Aquaman's Coral Cave's guides to success!

Starting your fish aquarium journey!

Hey! My name is David and I want to teach you how to start your or your family's fish hobby.  If your looking to start your first aquarium then follow these easy steps in purchasing equipment, setting up your aquarium, and maintaining it in your home. Please keep in mind that every aquarium is different and some may finish faster or take longer than others.

Firstly, you'll need to purchase your equipment! This can be one of the more challenging steps because there are many question to be answered before the first purchase like: "How much room do we have to work with?" That question can narrow down how big of an aquarium you could potentially purchase. Next you'll want to decide what you would like to house inside the aquarium. This information will let you know how big of an enclosure your livestock will need at adult or full size and also let you know what type of substrate and decor you will need for those animals. So now that you know how big of an aquarium you need and what your home will allow. Once you decide, you can look at the standard sizes and follow up with measurements to make sure that it will accommodate your space. If you do not wish to have a standard cut tank then you could have one custom made. (further info given at store) 

Also think about your filtration. A sump system will require a drilled tank or a "hang on back" overflow box while and canister filter or a regular HOB filter will not require any drilled holes in the glass aquarium. All of which should be able to be stored under your tank stand, set out of the way. 

5 Tips when setting up:

Equipment guide and setup

Now that you know what size aquarium you want, it's time to get your equipment. Buying new is great because you know it "should be" reliable being new. That being said second hand or gently worn systems make for a great budget start up. You could even look out for deals and piece together your own system over time. Either way we will need to collect these items for your aquarium to work. 

Needed equipment: Tank, stand, substrate, decor, filter/sump system, heater, thermometer, conditioned water, and light 

Extra recommended equipment: 2-5 gallon buckets, towel, power strip, net, gravel vacuum, glass scraper, water test kit.

Once you have your equipment ready its time to assemble your aquarium. Mark on the floor with tape to accurately place your tank stand. Place your aquarium on top and then fill the bottom of your aquarium with appropriate substrate. (pre-rinsed unless directed not to) If you are planning on planting the aquarium, use a planting substrate then put your desired substrate on top. The layers will allow the plant roots to grow underneath and the appropriate substrate will be left on top. Then fill your aquarium with conditioned water 2/3 of the way up. (use a plate or bowl on the bottom of the tank to not push around the substrate you just laid). At this point stop to decorate your aquarium. It's much easier to decorate once the tank has water inside but we need to leave room for water displacement. Finish filling your aquarium with the conditioned water then start your filtration up. Wipe down any spilled water then install your heater at 78 degrees F. Place your thermometer on one of the sides of the tank. Once the tank has reached 78 degrees, add any beneficial bacteria to the aquarium if you please.(This is not the same thing as water conditioner.) Leave the light off until the Nitrogen cycle is finished. Wait.. What is the Nitrogen cycle? We shouldn't get fish yet?


The Nitrogen Cycle

This part of the page is so important for all new hobbyiest to learn what is  actually happening in your aquarium water. In short, you need bacteria to break down waste that your fish and its food will produce. Getting ammonia in the tank is the first step. Ammonia is found in animal urine and decaying waste. Your animal and its waste will produce this Ammonia and if there is no bacteria present the uncycled water will harm the fish. There is no need  to put any livestock through this cycle as it can kill. This also includes plants. It can harm some and others will use the ammonia to grow and hinder the cycling process! Please wait on plants until the cycle is complete. You can purchase and add ammonia that is made to start the cycle in an aquarium. Many people instead put in a piece of food such as a raw store bought shrimp in the tank for a few days letting it decay and produce the ammonia spike. This is where your testing kit will come into play or you can bring a 2oz water sample to the LFS to be tested. Once you have your ammonia spike you have successfully started the Nitrogen cycle. You may get white cloudy or dingy water. That is known as a bacterial bloom and is good since we want our bacteria to grow in numbers. don't do anything.  Now comes the hardest part. Being patient. You'll then wait for your cycle to finish. "Well when am I finished?" Your Nitrogen cycle is finished when your ammonia and nitrites have both spiked then declined and are now at 0ppm. Once your nitrates are showing a tad then your finished. In some cases it may not show at all. This process can take up to 30 days to finish. Sometimes shorter, sometimes longer. At this point it is safe to slowly start adding in livestock. 

Feeding tip:

I use the rule of 5 minutes. That means feed the fish only what they can consume in 5 minutes. So, if you feed your fish and you notice the is still food in the tank after 5 minutes the make a note for next time to feed a little less. If 2 minutes has went by and all the food is gone, then feel free to feed a little more. Alternate types of foods for better fish health.

Quarantine tank:

A QT is a smaller tank that you put your new livestock in to observe for a few weeks before adding them to your main display. Most fish are caught from the wild. Many of them could carry parasites or disease. After your investment into the hobby I would recommend you do not risk adding a fish that could potentially infect and kill your other fish. instead set up a little tank to observe then for a bit then confidently release them into your main display. 

Stocking your aquarium

Here I want to discuss how to add livestock to your aquarium. Your aquarium's bacteria has grown significantly, but its not at its stongest yet. When we add our first fish, we want to add no more than 6 fish at a time. 3-4 at a time is prefered. After a week, our bacteria will grow yet again to accommodate the influx of ammonia. Do not over feed when adding new fish. Antisipate there being a slight ammonia spike; over feeding will make it worse. Wait a full week then test the water again. If levels are good then I would again make a few more additions to my aquarium weekly. If the levels are still showing some ammonia or nitrite above 0ppm then I would recommend waiting a second week. The tank water may turn cloudy white again, that is the bacteria blooming again to break down the ammonia and grow in numbers to keep up with the new fish. 

When adding a new fish to your tank, rinse off the fish's bag then float it on the top of the aquarium water to acclimate to the same tank's tempeture. After 30 minutes, the fish should be ready to add to your aquarium. I would reccomend straining the fish into a net over a bucket or sink, then transfering them to the tank, attempting not to cross contaminate the shop water with your tank water. 

Many fish are transported all over the world sometimes for weeks at a time. they are frightened and weak. They may not come "out and swim around" immediatly. Please give them space to learn their new habbitat. 

After some time algae will start to form in the aquarium. That is the time for your clean up crew or "Algae eaters". Waiting for algae means they will have enough food to eat with out you haveing to supply them with algae rich food. 

Maintenance on your aquarium!

You'll have to do some maintenance for your aquarium. Your light will grow algae in your tank and even though you may have some "clean up crew" you will have to manually clean the dust algae off the glass. Either with a scraper or a pad of some sort. Also your filter will become full/dirty after some time. I recommend changing the tanks filter and carbon(charcoal) once a month at least. Twice a month if you budget and time allows. Also I recommend that after the tank has cycled and has been running for 90 days to start doing 10% water change weekly or biweekly. The aquarium will also evaporate, just like a puddle outside. You will have to keep it full with properly conditioned water so that the tank will remain stable. Filling the tank back up with water from evaporation is not a water change! Water change should only happen once the tank is at its top proper filled level. Clean the outside glass from streaks and fingerprints only with water. Refrain from using chemicals to clean anything to do with your aquarium. A gravel vacuum is recommended once a month. This can also take the place of one of your water changes. The vacuum will pull uneaten food and detritus out of your aquarium and reduce the nitrates that are in the aquarium. 

FAQ or frequently asked questions:

What do they eat?

Your fish will enjoy an array of food including dry flakes, pellets, flash frozen live foods, frozen food medley and insects! Each fish will enjoy certain type of food so it is best to alternate different foods. Also alternate foods will establish better nutritional health!

What do I do when I go out of town for the weekend?

In my opinion, nothing. Keep the light on a timer for regular times (8 hours max) or just keep the light off. the tank will be fine without light for 3-4 days. Also the fish can forage through an established tank and be fine for 3-4 days without the daily feeding. I do not recommend an automatic feeders as they are known to fail. Either falling in the tank or distributing too little or too much food. A weekend feeder block can work but may muck up the water. Its best to just let them go or teach the neighbor what to do.

Can I put any rock in the aquarium?

I would be cautious as to what rocks you put in your aquarium. Some rocks will release minerals into your water making it more alkaline. Some fish prefer that and some do not. I would recommend that you choose a rock that will not change any water parameters unless actually desired. 

Can I put a fish in a tank less than 5 gallons?

When someone asks me this question, I like to think of the quote from the original Jurassic Park movie when Dr. Malcolm says "They were too busy wondering if they could, instead of thinking if they should". Yes your COULD keep a fish alive for a time in something so small but should you? When these fish are captured out of the wild they have enormous spaces to venture around and being confined to such small parameters will ultimately lead to stress on your animal. Similar to a dog chained to a tree, this does the fish your keeping no justice for its existence and it should be no wonder when the fish "acts funny", "doesn't swim much" or "doesn't have much color". Save up and upgrade as soon as possible. At least to a 10 gallon aquarium. 

Why is my water turning green?

Answer: Too much light! Light grows algae. No light, no algae growth. Either from the aquarium light on too long (recommended 8 hours max), natural light from a window, or just house lights on in the same room. 

Why does my water look cloudy white or dingy?

That is a bacterial bloom, your bacteria is growing in ranks because of an increase in ammonia or nitrite. DO NOT try to use a product to clear it up or do a water change. Ride it out an let your bacteria form. it will go back clear once levels have stabilized. 

How do I start a Saltwater tank?

Just as I have stated above. The conditioned water should be RODI water and should be mixed with marine salt per recommended ratio and tested at 1.026 specific gravity. Also I am not going to recommend a HOB filter, even though "you could do it". I won't last long as the salt will ware on it harder. The sump system or a canister filter is your best bet for filtration. 

How many fish can I put in there?

So this can be a loaded question. In fresh water we say about 1" of fish = 1 gallon of water. So 10 - 1" long fish in a 10 gallon aquarium. But if a fish is 10" long it doesn't belong in a 10 gallon aquarium. Obviously that would need a much larger habitat. Also take into account that most fish are going to grow so a 1" fish this year can easily be a 3" fish next year. Please do your research when looking to stock BEFORE you purchase your fish that its max size will work with your tank and other tank mates. 

Are they going to fight my other fish?

This a common question we get at the shop. In the aquarium hobby, someone seeking to keep livestock should be trying to learn all they can about the animal they would like to keep. As talked about above that includes Aquarium space minimums and types of decor and substrate that is proper for that fish or livestock. Tank mates are no exception. Knowing where your fish comes from and what other fish it tends to cohabitate with is the hobbyist's responsibility. 10 minutes of smartphone research will answer any of your questions about your fish and probably teach a few other things that will help you later on about fish aggression. 

MY FISH IS SICK! WHAT DO I DO!?

Research. The first step in any medical treatment is identifying the underlying cause of the problem to eliminate and treat it. Again 10 minutes of research will help tons. Once the disease, fungus, infection or parasite is identified correctly then you can seek the proper treatment. There are a number of treatments found at your local LFS.
