Congrats on the spawn MissMTS!

I wish you luck with them.
Im not sure that I would use any meds in a tank with eggs, even the Meth blue. Its unnatural to the sensitive eggs and you may damage them by using it. Also you are aware that the meth blue will stain your tank and everything in it.
If you have no disease present in the tank, and your fish are healthy, IMO I wouldnt add any.
Let nature take its course.. and it looks like the one angel is doing a good job so far of protecting those eggs. Keep us posted on the progress!
