i just bought 3 crawfish and put them in with the Ps. so far the Ps are ignoring them, in fact one P ran from one of the crawfish. i am going to get blue crawfish eventually but i dont wanna spend that much money on them if they arent gunna last long enough so i am experimenting with cheap regular crawfish. i know they will die eventually but maybe they will last a while. i just dont know what to feed them. i know they will eat the uneaten food and some algea and the tiny organisms and what not that is in the tank but is that enough or do i need to do sumthin extra?
