Red Tailed Shark And My Silver Mollies

[spudgun2k]

hello, i have 2 silver mollies and an orange mollie, i have 3 guppys and 3 danios and a red tailed shark. my rts only seems interested in chasing the silver mollies, hardly bothers with the pretty fins of the guppys. are my mollies strong enough to deal with the stress of being chased a lot?? i will be changing my starter 50 litre tank to a 130 litre tank soon this may help. my rts is 6-7 cm long at the moment i know he will need a bigger tank soon i just dont want to take him to my lfs if my mollies are strong enough to deal with all the hassle. are they?


thank you.

Mollies need brackish water and are likely to get diseased in FW anyway, so being stressed won't help.
