this is the 2nd thread first one died because i asked the wrong question. How well do dats do with crayfish? specifically a thinbar and a blue cray, right now the crayfish is about an inch bigger than the dat. the cray is in with a few exodons and doesn't seem to pay any attention to then, but does but heads with a common pleco every once in awhile.any info or past experiences would be greatly appreciated, thanx in advance.
