So you replaced your fine sand with coarse sand? If so, coarse sand is not a good substrate for sharks. It will irritate and potentially damage their stomachs, especially with babies. With that large of a water change/disturbance, I would wait longer than a week for things to settle down. More like a few months. Were you not running a skimmer on the tank before? How about live rock and a sump? I would consider these all basic requirements for any saltwater tank, especially a shark tank. Getting a newborn to start eating is challenging enough, so anything you can do to improve the environment is a major plus. Also, any measureable nitrite should be a concern (assuming the tests were accurate) in an established tank.

Tried to only quote part of comment but guess I did something wrong.

Sand: we had very fine play type sand in the tank and it was a mess, packed really hard and made using a vac on the tank impossible. We went with a corser bigger grained sand but it is still a softer sand and according to manafacture and LFS that has several sharks it will be best.

Protien skimmer: no there was not a skimmer on the tank, there is now one and after seeing the nasty stuff it takes out of the water we will not be without one again.

Live rock: there was about 35 pounds in the tank, it now has about 75.

Sump: N/A

Please keep in mind that this (shark egg) was not a purchase or decision made by us, it was a "surprize" gift to two of my teenagers by a "well meaning" (idiot) relative, we came home and it was in their tank.

Now that they've had a pup hatch they have chosen to try and hatch another one and are trying to get their tank in the best condition for that.

Other than this weekend they have been checking the water parameter daily. If they are not holding where they should be they will wait before they try again.
 
being of a very curious nature I was trying to find info regarding the mortality rate of brown banded bamboo sharks, as I was searching I came across this thread from awhile ago that didn't answer my question but was really interesting and seeing this thread is about hatching shark eggs I thought that other people including the op might want to read it as well, so here it is

Dang...not very good numbers...I may still get one. :D

I know I would be heartbroken if it decided not to hatch/live though. :(

Potential Problems: This species does appear to have a high mortality - due to attempts to hatch them from eggs. The pups also have a high mortality rate during the first month, when about 50-60% may die due to lack of feeding or stress related to the hatching process. This species has also been known to suffer from Goiters, usually caused by a lack of proper vitamins/minerals in the shark’s regular diet.

Oh goodness, THAT book is back!


That info is wrong. And Scott Michael has never actually kept sharks.

High mortality in pet stores/pet trade is due to pet stores / pet trade not understanding step #1 about having and caring for a shark's egg.

Sharks in the egg are MORE sensative to any changes going on than a pup will be. Everything from handling of the egg, exposure to air to acclimation into a new body of water will have a HUGE impact on them.

First off, many eggs sent out aren't even fertile. So those add to the 'death toll' count even though they shouldn't.

Many are squeezed too hard, damaging the yolk and the growing embryo.

Many people just toss them from tank to tank... they need to be slowly acclimated just like any other sensative shark.

Many get air trapped in the egg, which limits the ability of the embryo to develop correctly.

Many sharks that do hatch are born into poor environments or to people who don't understand the proper ways to get them feeding. So they die shortly after hatching.

All carpet sharks CAN and WILL suffer from goiters if not cared for properly. It's due to a lack of iodine in the diet (because the way iodine breaks down quickly in prepared foods). That is why it's VERY important to understand shark nutrition when getting into these animals.
 
Oh goodness, THAT book is back!

LOL... I can just picture the look of complete disgust that came with that comment,

I will ignore all info from said book.

So basically you feel that the statistics are due to human error rather than nature? thats nothing new unfortuantly.

So I know (or think I know) that the eggs should not be taken out of the water at all and transfered to the bag while under water, and dripped. Also try and purchase an egg that you can see movement in already, floating is a really bad sign.

we figured out candling the egg buy putting it into a ziplock under water then using a flashlight to candle then replaced it under the water so it never was in the air, is this a good method?

so would you consider writting out the method & tips that would help those of us that want to hatch eggs have the best success?
 
Subscribed.
 
Maybe not a look of disgust, just laughing. I feel bad because so many shark keeper hopefuls end up getting that book, and it costs them in the long run because they follow it so closely.

Probably the biggest downside to an egg is that you have no idea what it was put through prior to you seeing it or getting it. I always suggest buying sharks that are hatched and eating for most beginners. Other than that, once you have one in needs to be treated like a shark pup (except for feeding of course). Acclimate properly, normal light cycle, good water quality, good water circulation. Once it hatches, don't feed it right away, they need a day or two in order to finish off using up the end of the yolk sac they just absorbed prior to obtaining nutrition from feeding.
 
The cubes he was feeding is called shark and ray formula , they dis continued it .. google shark and ray formula .. you will find the red cubes.
 
ok also I have THAT book....lol it was saying that the banded sharks can live in 70 gallon s tank a bunch of stuff that aren't reliable. I got i now....because of the pics lol
