The lifespan pf many of the more popular fish we commonly keep in the hobby can surprise many people. Clownfish for example can commonly live up 15 years in captivity and many tangs can live up to 25 years.

One of the biggest lessons that I had to learn the hard way was to take my time when picking out a new marine fish at the local pet store. It can be very easy to get caught up in the excitement of finally finding the fish that you have been looking for, but you should really look before you leap. You want to carefully observe the fish to make sure it is not showing any potential signs of sickness. At times, this can be hard to do if the fish is stressed, but some of the signs to look for are:
I will typically observe the fish in the store for about 30 minutes. Sometimes I will repeat this process over two or more different days until I am satisfied there are no visible symptoms and the fish appears healthy. In case you own many pets, you can learn here more information on how to use CBD products to keep hem healthy and happy.
Once you have had a chance to observe the fish and have not noticed anything odd, I would also suggest that you request the store to feed the fish so you can see it eat . I would never purchase a fish that was not eating as that can sometime be a indication of internal problems.
And, as always, I strongly recommend placing you new fish in a properly set-up quarantine tank for careful observation. There are so many other disease your new fish could be infected with that will take a very long time before there are any noticeable external symptoms.

Testing your water
Many of the fish and corals that we keep in our aquariums can be more sensitive to water conditions when compared with most fresh water fish. This is even more critical in smaller set-ups as problems with water quality can get very bad very fast. You need to be testing the basic parameters in the beginning while your tank matures. Once you get a lot of coralline developing and you have started adding more fish and/or corals which consuming many elements from the water, you will need to slightly expand this to include other elements.
Without testing your water quality at least weekly, you will not be able to determine how well your set-up is maturing or much much elements the system is consuming from the water.
The below link will allow you to better understand what I am talking about
I’m the type of hobbyist that likes to keep things as simple as possible while maintaining the best possible water quality that I can. One of the more important parts of this is completing weekly water changes. I have found that completing a weekly water change of about 10% to 20% works well for maintaining trace element that will be consumed by corals and coralline algae while helping to prevent a buildup of nitrates and/or phosphates in the water. Depending on the amount and type of corals combined with the bioload of your fish, you can adjust the amount of your water change to have the same effect. I have found the less supplements you have to dose, the more stable your water will be. Weekly water changes allow me to achieve that without having to put a lot of effort and expense into dosing and testing trace elements.

Some people have asked me which substrate is best for their set-up. Below are some random thought on the subject that always come up in these conversations
1 – Why do you even need substrate ? You can go “bare bottom” saving yourself some money and a little extra work. Pros: less work, less expense. Cons: waiting for coralline to grow on the bottom, doesn’t look as natural as you can have with substrate
2- What are you planning to stock? If you are planning jaw fish or some of the sand sifting fish, then you need to have a substrate that meets the specific needs of those fish.
3 – What about Live Sand. In my experience, it is not worth the extra expense. As this product is placed in a sealed bag and potentially exposed to temperature extremes, you will get a very large die-off of the beneficial bacteria’s that will be there.
4 – What type of flow are you planning for your set-up. If you are planning a high flow set-up, then stay away from finer particle sand. The flow within the tank can move the substrate around if you are not careful
5 – Stay away from crushed coral or excessively large particle substrates. It is very easy to have debris collect in the cracks and crevasses in these types of substrate were your cleanup crew cannot get to it. Without a lot of extra substrate cleaning, this will lead to higher than normal nutrient levels over time.
6 – Do not use substrates meant for fresh water aquariums. These fresh water substrates (especially sand) will contain higher amounts of silicates than what is normally found in marine substrates. This will put higher levels of silicates in your water which in most cases will lead to a lot more diatoms and other algaes in your tank.

Many hobbyist just entering the hobby will have “sticker shock” when they see the prices for good quality live rock. Sometimes this will result in some people t trying to find the cheapest approach to filtration. This is the wrong approach to take. Cutting corners on your filtration will always result in long term difficulties. The below links can better explain what I mean
This is one lesson I had to learn the hard way many years ago. It can be very easy to get a fish that is carrying, or infected with, a disease in the very early stages making it very difficult (if not impossible) to visually see. I used to lose many fish to ick before I started using a quarantine tank. Many people skip this process and add new fish to their display tanks right away, using the agreement that quarantine new fish is too much work and expense. In my experience, the work and expense of dealing any type of disease in your main tank is just as costly and just as much effort as utilizing a quarantine set-up, however, it can prevent the loss of existing fish in your display tank.

When looking at getting LED lighting for your aquarium, it can seam overwhelming when considering all the features and options that you will have to choose from. However, it doesn’t have to be all that difficult if you keep it simple. I have learned that applying a few simple concepts, or rules of thumb, LED lighting become a whole lot easier to understand. The below is what I have learned. This is not and all inclusive set of instructions, just something simple to get you started if you have no experience with LED lighting. Most people do not pay attention to the angle of the lenses used or do not understand how different the wattage can be with a LED diode (as compared to a T5 or T8 bulb) and they end up with a fixture that really will not meet their long term needs.
I have included some simple guidelines for both fresh water and marine environments so you may also have a few other points of comparison.

One of the growing trends that I have seen (and experienced) is that flukes are becoming more and more common in the hobby. It used to be that fluke were more common on only certain types of fish, but more and more it seems that all fish can easily get them, or at least that has been my experience.
Flukes are a type of parasite with the broad group of gyrodactylus parasites. There are two common types of flukes, the ones that infect the skin of the fish (dactylogyrus trematodes), and the second that will infect both the skin and gills of the fish (monogenenean trematodes). Both can be very hard (if not almost impossible) to visually see on the fish until very advanced stages. While attached to the fish, they will feed on the tissues they are attached to. At some point they will start releasing eggs which will fall and lay dormant within the aquarium for about a week. They will hatch , releasing a free floating / swimming larva. This larva will survive for two or three days without attaching to a host before dieing. Typically the larvae will attach itself to either the gills or skin of the fish. Once attached, the larva will develop into a worm and releasing eggs continuing the life cycle. This final stage can last for about a week, maybe a little longer
Common Symptoms to look for:
The below list is the most common symptoms that you will find. You may notice one or many of the symptoms listed below:
1 Cloudy eyes
2 Rapid breathing
3 Fraid fins
4 Excessive slim coat production
5 Loss of appetite or even completely stopping to eat
6 twitching/shaking the head from side to side almost like it was trying to shake something off its head
7 discolored blotches on the fish which can even look a lot like velvet some times
8 Flashing against objects in the aquarium with periods of almost no activity
9 White to almost translucent spots on the fish that look almost like the ick virus, but are larger and not as close together.
1- Fresh water dips
While many hobbyists still successfully use freshwater dips, I do not like nor do I recommend fresh water dips. When completed incorrectly, they can cause more harm than good to an already sick fish. Additionally, with many of the new(er) medications available today that are a lot more effective and less harmful and less stressful to the fish, I feel fresh water dips are no longer required.
2- Treatment with medication in a QT set-up
This is my preferred method and is the one that I have obtained the most success with. I would recommend a treatment with Prazi-pro. This medication is safe to use in reef tanks with SPS corals and carpet anemones, and is also safe to be used in a QT set-up with copper based medications. However, they key to being able to successfully treating flukes is catching the symptoms early enough for the treatment to work. If the infection has spread to much through the gills, or the fish is no longer eating, you have a lower chance of successfully treating the fish. You also have to keep in mind, is that by treating a infected fish in a QT step-up or in a medicated treatment dip, you are not dealing with any of the parasite’s eggs that could be in your main tank waiting to hatch and infect / re-enfect your fish. You may have to consider treating your whole system.
The only caution to using prazi-pro in a display tank is that it will have an effect on worms (like flat worms) as well as some of the more sensitive filter feeders like coco-worms.
I always QT any fish I get before adding them to my display tank. As fish can carry flukes without actually becoming infected, I always use a preventative treatment of prazi-pro while in QT. While there are many medications out there that work on flukes, I have found prazi-pro works the best and it has the least side effects. Copper based medications will not work on flukes.
How did flukes get into my aquarium?
In short, they will have to be brought into your set-up by you. Typically they will get into your setup through:
1 An infected fish
2 On live rock from a infected set-up
3 On a coral form a infected set-up
4 In water added to your tank from an infected set-up
Poor water quality and / or environment stress will allow fluke to thrive and really take hold in your set-up.
Just a Word on Using Medications
1 Make sure your salinity is at least at 1.025 when using meds. All meds have a stronger than intended impact when used at lower levels of salinity
2 If treating with Praz-pro, remove your skimmer cup but leave the skimmer running. The use of praz-pro will make your skimmer go nuts. It will produce a truly amazing amount of bubbles like you have never seen before. You want to still have your skimmer running to keep the oxygen levels high in the water as some medications like praz-pro can lower the amount of oxygen in the water which is something you want to avoid.
3 Don’t forget to remove any type of carbon that you have running in your system
4 Fresh water dips will only remove the flukes from a infected fish, and not the flukes which are laying dormant within your set-up
5 Poor water quality and environmental stress will make most medications close to being useless
