Mervin,
Thanks for the advice. I suppose I misinterpreted some of the suggestions/information I saw on some videoos--glad to know that I can add Prime directly into the tank. So clarifying: for aging water, I will just need to let sit for 24+ hours at the same temperature and with an air stone?
And I can tell now (could not tell before--I wish I took photos of them when I first got them because Blue was looking probably the best out of the bunch initially) that Blue's eyes are way to big for his body, and his shape is slightly off. Hopefully I can get him to recover.
Thanks all.
Alex
