Question
I have a 125 gallon tank I have many live plants in there and some fake ones and there is alot of cover. I have a school of 6 giant danios 3 full grown silver dollars 1 rainbow shark 3 bleeding heart tetras and 1 gourami. I added 2 sailfin mollies in there. 1 male 1 female their both fully grown I would say they are 3 and a half inches. But my problem is when I put them in there the giant danios started chasing them around. Do you think I should move the mollies to a different tank or keep them in there. I think it might be because they are the new fish so the other fish will pick on them. But I just want to know what I should do.

Answer
HiYa!

Unfortunately fish do chase fish. If it was me I would leave them in there and just monitor how they go. If the Danios are constantly chasing them and not leaving them alone at all, then yes, move them but you should find that the chasing should stop after a couple of days to a week, they are more than likely chasing them as they are new to the tank and the Danios are asserting their 'dominance' and letting the Mollies know they are the 'new guys' so to speak.

Hope this helps!

Cheers! Rach
