Hi folks,
This is my first post here (facts- yes!!)
First off, I'm the type of person who does their research before getting any pets (I seriously can't stand when people get animals on a whim, ask for help, and ignore the advice of the experienced ones on forums like this). I'm mostly concerned about the behavior changes that have resulted from my latest addition..
1) I own a 20G tank with 10 juv Danios rerio (longest is 1.25", shortest is 1", 5 juv panda corydoras.
2) My friend was selling their old aquarium and offered me some of their fish. In there was several dozen platys, and a lone, full-grown zebra longtail. As my tank isn't yet fully stocked (80% per AqAdvisor - Intelligent Freshwater Tropical Fish Aquarium Stocking Calculator and Aquarium Tank/Filter Advisor based on these being mature adults) so I offered to take the zebra danio and a few baby platies.
3) upon putting the fish in the tank, I've noticed that the male juvenile danios have been harassing the large longfin quite badly. I believe it is a female, but I'm not entirely sure (haven't seen any this massive before). My concern is that they are nipping her beautiful long fins, and that this is stressing the fish. She's much too slow to get away from the smaller shortfins. I haven't witnessed any nipping of the tail, but they seem to be headbutting her side only (possibly nipping the side fins).
So my question is... should I be concerned about the harassing? is this breeding behavior as shes getting prodded by a males only (This noob hasn't seen breeding yet)?
Any and all advice is greatly appreciated.
Thanks ya'll
