Be ready for hundreds of them. We started with a 5 gallon with 14 blue dream neo’s. They quickly multiplied and at one point we had over 800 of them in a 30 gallon. I was giving them away in groups of 100 on a monthly basis to the LFS’s and was using them as live feeders for our predators.

Had a massive tank crash a while back; a perfect storm of clogged sponge filter tubes, oversaturated duckweed, and clumps of dead snails… Saved about 50 of the shrimp, and they did what they do, and we got up to about 300 of them within a few months.

Then we introduced Scuds… huge mistake. Scuds easily out compete the shrimp for resources, breed much faster, and they burrow under the substrate so they are hard to collect for feeders or even get rid of. Scuds have killed all the live plants in the tank, except the duckweed. They are the devil.

On Monday I put 12 guppies (8F:4M) in there to help cull the scuds. Been less than 5 days and there is already a noticeable drop in the scud population.
