Frequently asked questions
At Havoc Reef Marine Fish and Coral, we understand that starting or maintaining a marine aquarium can bring up many questions. We've compiled some of the most common queries to help you on your aquatic journey.
Which marine fish are best for beginners?
Hardy and peaceful fish like Ocellaris Clownfish, Damselfish, and certain Gobies are often recommended for beginners due to their adaptability.
How many fish can I keep in my marine aquarium?
This depends on your tank size and filtration system. A general rule is 1 inch of fish per 5 gallons of water, but research specific species requirements.
Can different species of marine fish live together?
Compatibility is key. Research each species' temperament and habitat needs before introducing them to your tank to avoid aggression and stress.
How do I acclimate new fish to my tank?
Use the drip acclimation method to slowly introduce your new fish to your tank's water parameters. This minimises stress and shock.
Why are my fish not eating?
This could be due to stress, poor water quality, illness, or simply a new environment. Check water parameters and observe behaviour closely.
How long should I quarantine new fish?
It is highly recommended to quarantine new fish for at least 4-6 weeks to prevent the spread of diseases to your main display tank.
Which fish are reef-safe?
Many fish are reef-safe, meaning they will not harm corals or invertebrates. Examples include most Gobies, Blennies, and Clownfish. Always verify compatibility.
What size tank do I need for a particular fish?
Tank size requirements vary greatly by species. Always research the adult size and activity level of the fish you wish to keep.
How often should I feed my marine fish?
Most marine fish benefit from small feedings 1-3 times a day, only offering as much as they can consume within a few minutes.
Why is my fish hiding or behaving differently?
Changes in behaviour can indicate stress, illness, or environmental issues. Check water parameters, look for signs of disease, and observe for aggression.
Which corals are easiest for beginners?
Soft corals like Zoanthids, Mushrooms, and Leather Corals are generally more forgiving and easier for beginners to care for.
What lighting do corals need?
Corals require specific lighting spectrums and intensities for photosynthesis. The type and amount depend on the coral species. LED and T5 lights are popular choices.
How quickly do corals grow?
Growth rates vary significantly by coral species. Some soft corals grow quickly, while many stony corals grow very slowly.
How do I acclimate new corals?
Acclimate corals using a slow drip method or by floating them in your tank to match temperature, then slowly introduce them to your tank's lighting.
Where should I place different corals in my tank?
Placement depends on light, flow, and aggression. Ensure adequate space between corals and place them according to their specific needs.
How do I know if my coral is healthy?
Healthy corals will typically have good colouration, extend their polyps, and show no signs of recession or tissue loss.
Why are my corals losing colour or not opening?
This can be a sign of stress from inadequate lighting, poor water quality, incorrect flow, or pests. Check your tank's parameters immediately.
How often should I feed corals?
Some corals primarily rely on photosynthesis, while others benefit from target feeding with liquid or particulate coral foods a few times a week.
Can different corals be kept together?
Yes, but be aware of chemical warfare and stinging. Provide adequate spacing and research compatibility for best results.
What water parameters do corals need?
Corals thrive in stable parameters: salinity (1.024-1.026), alkalinity (7-12 dKH), calcium (400-450 ppm), and magnesium (1250-1350 ppm).
How much does it cost to set up a marine aquarium?
Initial setup costs can vary significantly, from a few hundred pounds for a small nano tank to thousands for larger, more advanced setups.
What size tank should I start with?
Many recommend starting with a larger tank (50 gallons or more) as it provides more stability, although smaller tanks can also be successful with diligent care.
What equipment do I need for a marine tank?
Essential equipment includes a tank, filtration (skimmer, live rock), lighting, heater, powerheads for flow, and a reliable test kit.
Do I need a sump?
A sump is highly beneficial for housing equipment, increasing water volume, and enhancing stability, but it is not strictly necessary for all setups.
What type of filter should I use?
Live rock and a protein skimmer are fundamental biological and mechanical filtration methods. Additional filters like refugiums can also be beneficial.
What are your delivery options for live fish?
We offer live fish deliveries twice a week. The cost is £25 per box. Please ensure someone is available to receive the delivery.
