Controlling RCS Population

Hello,

I would like to get some Red Cherry Shrimps for my planted aquarium. After reading this forum about how easy it is to breed these guys, my concern is that they will quickly take over my 6 gallon nano tank.

The only fish I have in it are rasbora harlequins and corydoras. I know it's doubtful, but will these fishes help eat some of the fry?

If not, is there anything I can do to prevent overpopulation?

Thanks for your help. :)

If your tank is densly planted, thenRasboras won't make any dent in the raising population of Red Cherry Shrimp/\. If not densly planted, then there is a chance Rasboras will pick out most of the young ones.

I have a lot of different Rasboras, and my plants look like christmas trees with RCS-es...

I think Harlys are more mid level feeders, I doubt they will go after anything that hits the substrate. You might not need to buy more shrimp, if they have plants to hide in, you will have more shrimp than you need. Cover the filter intake with a sponge or something. I found a colony of RCS thriving in my canister filter when I first started with them.

Removing fine/sponge pre-filter on the inlet for your filter is an easy way to trap your shrimplets. You'll ended up with mostly adults and minimum juveniles in your main tank.
I typically find around 20 live shrimplets in my canister every other week when I perform WC. Give/sell them away :proud:eek:r make fish food :angryfire.

Yeah, I started with 6 cherries that came free with 2 CPO I bought a couple months ago. Now I'm guessing there are 40-50 of the lil buggers, and currently several females with eggs. Even the CPOs are getting in on the act...the female with eggs is hiding under a glob of java moss, and I have spotted one tiny CPO on said moss. The fact that it is a nano tank with CPDs, burmese gold spot danios, and pygmy cories probably isn't helping with population control. I wish there was a fish I could get that could fit in a 16g bowfront that would help keep the population in under control.
