What is best to feed them? Mostly a herbivore, Brisetlenose pleco will graze off algae that naturally grows in the aquarium and adding bogwood will be beneficial as they will gnaw from it.

We have a great range of foods available at Delta Aquarium.

Many species are found in the rivers and floodplain areas of the Amazon Basin, but there are also species elsewhere in tropical South America, as well as two species, A. centrolepis and A. chagresi in Panama. Almost all bristlenose pleco are commercially bred and the fish that you receive will also be tank bred.

Answer: If you are thinking of keeping tropical fish, you need to know about the following main things: Size of your aquarium Firstly decide how much space you have for your new fish tank. Always go as big as you can fit, the bigger the better with fish keeping. Deciding what to fish to keep This will depend on the size of your aquarium. Research how big a fish is and will grow to. Small community to medium sized community set-ups are best to start with, unless you’re looking to create a biotope or species tank. Cycling your aquarium This is a very important part of keeping your cold water or tropical aquarium. Your filter is just a sponge and is no different than your washing-up sponge…until it’s “cycled” and loaded with beneficial bacteria. Maintaining your aquarium You should clean your tank on a weekly basis. A small 10-20% water change will help remove any build up of waste. Siphon your substrate and clean the glass, this will keep your tank nice and clean for your fish.


Answer: Yes, tropical fish will require a heater. A heater ensures the temperature stays steady during the course of the day. Generally, 25°C is the optimum temperature to keep most tropical fish, this is similar to what they are used to in their natural habitat.


Answer: The equipment you will need when it comes to caring for tropical fish include: A suitable fish tank Aquarium lighting Substrates and aquarium plants to help create a healthy ecosystem A filter system to keep your water clean and clear An aquarium heater A thermometer to keep to checks that the temperature is stable Aquarium test kits to check pH, ammonia, nitrite and nitrate levels Cleaning tools


Answer: In general, most tropical fish thrive on one or two feedings per day. You’ll need to adjust the quantity of food according to the size and quantity of fish in your tank. If your aquarium is new and you have just added your first fish, feed every other day and count the amount of food you are adding. A “pinch” is not accurate enough and may lead to overfeeding your fish.
