My Sharks in HD

that sounds promising. If not doing it already, start feeding everyday. With multiple feedings, the introduction of high energy foods ( Tuna, Shad Roe ) and of course, mature females, you should start seeing eggs.
 
Alprazo- As for the Greys, which were purchased at around the same size, all within 3 months of each other. They were just shy of yearling - size at that pt of the end of 2011. The males are all mature from a visible observation. Large claspers, etc. The females have always been questionable to me...
I also just ended the Prazi treatment and I don't know if that will have impacted egg development and reproduction. I also lowered the water temperature tremendously in order to manage DO levels during the treatment. While the temp is still lower than usual I'm a bit hesitant to feed daily.
***Do you think that this is a valid concern? ***
I have recently been reading a bit about the rate of hermaphroditism in carpet sharks, specifically hemyscillidae. Makes things more confusing! But I have had eggs from one Grey female already, so no questions with her but the others... hmmm....

Cu455- Yea! I noticed that only after watching the video! The bamboo sharks have never actually attacked and killed a fish. The Catsharks definitely have, though. The bamboos go nutty during feeding and this video was taken just after all the food was all consumed, yet they were still in feeding-mode. The C. punctatum are long and slender, with a much more narrow snout and a very little bit of banding still visible despite being 30"+ in length. The Grey bamboos, which i have come to truly love, have a much more broad, squat look, with a broader compact snout and thicker across the shoulders. I'll look thru the video again and try to give the times for the the Greys!

Fishhuman- this pond was built 5-6 years ago after trial and error with other designs. It has been a constant work in progress, and a constant source of investment. I could not give you anything like an accurate dollar amount. The pond itself was overbuilt in order to pazt, a 90mil pond liner was used initially, then another 90mil pond liner was added, for redundancy. The pond build alone cost a few thousand, then the various tanks, in the adjacent room, that offer the natural filtration that I prefer to also include was slowly built up and put inline. The monthly electric, fresh/frozen seafood for the sharks/fish monthly, salt for WCs, water bill, etc. are just monthly considerations that are near $1000. Total investment for the last 6ish years, would have to be over $100k.
This can be done for less money, on a slightly smaller scale.
The electric, especially where I live, is what is probably the biggest PITA of all.

Fishhuman- I will try to give you a more direct answer to "how much did it cost to make this pond?", as in the construction of the pond, by itself.
However, I cannot at the moment, but i will soon.
 
The Sharks Underwater

The Sharks Underwater

I got to see the pond the other day and I have to say it is more impressive in person then in the videos. Even more impressive then the pond is the amount of organisms he has in his macro algae, worms, shrimp and pods. The whole setup is amazing.

Here is Griseums pond underwater edition. I thought the 45sec-55sec part was pretty funny.

 
Cu455 - Thanks for posting that up! Came out great! It was good having you by! The little female is settled in well.

Video gets good between 4 min and 5 min mark too!
A little embarrassed that the only bony fish with the guts to swim while the sharks get fed is the yellow tang I just brought in with the worst HLLE I've ever seen! But the dorsal, ventral and caudal fins are showing improvement!
The little brown pellets that are floating around are NLS I threw in before the sharks food to try and make the fish a bit more active. Failed!
 
With the increased daily feedings and a few other changes, the dusk and evening activity level has gone through the roof!!!!
I thought daily feeding might be too much as im running the temperature between 73.6 and 75ish. But after a few tries with different foods and the amounts of those foods each day, there's a huge change.
Thank you Alprazo for the tip!
Also, I've had a Venustus angel in QT for a couple of weeks. Along with a few other fish. I'm learning which foods the Venustus prefers from the mixed frozen foods and NLS pellets I've been offering. Of the spirulina brine mixed with Mega Marine and mega marine angel formula, the Venustus goes for the absolute tiniest of what is available, which i believe are the tiny brine shrimp. He's wary of eating out of the water column but he does nibble those who they float down to the lower quarter of the QT. As for pellets, 1mm Thera-A h eats every time once on the tank bottom. This seems to be inline with what a few other threads are stating too, over in Reef Fish forum.
The next step is deciding whether to place the Venustus in with the Marshall Islands tank, with the Multifasciatus, or a downstairs tank.
 
It's good to hear she is doing well. I just watched the video again. The grey does look like she is bulging from the sides a little.
 
Zoodiver- what happened? They weren't fertile eggs? Or it was a false alarm?
I get to see a much different behavior when I the pond/tanks remotely by way of the Webcams... The telecasts are much more active when I'm not present. The sharks are very active now all throughout the day, at specific times too.
The increased feeding has changed things quite a bit.
 
Never found eggs. Not sure if she laid them and they were picked apart or hidden, maybe false alarm...too many options. The mature male just relocated to a new home last Saturday. He's the first shark to help start a new breeding endeavor with a conservation group I help out. He's in a 2,000 gallon system. Soon he'll have other similar sharks (Greys, White spotteds, Eppies, Coral cats...).
 
Sorry to hear about that! I did a recent "inspection" on the sharks genitalia, and was able to get a brief video of each shark while I held it upside down and checked them out. All of the males of each species are definitely with calcified claspers, especially the 2 grey males. The only male that's now mature is the big brown banded bamboo.
So as for white spotted and Greys, something is possible at any time!

Glad to hear the male is moving on to fertile possibilities!
 
Typo in my last post !
The only male shark that is NOT sexually mature is the big Brown Banded Bamboo!
Hes got some growing to do still!
