I need a bit of help. I bought a dalmatian molly from my neighbor pet store and around 2 weeks later I bought another one of the same kind but the new one I bought is around twice the size of the first one I bought. The newer one keeps on biting the first one but only around food time. Most of the day, they swim together and are fine but at some points of the day, the newer-bigger one keeps on biting the smaller-older one whenever it is around.
Do you think you can maybe help me as to why the newer one is like this ? Thanks so much !!
