I've had freshwater tanks for years and in my opinion the bigger the better. Recently I've had my angelfish spawn! This is new and exciting for me, but I seem to be hitting a huge problem. Two to three days after hatching, 90% of my fry are dying. I'm desperately looking for some help! It's heartbreaking to wake up in the morning to dead babies. Am I missing something?? I hatch out in a 5gl tank treated with mb, 50% water changes daily to remove mb. Too fast? Baby's water temp is 79 degrees, Ph 7.4, Ammonia, nitrite and nitrates are 0. Any ideas?
