Learn how to care for Marine FOWLR Aquariums. These tanks have easier upkeep and require less testing and supplementation than a reef tank. You can keep many fish who would generally consume corals and invertebrates, making it a popular setup choice for more aggressive fish.

Without anything to use for scale, it is hard for me to tell how big your tank is, but in general it seems very small. Also, the water that is in the tank appears very cloudy right now, so that would be the first place to start. Water quality is very important, and will make or break your ability to house and care for fish. I would recommend getting a good filter system (you can visit a local pet store to assist you with brands in your area, as I am not familiar with what you can get in India). Be sure to bring the measurements (height, length, width) of your tank, or the gallons or liters so they can tell you what capacity of filter you will need. Everything else will depend on what types of fish you get - if you plan on getting multiple fish, they will need to be small - a general rule of thumb is one square inch of fish per gallon of water. Depending on the species you get, you may need to also get a bubbler to ensure there is enough oxygen in the water for them, and you will also likely need to get some sort of substrate for the bottom and cage furniture (different species have different air requirements, and some are secretive and like to hide). You may also need a water heater, depending on the species you would like to house. But, depending on how small your tank is, it may be hard to get a water heater that will fit. The food type will also depend on what species you get, as there can be differences in diet type between species. I hope that gives you a place to start, and good luck!

It is very difficult to get a good biotope in a just 1 foot long tank unless it is a few feet high. You will not be able to keep fish in it, only invertebrates, maybe a few shrimp or sea anemones. It is much harder to keep the water healthy in a small tank,and the appliances needed for running a salt water aquarium cost pretty much the same (if available) as appliances for a larger tank. I suggest you join a club of salt water aquarists who will be able to start you off perfectly. Your local fish/pet shop should be able to point you to a club.

I would recommend using an aquarium thermometer to check the starting temperature and that the heater is working correctly. The heater should have a thermostat which switches on and off to keep the temperature constant. You can leave your fish in the tank during this process if you can monitor with a thermometer.

When used as instructed, plant nutrients and fertilizers designed specifically for aquarium plants will not harm aquarium fish. Allow new aquarium plants to settle and establish themselves before adding any fertilizers. Use aquarium plant substrates such as CaribSea Eco-Complete Plant Substrate http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=9087 to get your plants established faster. Seachem Flourish Advance Natural Phytohormone Supplement http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=33890 will help stimulate root growth vital for overall plants health. Even though you have plants with low to moderate light requirements, be sure to use aquarium light specifically designed for planted aquarium use (sometimes called plant lights) and have the lights on between 10 and 12 hours a day. You may need to adjust the photoperiod (the amount of time the light is on) depending on how your plants are doing and to prevent unwanted nuisance algae growth.

The Cowfish, or Longhorned Boxfish, is a marine species that should be kept only by experienced aquarists. When stressed, they can release toxins into the water which may harm tank mates. Pacman frogs, leopard geckos, corn snakes or bearded dragons are all easy to keep.
