yeah i have several pictus in my cichlid tank and had a JD in with them until a couple months ago and never had any issues ( though i did have a problem when i tried adding another small pictus to the tank and some of them killed it but not sure which ones it was, but then I added another only slightly larger pictus to the tank and they didnt mess with it at all, so you will just have to try and see, but i never had any issue with grown pictus)
