Hi everyone, it's been a while since I've been here. I hope this is the appropriate place to ask. I couldn't find a breeding section. Anyway, my Angelfish laid eggs and I'm attempting to hatch them artificially since they ate them last time. I have never done that -- usually let them get to wiggled stage. I am adding methylene blue to a 10 gallon aquarium where they will live (realized this may be a bad idea!). I'm wondering at what point do I remove the methylene blue? Is it safe for them as wigglers and free swimmers? Thanks!
