normal rule for fish in a tank is: For every 1 inch of fish there is 1 gallon of water
Bowls are not suitable containers for any kind of fish. The basic rules for keeping any kind of fish successfully are . :- 1 inch of fish needs at least 1 gallon of water. (Most sucker fish grow to over 5 inches) :- Every tank needs a permanently running cycled filter.(This converts the Ammonia that is created by all fish into Nitrate):- Every tank needs at least 50% of its water replaced every week.(This stops the build up of excess Nitrate) A heater/thermostat is also needed for sucker fish because they are tropical in their requirements and need to be kept at around 78F. If you stick to the above rules a fish will stand a chance of survival. If you miss out on any of the above I can guarantee that your fish will have health problems constantly and will die before it should.

Any fish with a underslung suckermouth can get labelled as a "sucker fish". The Pleco family consists of more than 800 species getting anything from 1" to close to 40". Then there are lot of other fish with that kind of mouth, including some freshwater Gobies and some types of Cyprinid like the Siamese Algae Eater. And then there are Chinese Algae Eaters too. Basically, there is no one species that is called a "sucker fish"!!
