Pretty cool new variant...here's a couple of slightly blurry snaps I took before the lights went out last night.

These are great! What did they set you back?

More than I intended to spend!

At my LFS, red cherries tend to be around the 3 mark. These were 8 but the store manager gave me them for 7 a piece which was nice of him. I know I can get them online for 5 but my LFS is invaluable to me so I'd rather pay more and get continued excellent service (they have helped me out with broken filters in the past which was a real life-saver).

They were SUPER sensitive when acclimating them (three hours) and I wasn't sure if they would actually live as a few of them were lying on their sides and looking stressed after I introduced the first ten drops to their bag. :eek: However, I gave them plenty of time and very gradual, but increasing, acclimation and they perked up after release. I didn't see any bodies when I left for work this morning so I'm hoping they'll be a success. They're certainly a striking contrast to the reds.

The store also had some fascinating red-nosed shrimp (Caridina gracilirostris) which looked fantastic, and were around the 10 mark. I'm going to read up on them as they would be a nice addition and won't interbreed like all my others will - although a quick Google of this species suggests they should be kept in brackish conditions.

Black and white Taiwan bees were at a similar reasonable price (around 10), although I wasn't sure if my water was good enough for them (too hard) so I left them alone as I'd really feel the pinch if any died on me. They also had some crazy priced high grade shrimp for about 90 a piece! Not touching them!

Whew... that is just crazy! Ill stick with my nice RCS and maybe a tank of blues after a while. I know a couple local breeders so I may be able to find some cheap. Great to know about water conditions. Do you have an accurate species profile on them?

For the blue jellies? The species profile would be the same as RCS as it's the same species...just a different colour variant. You can get yellows too.

Ya know I figured that... see I can keep them in my liquid rock but I am iffy on them if they are that hard to acclimate...

Well, I'll let you know if I lose any. I'm in London which has pretty hard water (7.5pH out of my tap). My LFS keeps their shrimp in half London tap water and half RO water.

I must admit I've never had stress-free acclimation with shrimp. They ALWAYS look really stressed and lie on their side/back for a couple of hours before recovering. I'm normally convinced I've killed them. I'm not sure why as I do it so slowly and ensure the temperature is stable, aerated etc. For these I did it by hand (adding ten to twenty drops every 10 minutes and aerating/circulating with a 5ml dropper - talk about labour intensive care!) as it was too cold in our flat to acclimate in a bucket. With these I also dumped all the bag water into the tank, which I don't normally do, but I wanted every chance of diluting the hard water in this case. I do hope it pays off.

I'm considering changing my maintenance routine and doing 10% water changes every evening, instead of 50%-60% a week, to keep things more stable for them. I've also added black alder cones to the tank which I've read can be beneficial.

Let me know how it works, these shrimp are really pretty and I could see me doing a species only 5 gal setup. Really a great find!

Very nice looking; good buy firefly.

Here's a few more snappy snaps...all blues looking well I'm pleased to announce. There was the slightest milkiness in the water so I tested for ammo, trite and trate but readings were 0, 0, ~5, so all ok. Might be the alien water I dumped in last night. :shrug:

Here's a hybrid Cherry Red x Rili

Free swimming! These are so hard to catch...not quite sharp enough.

A red for comparison.

My favourite shot so far:

Another ok contrast example.

Can you share what camera settings you are using in these shots?

Knightia
05-24-2013, 08:30 PM
Here's the stats...

Camera: Canon EOS 550D
Lens: Canon Macro 100mm
Aperture: f2.8 (some other shots were f3.2, f4 or f5.6)
Exposure: 1/200sec (some other shots were 1/125sec and 1/500sec)
ISO: 3200 (they'd be less grainy at lower ISOs and were I more patient I would use it and sacrifice the exposure time)
Exposure bias: -0.3step (I find tank shots tend to have blown highlights a lot of the time...I could probably address this by switching from spot metering to evaluative, although that can throw off the autofocus...I'm too lazy to use manual!)
Other: No flash, spot metering, aperture priority setting, autofocus.

Hold your breath when you squeeze the shutter to avoid camera shake thumbs2:

Look forward to seeing your shots :ssmile:

Those are neat shrimp, good luck with them, I hope they continue to thrive in your tank. I really like the last picture of the red and blue together, but the free swimming is my favorite.

Those are awesome! I'd love some, but they'd get gobbled up by my fish.

ALL of those pics are awesome, IMO...thanks for sharing firefly...my daughter wanted those blue jellies to start our shrimp keeping experience, but the price and my 0% experience with shrimp steered me towards RCS, which we enjoy daily

Great little shrimp you got there, Firefly. Love the photos, especially the one you're most fond of. That could have won POTM.

I just bought a macro lens, so I hope that I can get clear close-up shots of these bite-sized little morsels... I mean tiny creatures. =X

They're lovely to photograph...easier than fish! A macro lens is a huge help. You just can't get the same depth of field with a compact.
