ok so i got 2 ora clowns and a ora neon dottyback and i have a flatworm prob so i decided on a 6line wrasse and as soon as the dottyback noticed the wrasse it was game on. the wrasse is stuck in my xenia patch anywhere else and the neon goes nutz now to my question will this behavior change or do i some how catch the neon and throw him in my 20g?? should i give it a few days to see what happens, i do not want the wrasse being harrased as i was thinking of using him to solve my flatworm prob then trade him but now that hes in there i kinda like him and was thinking it will be his new home.
