How many eggs will a female angelfish lay at one time?
This will be determined by genetics and care. There will be some angelfish in every spawn that will grow up to be poor breeders. You must be willing to not breed these fish if you want to avoid taking a step back in this area. The number of eggs per spawn, will also be affected by frequency of spawning. Female angelfish that tend to hold their eggs for longer time periods, will usually lay more eggs at a time. Conversely, an angelfish that lays every 5 days, will probably put down fewer at a time. Feeding, temperature, water changes, etc. will affect the number laid. It’s obvious that the best care will produce the largest number. We’ve seen spawns that approach 2000 eggs, though the average for a females regularly laying with good care, would be in the 400-500 range. There is no lower limit. Pay particular attention to raising angelfish properly and they will reward you with lots of eggs.
