Hey guys, i got a male swordtail in my tank with my 2 other female swordtails hu r both pregnant and he seems to be stressin them and chasing them out plus he's an aggressive large fish so he could eat any babies that aren't captured. I want to move him into my other tank while the girls are pregnant and when i want to have more babies. Will it be okay to move him into my other tank if he has been moved there before and also how would i do this? in the past i have put him into a glass with half water from his own tank and half of the downstairs tank? any suggestions?
