I seen this post and have to tell you my story.. obviously my stocking is different.. but here goes..
I DESPERATELY... wanted Cherry shrimp in my 55 gal planted. I have a tank set up for just cherry shrimp, and I was going to take some from there and throw them in my 55 gallon, so it wasn't going to cost me anything... so I did it
In it I have harlequin rasboras, kuhli loaches, ottos, rainbows, cardinals, german blue rams, BNs, and red honey gouramis, oh and clown loaches.
So I throw in some cherry shrimp (the absolutely biggest females I could find)... immediately they run for cover in the rock crevices, in the driftwood, in the plants. poof. gone.
No one tried to eat them as far as I know, and they are still there.. but they never come out. Every once and awhile I will see one hitching a ride on a leaf or it's feelers (whatever!) sticking out of the wood, but really... It's not that exciting. I have to get down and look for them. It's much more fun to watch them in their own tank. Half the reason I know there is still probably all 6 in there is I see their little molts floating on top of the tank.
I have a small planted set up with livebearers and the cherry shrimp are much more active... The livebearers probably eat some of the babies but leave the adults alone, and some of the babies.
