I just upgraded my shrimp from a 1 gallon jar to a 3 gallon halfmoon tank with a light. I also was gifted ecospheres quite awhile ago. One of these became really clean with no algae remaining. So, i broke it open and put the 2 shrimp in with my tank after drip acclimating them. They've all been doing really well and seem a lot happier in the larger tank. A few days after I noticed a moult. I think this is a good sign?

But I noticed maybe 1 or 2 of the shrimp being more active than normal, swimming around quite a bit more and chasing other shrimp around. I have not fed them since putting them in the new tank. I'm not sure if this is breeding behavior or possible aggression?

Welcome to the forum! That’s great about the ecosphere rescue, with regards the shrimps behaviour I’d say it’s mating because a female has moulted. Once the females moult they can receive the males sperm for a short amount of time so the males can sense this and frantically search for her.

Edit: by the way I love the rock layout in your tank :)

I'm so happy to hear that! I had a berried female long ago in the first jar I set up but no eggs ever hatched. Very disappointing.
Thank you so much!

Nice tank. Almost thought it was a full circle tank. Do you know if that manufacturer makes a full circle one?

Analogy. Molt = taking clothes off.

That manufacturer doesnt seem to make any but there are a few decent cylindrical tanks on amazon for decent prices 👍

Any sign of berried females?
