A Plecostomus is a Tropical Fish from South America. They are often called "Sucker Fish" because they are seen sucking on the glass. They feed mainly on algae and/or algae wafers when they are kept as pets.
Koi are a cold water fish as are Sturgeon. Plecostomus are a tropical fish so they should not be kept together in the first place. Plecostomus are a large but peacefull algae eating fish and they are no real threat to any other fish.
Betta fish should be kept in water 72-82'F(22-28'C).
Oscars should be kept alone so they don't eat any of your other fish of fight with other Oscars. Oscars also grow very fast and as they do they become more and more aggressive. They can sometimes be kept with a large plecostomus if your tank has plenty of room.
No, they need air, filtrtion and regulated temperature. Not many fish can be kept in bowls.
No. They require totally different conditions. Goldfish are cold water fish and should not be kept in water above 70F. Plecostomus sp come from the tropics and should be kept in water above 75F. If you keep them together one or the other will be in conditions that do not suit it so it will probably sicken and die.
A guppie is a tropical fish and should be kept in an aquarium with other tropical fish, a goldfish is kept in a bowl or tank in cold water - the 2 cannot be kept together because of the different in the temperature of the water
Water temperature in the aquarium should be kept in the 75-80 F range.
Mollies are tropical fish and should be kept above 70F. Goldfish are coldwater fish and should be kept below 70F. They should NEVER be kept together.
Well, the correct answer is no. But when I kept my tank at room temperature, I had no problems.
They are tropical fish. But are found to be more tolerable of temperature. If the surounding air temperature is kept reasonable and therefore the bowls water is kept a reasonable temperature then it is possible, but most of these types of fish grow rather large in time.
tutles and fish should NEVER be kept together
