Shrimp euthanasia

Just to let you know that if I die:tombstone: and come back as a shrimp,I want to be in your tank:dive2:. lol

:laugh: Well, if you do I will make sure you have lot's of nice big fat frozen blood worms, and veggie pellets, and I won't let the other shrimp beat you up.
 
Here he is back in the breeder trap. I put him in there about an hour ago and he's already eating again. I don't know if he got anything to eat while he was out of the trap. He seemed to just be hiding a lot, feeling pretty vulnerable I imagine. I'm glad I put him back in the trap.

I didn't use a net. I have one of those plastic dip thingys like the pet stores use so I can be very gentle, and subtle, lol.

The picture below, is a shot of him from below, underneath the trap. You can see his arms in these pictures if you look carefully.

His right arm is the bigger arm. The left is this poor little gimpy thing, but he can use it, somewhat.

When I snapped this next shot he had just reached out and grabbed a big scoop of veggie pellet.

Here is one of the bully boys that beat him up. This guy is not big at all, really. He's about 2.5 inches or a little bigger. There's another about this same size that I think may be a female, because these two are very comfortable in each other's company.

The biggest guy stays hid under this chunk of Texas holey rock. I never see him come out of hiding. I don't get it. He's almost twice as big as the smaller boy. You can see him hiding there.

What's strange is that the one that got beat up was the biggest one of the bunch. Someone suggested that it must have happened to him right after a molt.

I have the injured shrimp in this ten gallon in a breeder trap. This tank has two African Dwarf frogs, and a whole bunch of Red Ramshorns that came in on some plants.

I set up the small, five gallon Eclipse MiniBow, which I have used as a hospital in the past, to house the three other shrimp. I believe that two of them have paired off as a couple, leaving one other male that stays hidden. I think he doesn't want to end up like the other big guy that got beat up.

The injured shrimp is still doing well in the breeder trap. He eats a veggie pellet and a brine shrimp pellets every day. I think he's going to molt again pretty soon.
 
I think your shrimp aren't redclaws and instead belong to the M. rosenbergii species group.

At any rate, I've experienced similar things with my M. carcinus. I discovered one of them being cannibalized by a neighbor that had climbed over a tank divider as it was molting. The victim lost all of its walking and most of its claw-bearing legs, part of its rostrum, and a fringing portion of its cephalothorax. I isolated it in a 10-gallon tank (where it fluttered around clumsily with its pleopods but led an otherwise grublike existence) and fed it by hand. Within a few weeks, I saw incipient limb regrowth (soft, stubby legs curling out from the stumps); they became functional with its first post-attack molt. These regenerated limbs were smaller than they'd originally been, of course, but they continued to grow with successive molts.

Pre-molt (note partial limb regeneration):

Apparently this isn't unheard of with Macrobrachium. Originally posted by Hanno ("Median") on the German sister board of crustaforum.com:
