Thanks, Mustafa, it's been a lot of fun. This Spring saw a total of about 9 berried females. I thought they were done several weeks age, but this last week 14 larvae appeared. Mommy must have been hiding. In total I figure the tank added another 100 or so new denizens. A bittersweet update: My wife,...

A quick update. There are now 7 or 8 berried shrimp. One has released her brood, another is in the process. There are 10, or so, larvae floating around.
It has now been 6 years for the tank, with no food added.
Hope everyone is having a nice Spring and Easter season.

Hmm. Nothing else has changed with the tank (that I can think of). Maybe just a bigger population with more individual variation? The number of berried shrimp has stayed at 3, so this is not a reproductive explosion like I usually see in Spring.

Yes.
I now have 3 berried shrimp. I think the warmer temperature from the HO fluorescent bulb has fooled the shrimp into thinking spring has come early.
I also think the cloudiness is decreasing with the old bulb.

I assume the cause is temperature. The tank is in a room with temperature of 66 to 69 F during winter, 70 to 74 F in summer. The tank has no heater. I assume the water temperature is a little higher than the air temperature, but there is not a thermometer in the tank. Reproduction has only occurred ...

OK Time for a quick update. I think I figured out the algae/bacterial bloom. And I believe it is algal. Several months ago I switched to LED lights in the tank hood. I put in all three rows of lights. I had the thought that maybe it is too much, so I put the old hood back on, with one HD fluorescent...

I'll keep watching for late arrivals. The algae does not diminish or wane--just keeps the substrate covered. For a while I thought I was seeing lots of shrimp poop sinking to the bottom, but on close examination discovered that some of the shrimp like to tear off a chunk of algae and carry it with t...

No berried shrimp in the tank, that I can see. Perhaps the breeding season is done for the year. I had a total of about 15 females bear this spring. All larvae are now swimming around. The bacterial cloudiness is still visible, but continues to lessen. I estimate there are between 400 and 500 shrimp...

Your setup is very lovely. Best wishes to you.

Yes, the bacterial bloom is still visible, but decreasing. Good to know the shrimp will consume the dead bacteria. Reproduction has slowed. At the peak there were a dozen or so berried shrimp, but now only two or three. Almost all larvae are now free-swimming. Hope everyone is having a great summer!...

A couple of months ago I mentioned a cloudiness in the tank, presumably from an algae/bacteria bloom. It has persisted until now, becoming somewhat less as time goes on. A couple of days ago I noticed an interesting change. The top half of the tank is clear, the bottom half is cloudy. See pic. The s...

The first of the larvae showed up this morning. 4 little down-hanging heads.

I had a macro ball, but it slowly dwindled. I removed it. The algae now covering the substrate is just what has grown naturally. I did not plant it.
Last count of 13 berried females.

Goodness. There are now 6 berried females. It appears the Spring orgy is is progress.

The water is still a little cloudy. I'll see how the photos turn out.
Today, the first berried shrimp of the spring season showed up. I was almost convinced the tank had reached equilibrium.
The cluster looks small, about 8 eggs.
