensure the health and wellbeing of all your aquatic companions. A well-planned and spacious aquarium will contribute greatly to a successful and harmonious community tank.
