Caridina "dark green" sp: color development from juvie to adult

I purchased some Caridina dark green shrimp a few weeks back and put them in my shrimp-only 5.5 gal planted tank. I had mostly juvies but one shrimp was larger than the others.

The juvies are not quite clear but greenish-clear and as they got older, the green becomes more pronounced. The first two photos are a juvie shrimp that's almost 1-inch long and the last set is of an "almost adult" at 1 1/2 inches length and much fatter than the juvie.

First the juvies:

In any case, I don't have a question. Just thought I'd share and say I'm enjoying the dark greens!

Love those shrimp and your tank! Did you dry start your carpet?

I'd be interested in your specs as well I also have a 5.5 I'm wanting to carpet.

It looks like HG not HC, which is a bit easier to grow.

I did not dry start. I just had wads of HC (yes, it's HC not HG) already from my 3gal pictope. It was growing really well there, and instead of trimming with scissors, I grabbed tweezers and pulled selective chunks of HC. I smoothed out the HC in my 3gal so there was no holes, and used the nice chunks to start carpeting the 5.5 tank. I put splotches of it apart from one another and used eco-complete on the bottom, black sand for the top so that the finer granules will give the HC a better chance to root.

I laid pyrex plates on top of the HC. The glass allows the light to go through. The HC was still pearling with the CO2. When the HC seemed better rooted, I took off the pyrex and the HC starting spreading out.

It's a paintball CO2 set up (1-2 bubbles per sec for 6 hours a day; goes off when the lights are not on). The lights are a homedepot $8 clasp lamp with a 6500k 24W compact flourescent light (supposed to be equivalent to 100W but that's not really the case when it comes to plants). I played with the height of the lamp when it seemed I was getting algae. I also have a second lamp with a 6500k 10W compact flourescent focused on corner where the other lamp cannot reach. Again, I play with the height so that I don't over light the tank and have algae problems.

I do regularly fertilize. Some think it hurts the shrimp. But so far, my shrimp have been doing OK. The CO2 is what I am careful about. I've killed a few by accident when the bubble count is too high.

The key with CO2 is water agitation and good circulation. If you look at the tank, I have sponge filters on both ends plus a regular Azoo 60 with shrimp prefilter guard. With plenty of water movement, and watching the bubble rate, I found a happy medium between having shrimp AND a nice planted tank.

Hope this helps!

FYI, the green shrimp are smaller than their peers (TT's are larger; and the PFR are way larger), so I think when I took the photo up close, the HC started looking like HG, but it is HC. If that makes sense...

Oh no, from the FTS it looked different. And I didn't think you were using CO2.
