Well they (3 @ about 2.5" - 3") are currently residing with 4 Amphilophus Xiloaensis from TUIC.
It looks as though I will be monitoring them very closely and moving them to thier own tank before they decimate my Xilo's. At this stage the Xilo's are dominating but I will not be taking any chances.
Thank you all for the input.
If there is anyone else out there who keeps these guys or has any additional info, I would appreciate hearing of your experiences as well.
