From what I've read, the yolk sac will disappear, and the shark will get a bit cramped and not move around so much, then one day he just pops out. As long as the egg has water flow for breathing you should leave it alone.

It's been a long journey to this point, and I'm excited just reading your story.

People have different reasons for not sharing information, it is their right to do so. If I had a 300G tank, I would be sharing it with both words and pics.... But that's me.

Hope your find yourself a daddy soon, the wait must be difficult. Let us know what it is for sure...

Thanks for the info. I will let you know when it hatches.

The wait is not as difficult as this is the first time with an egg. First time doing an egg. Kinda unsure of myself you thats why i was asking.

New at this forum stuff. Not very techy. If i learn how to put the pictures up and stuff I will. That isn't my issue.

I hope you won't leave our community over one incident. I for one would really like to see some pictures of your tank. I know nothing about shark eggs and I would like to see some daily/weekly picture up until it hatches.

In my opinion though, you are right to point out to the mob that we collectively can be a bit cynical. It can happen after reading countless posts of people with their first 55G SW and a new shark. I hope you don't take offense to the passion in the posts. That passion is why a lot of us are here. I am now tempted to ask 100 questions about your set up out of pure curiousity, but I'll refrain. Any details or pics would be cool though. I'm always out to see new systems and learn something.
If there is one mistake I made. Its starting with the egg... No experience has made me nervous. I didn't know what to expect. Seeing and reading are 2 different things.

For a month I didn't know if it was alive. Probably should have looked for a video or something. I didn't know what to look for or what I was looking at. Store just told me there was a lot of yoke so it would be a long time.

HN1 I'm not offended just trying. And trust me... If I don't get this right I will not do it again. I'm not trying to destroy something that I think is so beautiful and fastenating.

Again, I respect your first post. You were honest and did not offend. I understood your respectful post.
Thanks again.

You can use a flashlight to observe egg development and embryotic movement. The egg case shouldn't have any offensive smell or necrotic deterioration (fungus, etc.). Generally, an embryo is visible at 18 days and the first stage of development will end around Day 19-21 where you will notice consistent movement, gill formation, and "finnage." The actual embryo will also begin to color. Stage 2 is "Pre-hatch" ending around Day 35. During Stage 3 you will notice a more shark-like form within the case where most of the growth hastens from 90 days until hatch, which can extend from 120-160 days.
Maintain temps. between 75-80F. The higher the temp. the faster the rate of development; however, also a greater risk of lower oxygenation so keep the tank well aerated. The salinity should be maintained between 30-35ppt. As for food, the shark will feed from a yolk sac until hatch and often several days after. It may not accept food until the nutritional aspects from the yolk sac have been absorbed and you will notice a definite decrease in stomach mass. Do not try to gut-load/force feed your newborn as this excess food could very well not digest properly and rot within their gut.
Some sharks do not respond well to fine sand and need a bare-bottom tank for grow-out. Keep an eye on any redness under the body frame and fins where irritation may set in.

Just wanted to explain my post. The first two sentences were written to another poster that deleted his post after I posted my response. That was not directed to you. Sorry if it looked that way but it was directed to him. I then proceded to give my opinion on sharks in this hobby. Everyone has the right to post their opinion whether it`s liked or not and as long as it`s not flaming or attacking which my opinion was not. I then proceded to wish you luck stating that if you have the right equipment and know how you should be OK. I`m trying to see what the problem is. If someone answers something that you dont like or does not answer it like you want them to then that is still their right to do so. Aquarium forums are great because everyone can give their answer or opinion based on their experience as they see fit. It`s up to you to process that advice and take what you want but not to ridicule or trash their advice. Let`s all try to keep that in mind as we ask questions and start threads. Again Good luck on your shark egg and your tank.

All I asked was about my egg and info on what should I be seeing in its progress and should I section a part of the tank.

That is exactly my point. They didn't begin to answer the question. There is nothing about an egg in their response. So how is their answer based on experience. I didn't trash their advice to my question because they didn't give any advice to my question about egg or sectioning my tank.

In sports: What does asking what a football looks like. And you answer How big is the stadium?

And pardon me.... If you say as moderator they can give me their oppinion on my question as they see fit(although they really didn't address my question).
Then why can't I give them my oppinion on their answer..... As I see fit.
My oppinion was next time address my question....

Your quote:Let`s all try to keep that in mind as we ask questions and start threads.

Ok, and if that is the case. Why don't you add the key component....

Lets try to keep in mind the question!!! Because that is what you are really supposed to be answering.

Thanks for the wish of luck on my egg. I accept it. Good luck on your forum.
