I absolutely love my crayfish, it seems as though he's gotten a little more comfortable as he doesn't run away from me now, and he's out and about during the day more and more often now, on the other hand, he destroyed almost all of the bacopa in his tank, as well as java fern, and he had a nice pvc tube with java moss going like crazy all over it and he trimmed it like it was a lawn, and then just ate all of it until there was nothing.
I didn't notice any aggression toward the feeder rosys I put in there, I put one in, it was in there for a few days, then I think the minnow died of its own poor health and thats probably when he went after it, then another one was in there almost a week with no signs of being attacked, but some online searching seems to suggest that some crayfish are more aggresive than others, while all crayfish will go after a dead fish.
But it seems like a 10 gallon with a small filter is great for a single crayfish, I almost want to get another one now that I have my other 10 gallon tank freed up lol.
