Guppies will alway over populate a tank in time unless you take matters into your own hands. But if you let nature take its course you should be fine for a while. With plattys,mollies and guppys, all of which are livebearers and breed like rabbits, ultimately your tank may become overpopulated.

How many fish can you have in a tank per gallon?

While the one-inch of fish per gallon rule is a reasonable yardstick, it has its flaws. To be safe, with big-bodied fish like goldfish and cichlids, one-inch of fish per two gallons of water is a safer rule to go by.

How do you determine how many fish are in a tank?

You can use the surface area rule to help calculate how many fish you can stock safely. You arrive at this number by multiplying the width of your tank by its length (width x length = surface area). If you use this rule, you can usually stock one inch of fish for each 12 square inches of surface area.

Do fishes pee?

Fish urinate either through their gills or through a "urinary pore." The latter eliminates urine that has been filtered via the kidneys. Saltwater varieties excrete most urine through the gills, while freshwater fish do so through the urinary pore. Freshwater fish have to get rid of all the water they take in.

How do fishes sleep?

The simple answer is yes! They are sleeping, and they can sleep at any time during the day or night. Fish do sleep with their eyes open, because they don't have eyelids (except for some sharks) to close! For fish, sleep is more like a resting period similar to a daydream that humans might experience.

Do cichlids need a heater?

Check the temperature your African cichlids will need before you bring them home. Tropical fish need warm water that's between 73 and 82 degrees Fahrenheit (23-28 Celsius). Choose an aquarium heater with 5 watts of power for each gallon of water in the aquarium. A large aquarium may need a heater at each end.
