It depends on the length of each side and the height of the tank.
About 29 gallons
For a 2007 Ford Fusion : 66.2 liters / 17.5 U.S. gallons
Its a long explanation how but it should be about 25 gallons
Hexagon Tank: 44 pentagon gallons
I would advise you to get rid of the Jaguar cichlid (Parachromis managuensis). These fish grow too big for a 10gal tank.
Fish can disappear in a fish tank due to hiding in decorations or plants, being eaten by other fish, or jumping out of the tank.
Hold the fish down and throw out of tank
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.
That depends on what you mean to say. For example, if you have one angel fish in the tank you could say "That's the fish's tank" meaning that is the tank for the angel fish. If you also had a couple of clown fish, you could refer to the tank as belonging to all three fish by saying "That's the fishes' tank." Slightly different spelling and punctuation
if you have a goldfish, try bi-orbs and hexagon fish tanks. They are available in a lot of different kinds. If you want ones for tropical fish, it is easy to find hexagon fish tanks. just look in a "fish store" or just ask local people. The other means to do this, is to shop for it online. Places like Amazon and eBay have a bunch of different items available.
Yes, but depending on how big you or the tank is.
Not in its self. The fish could jump out of the tank and land outside the tank, though.
