We have found that the primary factors that will determine allowable density for raising angelfish are pH, feeding frequency, feeding amount, type of food, water change frequency, water change quantity, temperature and angelfish type. As you can imagine with such a list, the variation that affects what you can get away with, is tremendous. The other greatly varying factor is the expectation of quality. Some will happily accept angelfish that others would cull in a heart beat. Potential angelfish breeding or show stock should be given the maximum amount of room. For angelfish used for these purposes, we'd recommend starting by giving any that are over dime-sized, at least 3 gallons per angelfish. If over quarter-size, give them at least 5 gallons per angelfish and over silver dollar-sized, try to give them 7 gallons per angelfish. Once they are mature and starting to breed, it is best if you can give them 10 gallons each.
How Much Food To Feed 3 Large Angel Fish | My Aquarium Club
Simply put, you must offer a large variety of foods, multiple times a day, with perhaps multiple methods of presentation. While brine shrimp are far from a nutritionally suitable staple, they are often useful in jump-starting the feeding response in these fish. All of the foods mentioned above should be offered at this time, and macro-algae should always be available, and can be submersed and secured with a clip. Nori is a good option here. Once feeding commences on a given food item, you're in business! Well, at the very least you're on the way! Other foods should be offered at the same time in rotation along with whatever the accepted food is -often brine shrimp. Slowly but inevitably the list of accepted foods will grow, and you now have the ability to ensure the nutritional health of your angelfish. That wasn't so hard, was it?
What should I feed my angelfish
A big reason for the caution I'm advocating here is something that many aquarists do not realize about these fish, and that is that the moderately hardy to delicate species go through a prolonged period of acclimation - longer than casual observation will make manifest. The most important thing to keep in mind here is that their immune response often does not function at full tilt until months after they are seemingly established in a display tank. There is no hard answer to how long this period is, as it varies greatly from individual to individual and the circumstances involved. What this means is that you may have quarantined your angelfish properly, and he may be swimming around in your display and all may look fine and dandy for weeks. Quite often the reality is that the fish is still in a state of low-level stress, has not fully acclimated to the surroundings, and is moderately susceptible to disease still. At this stage, there are many things that can send the fish into a tailspin. Among these stressors are inadequate shelters, low quality of food or inadequate feedings, temperature or pH fluctuations, nitrogen spikes, and the one we are concerned with here, harassment by a tank mate.
