I have both in my 29 gallon, make sure it is well planted or the CPDS will hide. I actually floated some fake plants in a corner and made a corner of the tank a jungle area, couldn't see anything in that corner. (mine where wild caught I believe) When I dropped them in there after acclimation they hide from everything. Took them 3 days to come out but they did because they had that little forest. I lost 3 because my tank didn't have enough over head cover and died from stress the first time. Now when I add to the flock the oldies teach the new ones, to come out and play. Decapped brine shrimp all the way.
