Saltwater Aquarium Advice

Seeing as my marine aquarium passion is based on the marine life itself, I thought it was time I started to do some posts on popular marine pets!

The Clownfish has got to be the most popular marine aquarium inhabitant worldwide, mostly thanks to the Disney movie “Finding Nemo”.  Other than this they are cute and pretty easy to care for and require little space. The Clownfish is a type of Damselfish, they are very colorful with coloring that ranges from yellow,maroon and even black to shades of orange. The most common coloration found is a bright orange intermingled with white stripes or patches (such as Nemo!).

Clownfish and anemonefish are from the subfamily Amphiprioninae in the family Pomacentridae. There are about twenty eight species in total, one in the genus Premnas while the remaining are in the genus Amphiprion. They are native to the Indian and Pacific oceans.

The one thing that characterises all species is the symbiotic relationship they have with their host anemones. It is currently thought than when these fish are embryos lying on the reef surface, they become “addicted” to the scent of a particular anemone then when they hatch they go to settle in that anemone and spend their entire lives defending it from other fish and are always close to it, retreating inside the deadly (to other fish!) tentacles when danger lurks.

It is thought that the Clownfish are resistant to the Anemones stinging cells because of the mucus their bodies secrete, another theory is resistance to the potent poison has come from many years of co-evolution with the Anemone’s. The Clownfish chase off would-be anemone-munchers, feed off undigested food particles and dead tentacles which otherwise could rot and damage the invertebrate and fertilise the anemone with their droppings. In return the anemone provides life-long shelter and protection. The Clownfish generally forms a partnership with the anemone species Heteractis magnifica, Stichodactyla gigantean and S. mertensii.

Another little known Clownfish fact is that they are all born as males and can change sex if required in their social group. The social group consists of 1 breeding pair and immature or non sexually active males. If something happens to the breeding female the dominant male will change sex and replace her!

The hardy Clownfish require little space in the aquarium environment, if their host anemone is present they may rarely venture more than a few inches from it for their entire lives (which can be for a number of years). If their preferred host species is not available Clownfish will commonly settle in soft corals or large polyped stony corals, the problem with this is that the coral may sometimes die and the Clownfishs’ skin may become irritated by the coral as the clownfish is constantly swimming around its host.

The Clownfish is one of the first marine fish to be successfully captive bred, which is awesome as it takes pressure of the reef environment to constantly supply Clownfish to home aquarists. You should always seek out captive bred Clownfish for this reason, additionally captive bred fish are a lot less stressed out, are used to humans and aquarium food and are more resistant to disease. Clownfish are social creatures and are best kept in pairs although a few species (like the Maroon Clownfish for example) can be aggressive to each other. They should be kept in aquariums 40 litres or more.

Basically Clownfish are hardy, fun and interesting fish to keep and will require minimal effort from their owners. If you can get a host anemone for them as they will be most happy, although these anemones can be hard to care for. Clownfish are peaceful but can be territorial (especially with their hosts) I advise you not to mix species as this can lead to a lot of fights.

Hi guys, todays post is a pretty important topic, how you can avoid making a few of the most common mistakes with your marine aquarium.

This mistake-making epidemic we see in the hobby today basically stems from people falling in love with the idea of having an awesome marine aquarium and rushing in head-first without doing their due dilligence first. This is the main reason I decided to write “Ultimate Secrets To Saltwater Aquarium Fish and Invertebrates” to educate people because the pain that comes from watching your beloved marine pets dying is immense and most times it really is preventable.

So lets get started;

1. Buying marine life without knowing enough about the specimen:

This is probably one of the most preventable mistakes you can make. So many people contact me upset about their newest pet dying then you find out its because they had no idea how to care for and feed it, and sometimes they dont even know what it is. Dont be pulled in by the pretty colours or the nice shapes of marine life at the pet shop, any purchase you make should be fully researched FIRST! And dont just rely on the person at the pet shop, do your own research and ensure you know what the exact requirements are for keeping your new pet in optimal health. You also need to ensure (as ive said time and time again!) it will be compatible with your marine aquarium set up and the current marine pets you have.

2. Not taking enough time:

In todays society everything is moving so fast, the opposite is true with your saltwater aquarium. You need patience people, if you move too fast things go wrong and this can be both expensive and heart-breaking. You really need to take the time to study up on marine aquarium keeping first, before you begin and take things slowly and carefully. Every step must be carefully planned out and executed. Too many people have contacted me with their problems which are a direct result of doing things too fast.

3. Marine life compatibility:

A very common cause of trouble; you really need to research the behaviour of your new pet and check it will be suitable with what you already have. For example predatory fish and timid little herbivorous school fish often do not mix! The ocean eco-system is ruled by a complex series of marine life interactions, therefore you cant predict what will happen, you MUST do your research before you buy.

4. Marine aquarium overload:

This is when you put too much marine life or live rock/sand into your aquarium at once (remember common mistake number 1?) the system cannot handle it and the delicate balance is thrown out and new tank syndrome often results. This problem can be much worse when the new tank is not fully cycled. The solution? Slow down, move slowly and gradually add more stock so the system can cope much more efficiently.

5. Lack of tank maintenance:

To ensure your aquarium remains a pristine environment for your marine life you MUST conduct maintenance at regular intervals. if you do this you should seldom have water quality, high nitrate, excessive algae or contamination issues. You need to be strict with yourself on this, it is a key area for preventing problems with your marine aquarium. A little work now will save a lot of problems in the future.

6. Using poor quality water:

A lot of people use tap water or other unpurified water to make up saltwater for the aquarium, this can often be a pretty bad idea as it can lead to water quality issues which can sometimes be pretty dramatic (like all you fish dying!). I recommend you purchase quality distilled or RO water, or some form of pre-purified sea water. Failing that another option is to use a water purification filter, however make sure it is a quality product. Using good quality water is a wise investment that will greatly help prevent water problems.

7. Unwittingly purchasing sick marine creatures:

The key to not making this mistake is to observe the fish for a while (see my other blog post about selecting marine life for more info), studying their behaviour and the fish themselves carefully. You should learn what common tell tales signs of disease and illness to look for. Another major indicator of sickness is when the fish get fed, if its not eating normally then do not buy it! Discovering whether a fish is healthy or not is very easy to do and will save you a lot of trouble.

8. Diagnosing disease incorrectly:

You need to learn to recognise the signs of common diseases and parasite infections accurately, then you will not go through the tedium of treating one disease while your marine life gets sicker from another. For example saltwater ich is commonly mistaken for white spot (and vica versa) these have similar symptoms but are caused by different disease organisms that require very different treatments.

9. Poor water circulation and filtration:

These two factors are a must for any healthy saltwater aquarium. If there is not enough biological filtration the water can easily build up to toxic levels that can kill marine life. A lack of adequate water circulation leads to a build up of algae, low dissolved oxygen and sessile marine life such as corals not getting enough food. The good news it that you cannot really have too much filtration or water circulation (within reason), however there are a wide range of choices in purchasing these two essential systems, especially filtration; where not getting the right filter set up for your waste levels can lead to problems. Circulation can be easily improved by adding additional powerheads or a surge device.

Compatability issues within marine aquariums are the number one thing first time aquarists over look. This can easily lead to an expensive, heart breaking disaster in your tank.

So many times I have had to tell people things like; ”You cant put that with that” and “you should take that back to the shop because it will eat your other fish”.

Basically, people just need to realise that all fish are not neccessarily compatable with each other due to the various roles each of them play in the ocean ecosystem. One of the most important factors in considering which fish to put together is considering who’s a herbavore and who’s a carnivore. Fishes eating habits can dictate their behaviour to some degree. For example a carnivorous fish may exhibit predatory behaviour toward herbavorous fish that may have made up part of their diets in the wild. A general rule of thumb is try to put like species together (i.e mostly herbavores etc); groups that co-exist in nature, this will lead to harmony in your marine aquarium.

Other factors that require careful consideration are the degree of territorial behaviour a species exhibits. Beware of fish species that are highly territorial when you want a peaceful fish community. Many types of fish should only be kept as individuals as when there is two or more there can be a lot of aggressive behaviour.

Another thing to consider is behavioural types, and trying to match these to the ideal type of aquarium you want. For example some fish species are very shy and timid, they can get easily stressed when put with active, boisterous fish species.

I cant stress enough that people really need to do a lot of research into the fish they want and how that fish will get on in the wider aquarium community. Basically if you do your homework you most probably wont get a nasty surprise.

My book “Utimate Secrets to Saltwater Aqaurium Fish and Invertebrates” from www.saltwater-aquarium-advice.com has detailed fact sheets about the 16 most popular species of marine fish kept in saltwater aquariums. This section has comprehensive fish compatibility information, because the issue of compatibility is really so important to any marine aquarium
