Angelfish eggs/fungicide

I have a pair of angelfish who have spawned when seperated to their own tank a few times in the past and have tried to artificially raise the fry but haven't gotten past the just free swimming stage. my question is that I am using this fungicide called liquid fungus cure from API that turns the water a lime green. It says its safe for all freshwater eggs but I feel like I may be seeing more white eggs than I should be. At the moment I have the mother raising the spawn (she had the poor father backed right up into the corner of their 20 gallon bare bottom tank).. Theyre almost 3 days old.. Almost to the wiggler stage.. Yayy!! Has anyone used this fungicide and had success?

 

When I first started with angels I used methylene blue. I personally don't use a fungicide when raising angelfish eggs now.
If they turn white in the first 24 hours that means he is not fertilizing the eggs good. Good clean water will go along way towards the eggs surviving provided they have been fertilized.

my male usually has a pretty good percentage fertilization, but maybe he is the reason so many turn white. At what point would they stop turning white ig it were his fertilization skills at fault does anyone know? I do 2 nearly 30 percent water changes every day in the hatchout tank, should I be doing more than that?

 

to FishLore!

Any eggs not fertilized will turn white in the first 24-36 hours. How many times have they laid? Sometimes it takes quite a few times before they get the hang of covering all the eggs.

25-50% water change once a day is plenty. You may be disturbing the eggs or changing the water parameters too often with two water changes each day.

what size tank are you using for hatch out?

I agree with Carol. If the eggs turn white in about a day, they were never fertilized. I have a newly mature male who is more interested in guarding the spawning site (no others in their tank) than in fertilizing the eggs. But, after 4 or 5 spawns, he finally figured out that he needed to fertilize the eggs instead of guarding the site.

I have never used the fungicide product you are, so cannot comment on it. I've taken to adding nothing or to using hydrogen peroxide in the hatching tank. Not every egg will hatch; and not every hatchling will survive the first 2 weeks.

 

well theyve laid maybe 4 times in a separate tank, they won't lay in the community tank. And usually I have them in a 20 gallon to lay the eggs and at the moment the eggs are in a 10 gallon. Both parents are removed now, the mother started snacking on the eggs so I took her out. The male wasn't allowed (by the mother) to go anywhere near the eggs right after she finished laying so I took him out way before.

 

catsma, how much peroxide do you add to the tank per gallon? Ive heard this technique used before but never knew how much is supposed to be added. I am curious about this and may try it in the future!

 

10 drops peroxide per gallon water. Once you have wrigglers, stop dosing it.

Only use HP in a hatching tank as it can affect the bacteria that has colonized in the adult tank.

 

alright. I have wigglers now so ill try that on the next batch. Thanks!
