As we have discussed in the earlier entry on Nano aquarium (or small-size aquarium), some of the tips to help you achieve the desired results are here: -
1. CHOOSE YOUR KIT -
A hobbyist’s should play very safe by opting for a foolproof aquarium kit. Choose a kit that offers a built-in lighting and an integral filter system. Thus you are ensuring that all the required components are at their assigned place .The only additional item you need is a proper heater. The most customary and traditional 12-gallon aquarium kits are provided with the classic Eclipse System Twelve or the cutting edge Nano Cube. Both are priced around $100 and offer trendy bow front designs with panoramic viewing.
2. POSITIONING -
Though nano sized of 12 gallons, when filled up it weighs 120 lbs! You must resist that temptation of keeping this heavy mass on your desktop or even on your office cabinet. Well-designed and decorative stands to hold so much of weight are readily available. It is worth investing in a proper stand and keep tension at bay. In the bargain you may get extra space for storage.
3. SELECT YOUR THEME –
A heterogeneous combination of species, which may give an unaesthetic look, it is advisable to decide on a theme and confine your collection around that. You could concentrate on a particular species, a region or even a community grouping. Apart from giving a balanced and homogeneous neat look, it becomes easier for you to keep water parameters under control for all the inhabitants have similar needs. Not only that, the informal surroundings like housing and breeding arrangements that you provide will keep stress levels to a low scale.
4. REMEMBER 3S’s-
Stock Small & Sparse – You must practice restrain and be patient when experimenting with a small aquarium .You should refrain from overpopulating your aquarium, else it ill become too cumbersome for you to maintain quality of water. While instituting a new system, bring in only a few fish at a time. Have patience and observe a long gap of a couple of weeks, maybe a month or two before making any additions. At the initial stages you must restrict your choice to as small fish as possible. You take on from there and continue to build gradually. As a starter opt for just one or two showcase fish, coupled with a few of bottom cleaners.
5. PRACTICE NATURAL FILTRATION –
As can be expected fish will grow healthier if the surroundings you provide are close to being natural. Employ nature to work for your aquarium’s health. Artificial configurations in the form of plants or rocks make it necessary to employ extra means for filtering of water. Think in terms of natural plants and eco-friendly gravel for freshwater aquariums, and live rock or sand for your nano reef.
6. TO BRIGHTEN IT -
As a new entrant to the field perhaps you would like to have a closer watch on the growth of plant or reef in your aquarium. Improved hood lighting by incorporating a higher wattage gives the desired results. It’s very convenient. Tailored retrofit kits specially designed for the purpose are easily available and can be fixed in no time.
7. DAILY EXERCISE –
A limitation with Nano Aquariums” is the frequent changes occurring in water quality, thus making it mandatory to check and test it everyday. Spare time to observe behavioral patterns of fish. Watch how they gasp and where do they hide or drift or scurry to. Continued watching of their behavior will help you to diagnose their overall health. Eventually you will be able to make out when they are unwell. Also stock some 5-in-1 Quick Dip Strips close to your aquarium for “ballpark” parameter checks. Any changed level of nitrates, or pH level should be of concern to you. Employ pro-grade test kits to arrive at a definite conclusion and take remedial steps.
8. WATER CHANGES, FREQUENT BUT PARTIAL
Natural phenomenon like rain and water currents continue to keep refreshing and recharging water as toxins get diluted and carried away before those reach harmful levels. To keep your stock in good health you simply keep altering 10-20% of its water content as frequently as about twice a week. This becomes all the more important when you have a larger population of fish or feed them with superior bio-loads.
9. MEDIA CHANGE
To keep away from the curse of algae for better health of your fish and offer them stress-free atmosphere keep changing your filter media as per the guidelines provided by the manufacturer. If you lack concentration on regular maintenance of filter, toxins that harm your aquarium and its contents may seep in.
10. BE WATCHFUL
As already hinted a continuous everyday observation of your aquarium and its contents will naturally enable you to notice even the smallest change in behavior of fish in the enclosure. Do not ignore the minutest change, be it the activity of a particular fish, a spot on its skin or an unexpected failure of any of the devices connected in the aquarium. Remember it is a small tank and the slightest of environmental change within the enclosure may get blown up to be disastrous if ignored. Any noticeable change should be analyzed and corrected without loosing time. Observe, test and take urgent corrective measures to give a healthy aquatic environment to your inhabitants, to continue to derive that pleasure which you cherish!

Hope that it will be useful for your Nano tank setup!
