When fish stress fish - can this be prevented?
I'm still learning about my aquarium. I'm puzzled by one thing - do all kind of fish stress out fish, or is it specific breeds? Probably the answer is 'all.'
Started with guppies, now I see it with platys. I have balloon mollys and it seems to me those can endure more pressure.
So I have 8 mollys and 2 platys in a 20 gallon. I bought two bumblebee mollys and platy in early November. Just a few weeks ago, the platy started with mating with one of the bb mollys to the point of stressing her. Found her dead Saturday. Now he went after my 2nd bb molly, stressing her to the point she is twitching and hiding. By stressing I mean swimming side by side or going next to her and making her jump, and simply following her wherever she goes. I am certain I'll find her dead by the end of the week if not sooner.
Both bb mollys were active, eating, and quite happy for 2 months, coexisting, and then the platy just started this maybe 2, 3 weeks ago.
So is it just the platy and guppy that do this kind of attack? I still haven't seen my balloon mollys get this weak with their mating, and I do prefer them the most. It just bothers me that they die this way so suddenly! Can this be prevented (without separation?)
