The other day i bought another blue damsel and added him to my tank with a domino (large) the domino harassed him and managed to bite off the poor guys tail.. so i moved the blue to my 30 gallon with a yellowtail and 2 clowns, he was still being harassed by the yellow tail and his tail was concerning me that it would not heal, he has been eating well but i thought it best to keep him from the other fish
today i went out and bought a breeding net (the guy at store said it would work fine for him) and i set it up it is pretty small
so it took me a while to catch him but i finally placed him in the net and since then he has been scared and moping around the bottom and occasionally freaking out and trying to get out
i was wondering if the breeding net is even necessary and his tail will heal on its own or am i just causing him more stress and making him more prone to infection??

Thanks for any advice!
