How easy are they to keep? Angelfish are relatively easy to keep. They can be fragile when small but grow up to be hardy, strong fish.

How big do they grow? Angelfish will grow to a size up to 15cm. The ones you will receive are around 1-2", similar to a 50p coin size.

What is the best-sized tank for these? We recommend aquariums of 100 litres or more to house an Angelfish however the bigger the aquarium the better. Due to their shape, they will do best in slow-moving water so make sure there's not too much flow or areas with low flow.

What is best to feed them? A good quality flake or pellet is perfect, but most importantly is to offers a varied diet. They will also appreciate feeds of live or frozen foods such as blood worms & daphnia. We have a wide range of foods at Delta Aquarium.

What water conditions do they require? Naturally comes from quite acidic water, so best to keep the water quite soft so would recommend a pH of 6-7.5 and a temperature of 25C. Most importantly keep stable water parameters and be careful during water changes to avoid extreme fluctuations in pH and temperature.

What can they be kept with? Suited to a medium-sized community tank, with Gourami's, Dwarf Cichlids and larger Tetra. Natural predators, they should not be kept with Guppies and smaller tetra like Neon's. Please see the compatibility chart for more information.

Where are they from? Originally they are from South America: Brazil, Columbia, Guyana & Peru. Most specimens available now are captive-bred. Ours Angelfish are locally bred, strong and feeding well.

Can they be bred in captivity? Breeding Angelfish can make an interesting project. Once you have a breeding pair they will readily spawn and lay eggs. There is plenty of information on breeding Angelfish.

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.
