You don't have to have a bubbler in a tank it is mostly just for show but it can also help kick up crap in the gravel so your filter can suck it up, help with water circulation in the tank, it can also help you keep a constant temperature in your tank which tropical fish need to live, and also if you have to many fish in your tank or your tank is to small for the fish you have they might not be getting enough oxygen which the bubbler can help replace but if you have the right number of fish or the right tank for your fish the filter and water changes should replace enough of the oxygen. Remember the basic rules. 1 inch of fish needs a minimum of 1 gallon of water except for goldfish which its one inch of fish needs two gallons. Every tank needs a permanently running cycled filter. :- Every tank needs at least 25% of its water changed every week and it needs to be gravel vacced once a month. You also need a heater for any tropical fish because they do best at a constant temperature of 78 degree's.

This is with every fish, the males bottom fin is like a spike as the females are like a circle.
Yes, guppies come in many color varieties including red. If there are two male guppies and one female guppy, the female will most likely become too stressed and will die. Always keep more females than males!
