Yet another week has passed and there are only a few small items to report.

This weeks picture



As you can see the CRS are getting large. I am checking often for eggs. Frankly I am a bit disappointed in the coloration they are showing in the stripes. The white area is not as pure as I would have liked and I am looking at acquiring another batch from a different source. I think I will be able to isolate some of the better ones and get a decent line going but it will be a good bit of work.

Speaking of isolating and working on bettering a line. I have identified 2 male and 2 female Cherry Red's that are of as a working title "Super Red" and have them paired off in separate tanks. Males have fully red bodies, much more so then typical. Females are a deep red with a distinct deep orange stripe down the back. My photo skills lack in capturing the beauty of these, but I am working on it.

This week brought a new addition, S was kind enough to part with some of his lovely Tigers. He has some for sale too, and while they are still small as juveniles he was kind enough to send me one pair of more mature ones. They are striking. I do find they like to hide a lot more then most of the others, or it's just new tank jitters still. Time will tell.

The Red Claw female is still carrying and will be for the next few weeks. I understand it take 5-6 weeks till the eggs hatch. Their normal fare has been supplemented with snails. Very interesting watching them pull the snail from its shell and devour it.

I've also been experimenting with a new food in one tank this week. I came across some "Snail Crisps". I found these on Aquabid and after some discussion with the maker of them and securing an ingredients list she sent me a small package to sample. The shrimp attack it with gusto both times I've fed them Whit it. What I find particularly appealing is they have a very high Ca level both from the Ca powder and the eggs shells used. All the greens used are all high in Iodine too. I've also seen these type of product called Snail Snax, Snail Cookies and Snail Trail Mix, some of them do have added copper.

No new additions are planned for the next few weeks, with the midsummer heat I'd rather not play with shipping if I don't have to. I do have some irons in the fire for some interesting Nerites as well as some other shrimp and snail varieties.


Till next time...

I had similar experience. The juveniles are more attractive, they have more white bands. However, as they mature, most tend to lose some of the white areas, either turning clear or turning red. Out of 6 adults I currently have, only one I would classify as close to an "S" grade, the rest look like whats in your picture more or less. Out of two dozen of my tank bred juvenile app. 2 months old, many look very nice with strong white areas, I wonder how many can keep it this way.

Are you talking about crystal reds or cherry reds here?

Good point.

Cherries.

I edited the post to reflect that. Thanks for picking that up.

This week greets us with some new arrivals. I was at the lfs with a few other folks from GWAPA after the monthly meeting and tucked away in unmarked tank were these.





I don't know what they are either. I'm open to suggestions.

The bottom pic looks like the chameleon shrimp that I had. Does it have one long arm.





The other one ,if it's different, looks like the red-spotted shrimp that I used to have.

No long arms and the rostrum is less pronounced too. They have a definite Caridina body structure.

Gnatster,

The top one and the right one on the lower photo... Do they look sort of like this?:

http://pg.photos.yahoo.com/ph/mizmo_...7a.jpg&.src=ph

and this?:
http://pg.photos.yahoo.com/ph/mizmo_...3c.jpg&.src=ph

And here's the best photo I could find on-line that resembles most closely what I have (7th photo down on the page):
http://www.crusta10.de/index.php?page=7&sideid=news_de

Nobody seems to know what they are. I've seen photos of them as "Macrobrachium sp." but their pincers and arms seem even smaller than my cherry red shrimp's. I've also seen the same shrimp labelled as "Caridina sp." (as on the linked page) which I think is more accurate. One on-line shop is calling them "red dragon shrimp."

These guys really like to hide. The first one I got for free when I spotted it in a container of "algae-eating shrimp" (which usually only consists of Amano shrimp and Malayan shrimp). I think I got it back in January or February, thinking it was going to die like all of my small shrimp usually do. But just when I was sure it was gone, it would show up. As far as I can tell, it's still alive. I bought three more from another shop, and they have no idea what they are, either. But they're dang hardy since they're all still alive.

Also, after a few weeks in my tank, they turn a beautiful sort of brownish-red. But when I bought them, they were clear or white with that distinctive red "swipe" on its body, close to its head, and that red line down the middle segmentation line across its back. It's not particularly fancy, but nice enough... At least they don't die on me left and right.

The one on the left on the bottom photo looks almost like one that was called "Indian zebra shrimp" at Aquatic-store.com. Hard to tell from the photo (no offense).

Awesome set-up, BTW. If you get the industrial model of this shelf, they're rated to support up to 800 lbs. per shelf. But this only if the weight is distributed evenly. At least you don't live in earthquake country .

-Naomi

There are two areas where I get the most questions so I thought I would discuss them this week.

Food and Feeding

People always ask me what and how often do I feed, if I feed at all. Rest assured, I do feed the shrimp, for the volume of them on hand there I cannot grow enough algae to keep them satiated. Like anything else we keep a good variety off foods is important to meet their nutritional needs. However one has to be careful with many of the commercially available products on the market and reed the ingredients list carefully. Many of the algae wafer brands we all take for granted are "clean" contain copper sulfate. While occasionally a small amount of copper is probably good in the diet prolonged exposure to these foods in my observation have led to large die offs. Currently I use a wide variety of foods including:

Hikari Crab Cuisine
Hikari Algae Wafers (these are copper sulfate free)
Two Little Fishes Sea Veggies, multiple varieties
Cyclopeeze Flake
HBH Shrimp Pellets
Kens Fish Earthworm Pellets
I also have been feeding with great success a "Snail Cookie" product that once I had read the ingredients I just had to try some. The picture below shows how the shrimp (Juvenile Cherries) swarm to the food. That was taken within a few minutes of introduction. I am taking to the person that makes these and hope to offer them for sale soon.

Another food I want to try is a Japanese Crystal Red Shrimp food product. Hope to have some sent to me in the next few weeks.





Water changes

Another frequently asked question has to do with water changes, How do I do then, are they a pain for that many tanks and how ofter are they preformed?

In short, weekly 50% changes are done, every Sunday right before I sit down and write this weekly report. Using a 5/8's dia hose I drain 50% into a bucket watching to be sure I don't suck up any shrimp. Refills are RO water that has been mixed to the parameters desired the week before and allowed to age and mix all week. After I fill the tanks back up, with hose attached to a pump, I drain the rest of the water on the vessel outside to the grass, dump in pre-measured mix of Equilibrium and buffer and let it fill. Once the pump is submerged it's turned on to mix and when it starts to get cold again I'll keep a heater in there. A float valve shuts the water off when filled. All told I spend about 1/2 hr to change do all the 12 tanks.
