I tried a lot of different shrimps and think that a lot of species are good for Parosphromenus tanks. Expecially the ones who use to have babies in normal Parosphromenus tanks are interesting. They will clean the tank and become food for a while. In my case I handle C.pariventata, they should not life in my water, but they do.
They seem not to eat the young of the Paros, but I am not sure at this point.
Have anybody information about that?
In my tank two P. sumatranus grew up. With shrimps and a female of P. linkei.
The shrimprate is going down this time although there are enouth female with eggs. Maybe the Paros specialize.
In my opinion shrimps are good in tanks wich are not in use for intensive breeding.
