A question on culling

I'm quite new to keeping shrimp. My questiin is, how soon should I start culling? is there a specific time or number of generations before I should start the culling process? I suppose that was more than one question haha.Thank you in advance.

I pull any shrimp I'm sure I don't want in that breeding colony as soon as I see them. With Caridina, that's easy to tell early on, with Neos it can take some growing out to see what they are going to become. Either way, if you have a dedicated cull tank those can be as much fun as the tanks with perfect specimens!

Awesome. Thanks Blue Ridge. I'm keeping high grade fire red cherries. I'm sure I'll be able to tell what I want and what I need to cull in time.

Yeah, in theory, just cull the ones that don't look quite right.
Easier said than done in my case however.

In my heavily planted tanks, singling out a shrimp for culling is pretty much impossible, lol.

Make sure to leave a few males. They will present less color than the ladies and you may be tempted to net them out. They will be the ones swimming about like their tails are on fire when someone molts. With Neos you need to wait a few months for some coloring to develop before deciding which to pull.

Just a reminder that you don't have to cull.

I thought about it, attempted it, gave up immediately. Pulled enough to through in the 10G and thats about it.

Pretty amazing in a planted tank how when you try to catch a certain shrimp they immediately go into flight mode while everyone else just hangs out or swims into the net. My 40B still has enough PRCS that the offspring are nice once grown. Ive gotten alot of really cool looking wilds/semi wilds.

Also as mentioned with RCS waiting a while is necessary. A few of the "culls" I got as youngsters actually turned out to be decent to higher end RCS once grown out, and female at that.

Anyhow if you want to raise for certain colors and what not setup your system accordingly. A community tank, heavily planted is not the place to be trying to breed a certain line of shrimp.

Just be careful because male shrimp tend to be lower grade than females.... so you might accidentally remove all the males!
