All the hydra are gone.

I have had problems with hydra before, I've had whole aquariums covered in them. They are pretty cool, some snails seem to eat them. I've always wanted to grow the green hydra that have algae in them kind of like corals. I had sponges once as well but this is for another thread I am sure... Paddlefish are doing great, I am watching them feed on daphnia as I type. Really great fish...

Yes, but how do I get it to stop doing that!

Assuming the lens of your camera doesnt extend past the frame, Ive found it best to hold the camera up against the glass, so that it wont attempt to focus on the glass. Although it is difficult to track a moving fish so close to it, you do get better clarity when you get a shot, also using a flash doesnt cause as much glare, because the lens is against the glass.

The camera is a Kodak M1063, thanks for the suggestion, i'll give it a try and see if i can get some better pics. thanks again...

I transfered the smallest fish that was being prevented from reaching pellets by his larger tank mates to a daphnia tank, he has recovered his chubby look and is doing well, i like for my fish to be chubby, lol

About your camera, according to the kodak webpage, macro wide setting allows you to be as close as .1 meters, so you need to be sure the fish is at least that far away from your lens, and that is with no zooming.

Another thing that might clear up photos is using the "sports" setting which will speed up the shutter. I believe in sports mode you need to be .6 meter away, although if you have the ability to do manual settings you may be able to do high speed macro, thats how I get photos of freshwater invertebrates swimming. I get about one good photo for every 50 taken, good thing its digital and not film.

Also, set the resolution to max size which is 3664 × 2748 on your camera, then you can take photos from a distance (sports setting) and when you crop them, they will look closeup.

The paddlefish are doing well, i have split up the biggest fish from the smaller ones until i get the 75 set up. They are all eating aggressively and are still awesome!

I've been told the link to the video of my paddlefish didn't work, try this one...

The paddlefish are still doing well, my daphnia culture is producing daphnia at least 2 shot glasses a day and the paddlefish are eating it like candy. They are also taking pellets with gusto and so far are really great fish.

After more than a month of watching them feed and swim i wonder just what that paddle is for, the best guess i have so far is it allows them to swim stabilized as they feed with their mouths wide open, almost like a fin or plane that lifts the head as they feed.

I am still enthralled with them, all I need now is some shovelnose sturgeon!

The 'paddle' is full of extrasensory organs used to detect large amounts of tasty tasty plankton and daphnia.

Oh I am sure it is, the snout is a ploy to increase the surface area of the taste/electrical sensors, much like catfish whiskers and sharks hammerheads but to watch them in captivity it would not be obvious.

So far these fish are doing great, I continue to be enthralled with them, I don't know why but my daphnia cultures are producing like it's spring time and the paddlefish are eating on the hog... so to speak....

very cool! I'd kill to try a few of these in my backyard pond myself.

I wonder if anyone has done any experiments on the hydrodynamics of that paddle(perhaps it does work like the cephalofoil of the hammerheads). I recall that paddlefish that suffer excess damage to it do not survive?

It does look like it acts as a sort wing to keep the fish balanced. Injuring it would probably make it very difficult to balance.

A sudden crazy thought (I know I'm full of them) I wonder how much variation there is in the shape of the paddle? If there is a little bit maybe that could be magnified through selective breeding and over several generations you could get a "hammerhead" paddlefish? :cool:

Funny you should mention the paddle shape. In my business, the rostrum is a deterent. It takes away from the overall yield of the fish if sold for meat. My thought was to work on getting the rostrum shorter by selective breeding. According to my mentor, Dr. Steve Mims, the genetic structure is such that I could never get it to happen no matter how intensively I tried. Also, according to Mims, paddlefish that have lost their rostrums do not show any adverse effects and will grow the same as one with a full rostrum. We are working on using the cartilidge in the rostrum as a sustainable alternate to shark cartilidge to stave off the finning slaughter of sharks for Chinese soup. So far success has been limited.

We did get a batch of fish last year that had squared-off rostrums, Literally looked like they were cut with scissors. Had to be a defect because they all died three weeks after they hatched. That's why we include at least 5 fish in our yearly broodstock.

My paddlefish continue to do well, they are so small compared to their hatch mates! the biggest one i have might be 6" the smallest about 4". I'll try to get some pics soon to compare with the ones bigfishfarms has posted.... I still have daphnia by the way, I am feeding the daphnia heavy on bakers yeast....

WOW I just fed my paddlefish some daphnia and as watched them feed I saw one swoop down and grab a black banded sunfish and swallow it! Evidently our mild mannered paddlefish are not so mild or mannered! The paddlefish was about 5" and the sunfish was about 1", I wonder what an adult paddlefish would do to a school of minnows, or a school of shad? I've noticed what looked like the paddlefish lunge at an otto a few times but he missed so badly I figured it was just a fluke.

I saw a paddlefish grab another sunfish today, this time the sunfish got away! That video is about a month old, i took a new one today, it takes so long to upload them it's crazy, the new video will take 4 hours to down load....
